  •            Prioritizing and Deferring Removal of Certain
    Aliens Unlawfully Present in the United States
    The Department of Homeland Security’s proposed policy to prioritize the removal of
    certain aliens unlawfully present in the United States would be a permissible exercise
    of DHS’s discretion to enforce the immigration laws.
    DHS’s proposed deferred action program for parents of U.S. citizens and legal permanent
    residents would also be a permissible exercise of DHS’s discretion to enforce the im-
    migration laws.
    DHS’s proposed deferred action program for parents of recipients of deferred action
    under the Deferred Action for Childhood Arrivals program would not be a permissible
    exercise of DHS’s enforcement discretion.

    MEMORANDUM OPINION FOR THE
    SECRETARY OF HOMELAND SECURITY
    AND THE COUNSEL TO THE PRESIDENT *
    You have asked two questions concerning the scope of the Department
    of Homeland Security’s discretion to enforce the immigration laws. First,
    you have asked whether, in light of the limited resources available to the
    Department (“DHS”) to remove aliens unlawfully present in the United
    * Editor’s Note: This opinion has been withdrawn. The opinion’s principal subject, the
    Deferred Action for Parents of Americans and Lawful Permanent Residents (“DAPA”)
    policy, was preliminarily enjoined before it went into effect. See Texas v. United States,
    
    86 F. Supp. 3d 591
     (S.D. Tex.), aff ’d, 
    809 F.3d 134
     (5th Cir. 2015), aff ’d by an equally
    divided Court, 
    136 S. Ct. 2271
     (2016). Based on the reasoning in the Fifth Circuit’s
    decision, on September 4, 2017, Attorney General Sessions concluded that the related
    Deferred Action for Childhood Arrivals (“DACA”) policy, which is briefly discussed in
    footnote 8 of this opinion, was unlawful. See Letter for Elaine Duke, Acting Secretary of
    Homeland Security, from Jefferson B. Sessions III, Attorney General (Sept. 4, 2017).
    Although the Acting Secretary of Homeland Security announced the rescission of DACA
    on September 5, 2017, the Supreme Court vacated that decision and remanded for further
    proceedings. See Dep’t of Homeland Sec. v. Regents of Univ. of Cal., 
    140 S. Ct. 1891
    (2020). In order to maximize the Acting Secretary’s discretion on remand, and without
    regard to the merits of the legal issues, Attorney General Barr withdrew Attorney General
    Sessions’ September 4, 2017 letter and, for the same reason, further directed this Office to
    withdraw this opinion. See Letter for Chad F. Wolf, Acting Secretary of Homeland
    Security, from William P. Barr, Attorney General (June 30, 2020).

    States, it would be legally permissible for the Department to implement a
    policy prioritizing the removal of certain categories of aliens over others.
    DHS has explained that although there are approximately 11.3 million
    undocumented aliens in the country, it has the resources to remove fewer
    than 400,000 such aliens each year. DHS’s proposed policy would priori-
    tize the removal of aliens who present threats to national security, public
    safety, or border security. Under the proposed policy, DHS officials could
    remove an alien who did not fall into one of these categories provided that
    an Immigration and Customs Enforcement (“ICE”) Field Office Director
    determined that “removing such an alien would serve an important federal
    interest.” Draft Memorandum for Thomas S. Winkowski, Acting Director,
    ICE, et al., from Jeh Charles Johnson, Secretary of Homeland Security,
    Re: Policies for the Apprehension, Detention, and Removal of Undocu-
    mented Immigrants at 5 (Nov. 17, 2014) (“Johnson Prioritization Memo-
    randum”).
    Second, you have asked whether it would be permissible for DHS to
    extend deferred action, a form of temporary administrative relief from
    removal, to certain aliens who are the parents of children who are present
    in the United States. Specifically, DHS has proposed to implement a
    program under which an alien could apply for, and would be eligible to
    receive, deferred action if he or she is not a DHS removal priority under
    the policy described above; has continuously resided in the United States
    since before January 1, 2010; has a child who is either a U.S. citizen or a
    lawful permanent resident; is physically present in the United States both
    when DHS announces its program and at the time of application for
    deferred action; and presents “no other factors that, in the exercise of
    discretion, make[] the grant of deferred action inappropriate.” Draft
    Memorandum for Leon Rodriguez, Director, U.S. Citizenship and Immi-
    gration Services, et al., from Jeh Charles Johnson, Secretary of Homeland
    Security, Re: Exercising Prosecutorial Discretion with Respect to Indi-
    viduals Who Came to the United States as Children and Others at 4
    (Nov. 17, 2014) (“Johnson Deferred Action Memorandum”). You have
    also asked whether DHS could implement a similar program for parents of
    individuals who have received deferred action under the Deferred Action
    for Childhood Arrivals (“DACA”) program.
    As has historically been true of deferred action, these proposed deferred
    action programs would not “legalize” any aliens who are unlawfully
    40
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    present in the United States: Deferred action does not confer any lawful
    immigration status, nor does it provide a path to obtaining permanent
    residence or citizenship. Grants of deferred action under the proposed
    programs would, rather, represent DHS’s decision not to seek an alien’s
    removal for a prescribed period of time. See generally Reno v. Am.-Arab
    Anti-Discrim. Comm., 
    525 U.S. 471
    , 483–84 (1999) (describing deferred
    action). Under decades-old regulations promulgated pursuant to authority
    delegated by Congress, see 
    8 U.S.C. §§ 1103
    (a)(3), 1324a(h)(3), aliens
    who are granted deferred action—like certain other categories of aliens
    who do not have lawful immigration status, such as asylum applicants—
    may apply for authorization to work in the United States in certain
    circumstances, 8 C.F.R. § 274a.12(c)(14) (providing that deferred action
    recipients may apply for work authorization if they can show an “eco-
    nomic necessity for employment”); see also id. § 109.1(b)(7) (1982).
    Under DHS policy guidance, a grant of deferred action also suspends
    an alien’s accrual of unlawful presence for purposes of 
    8 U.S.C. § 1182
    (a)(9)(B)(i) and (a)(9)(C)(i)(I), provisions that restrict the admis-
    sion of aliens who have departed the United States after having been
    unlawfully present for specified periods of time. A grant of deferred
    action under the proposed programs would remain in effect for three
    years, subject to renewal, and could be terminated at any time at DHS’s
    discretion. See Johnson Deferred Action Memorandum at 2, 5.
    For the reasons discussed below, we conclude that DHS’s proposed
    prioritization policy and its proposed deferred action program for parents
    of U.S. citizens and lawful permanent residents would be permissible
    exercises of DHS’s discretion to enforce the immigration laws. We further
    conclude that, as it has been described to us, the proposed deferred action
    program for parents of DACA recipients would not be a permissible
    exercise of enforcement discretion.
    I.
    We first address DHS’s authority to prioritize the removal of certain
    categories of aliens over others. We begin by discussing some of the
    sources and limits of DHS’s enforcement discretion under the immigra-
    tion laws, and then analyze DHS’s proposed prioritization policy in light
    of these considerations.

    38 Op. O.L.C. 39
     (2014)
    A.
    DHS’s authority to remove aliens from the United States rests on the
    Immigration and Nationality Act of 1952 (“INA”), as amended, 
    8 U.S.C. § 1101
     et seq. In the INA, Congress established a comprehensive scheme
    governing immigration and naturalization. The INA specifies certain
    categories of aliens who are inadmissible to the United States. See
    
    8 U.S.C. § 1182
    . It also specifies “which aliens may be removed from the
    United States and the procedures for doing so.” Arizona v. United States,
    
    132 S. Ct. 2492
    , 2499 (2012). “Aliens may be removed if they were
    inadmissible at the time of entry, have been convicted of certain crimes,
    or meet other criteria set by federal law.” 
    Id.
     (citing 
    8 U.S.C. § 1227
    );
    see 
    8 U.S.C. § 1227
    (a) (providing that “[a]ny alien . . . in and admitted to
    the United States shall, upon the order of the Attorney General, be re-
    moved if the alien” falls within one or more classes of deportable al-
    iens); see also 
    8 U.S.C. § 1182
    (a) (listing classes of aliens ineligible to
    receive visas or be admitted to the United States). Removal proceedings
    ordinarily take place in federal immigration courts administered by the
    Executive Office for Immigration Review, a component of the Depart-
    ment of Justice. See 
    id.
     § 1229a (governing removal proceedings); see
    also id. §§ 1225(b)(1)(A), 1228(b) (setting out expedited removal pro-
    cedures for certain arriving aliens and certain aliens convicted of aggra-
    vated felonies).
    Before 2003, the Department of Justice, through the Immigration and
    Naturalization Service (“INS”), was also responsible for providing immi-
    gration-related administrative services and generally enforcing the immi-
    gration laws. In the Homeland Security Act of 2002, Pub. L. No. 107-296,
    
    116 Stat. 2135
    , Congress transferred most of these functions to DHS,
    giving it primary responsibility both for initiating removal proceedings
    and for carrying out final orders of removal. See 
    6 U.S.C. § 101
     et seq.;
    see also Clark v. Martinez, 
    543 U.S. 371
    , 374 n.1 (2005) (noting that the
    immigration authorities previously exercised by the Attorney General and
    INS “now reside” in the Secretary of Homeland Security and DHS). The
    Act divided INS’s functions among three different agencies within DHS:
    U.S. Citizenship and Immigration Services (“USCIS”), which oversees
    legal immigration into the United States and provides immigration and
    naturalization services to aliens; ICE, which enforces federal laws govern-
    ing customs, trade, and immigration; and U.S. Customs and Border Pro-
    tection (“CBP”), which monitors and secures the Nation’s borders and
    42
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    ports of entry. See Homeland Security Act §§ 403, 442, 451, 471, 116
    Stat. at 2178, 2193, 2195, 2205; see also Name Change from the Bureau
    of Citizenship and Immigration Services to U.S. Citizenship and Immigra-
    tion Services, 
    69 Fed. Reg. 60,938
    , 60,938 (Oct. 13, 2004); Name Change
    of Two DHS Components, 
    75 Fed. Reg. 12,445
    , 12,445 (Mar. 16, 2010).
    The Secretary of Homeland Security is thus now “charged with the ad-
    ministration and enforcement of [the INA] and all other laws relating to
    the immigration and naturalization of aliens.” 
    8 U.S.C. § 1103
    (a)(1).
    As a general rule, when Congress vests enforcement authority in an ex-
    ecutive agency, that agency has the discretion to decide whether a particu-
    lar violation of the law warrants prosecution or other enforcement action.
    This discretion is rooted in the President’s constitutional duty to “take
    Care that the Laws be faithfully executed,” U.S. Const. art. II, § 3, and it
    reflects a recognition that the “faithful[]” execution of the law does not
    necessarily entail “act[ing] against each technical violation of the statute”
    that an agency is charged with enforcing. Heckler v. Chaney, 
    470 U.S. 821
    , 831 (1985). Rather, as the Supreme Court explained in Chaney, the
    decision whether to initiate enforcement proceedings is a complex judg-
    ment that calls on the agency to “balanc[e] . . . a number of factors which
    are peculiarly within its expertise.” 
    Id.
     These factors include “whether
    agency resources are best spent on this violation or another, whether the
    agency is likely to succeed if it acts, whether the particular enforcement
    action requested best fits the agency’s overall policies, and . . . whether
    the agency has enough resources to undertake the action at all.” Id.; cf.
    United States v. Armstrong, 
    517 U.S. 456
    , 465 (1996) (recognizing that
    exercises of prosecutorial discretion in criminal cases involve considera-
    tion of “‘[s]uch factors as the strength of the case, the prosecution’s
    general deterrence value, the Government’s enforcement priorities, and
    the case’s relationship to the Government’s overall enforcement plan’”
    (quoting Wayte v. United States, 
    470 U.S. 598
    , 607 (1985))). In Chaney,
    the Court considered and rejected a challenge to the Food and Drug Ad-
    ministration’s refusal to initiate enforcement proceedings with respect to
    alleged violations of the Federal Food, Drug, and Cosmetic Act, conclud-
    ing that an agency’s decision not to initiate enforcement proceedings is
    presumptively immune from judicial review. See 470 U.S. at 832. The
    Court explained that, while Congress may “provide[] guidelines for the
    agency to follow in exercising its enforcement powers,” in the absence of
    such “legislative direction,” an agency’s non-enforcement determination
    43
    
    38 Op. O.L.C. 39
     (2014)
    is, much like a prosecutor’s decision not to indict, a “special province of
    the Executive.” 
    Id.
     at 832–33.
    The principles of enforcement discretion discussed in Chaney apply
    with particular force in the context of immigration. Congress enacted the
    INA against a background understanding that immigration is “a field
    where flexibility and the adaptation of the congressional policy to infinite-
    ly variable conditions constitute the essence of the program.” United
    States ex rel. Knauff v. Shaughnessy, 
    338 U.S. 537
    , 543 (1950) (internal
    quotation marks omitted). Consistent with this understanding, the INA
    vested the Attorney General (now the Secretary of Homeland Security)
    with broad authority to “establish such regulations; . . . issue such instruc-
    tions; and perform such other acts as he deems necessary for carrying out
    his authority” under the statute. 
    8 U.S.C. § 1103
    (a)(3). Years later, when
    Congress created DHS, it expressly charged DHS with responsibility for
    “[e]stablishing national immigration enforcement policies and priorities.”
    Homeland Security Act § 402(5), 116 Stat. at 2178 (codified at 
    6 U.S.C. § 202
    (5)).
    With respect to removal decisions in particular, the Supreme Court has
    recognized that “the broad discretion exercised by immigration officials”
    is a “principal feature of the removal system” under the INA. Arizona,
    
    132 S. Ct. at 2499
    . The INA expressly authorizes immigration officials to
    grant certain forms of discretionary relief from removal for aliens, in-
    cluding parole, 
    8 U.S.C. § 1182
    (d)(5)(A); asylum, 
    id.
     § 1158(b)(1)(A);
    and cancellation of removal, id. § 1229b. But in addition to administering
    these statutory forms of relief, “[f ]ederal officials, as an initial matter,
    must decide whether it makes sense to pursue removal at all.” Arizona,
    
    132 S. Ct. at 2499
    . And, as the Court has explained, “[a]t each stage” of
    the removal process—“commenc[ing] proceedings, adjudicat[ing] cases,
    [and] execut[ing] removal orders”—immigration officials have “discre-
    tion to abandon the endeavor.” Am.-Arab Anti-Discrim. Comm., 
    525 U.S. at 483
     (alterations in original) (quoting 
    8 U.S.C. § 1252
    (g)). Deciding
    whether to pursue removal at each of these stages implicates a wide
    range of considerations. As the Court observed in Arizona:
    Discretion in the enforcement of immigration law embraces immedi-
    ate human concerns. Unauthorized workers trying to support their
    families, for example, likely pose less danger than alien smugglers
    or aliens who commit a serious crime. The equities of an individual
    case may turn on many factors, including whether the alien has chil-
    44
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    dren born in the United States, long ties to the community, or a rec-
    ord of distinguished military service. Some discretionary decisions
    involve policy choices that bear on this Nation’s international rela-
    tions. . . . The foreign state may be mired in civil war, complicit in
    political persecution, or enduring conditions that create a real risk
    that the alien or his family will be harmed upon return. The dynamic
    nature of relations with other countries requires the Executive
    Branch to ensure that enforcement policies are consistent with this
    Nation’s foreign policy with respect to these and other realities.
    
    132 S. Ct. at 2499
    .
    Immigration officials’ discretion in enforcing the laws is not, however,
    unlimited. Limits on enforcement discretion are both implicit in, and
    fundamental to, the Constitution’s allocation of governmental powers
    between the two political branches. See, e.g., Youngstown Sheet & Tube
    Co. v. Sawyer, 
    343 U.S. 579
    , 587–88 (1952). These limits, however, are
    not clearly defined. The open-ended nature of the inquiry under the Take
    Care Clause—whether a particular exercise of discretion is “faithful[]” to
    the law enacted by Congress—does not lend itself easily to the application
    of set formulas or bright-line rules. And because the exercise of enforce-
    ment discretion generally is not subject to judicial review, see Chaney,
    
    470 U.S. at
    831–33, neither the Supreme Court nor the lower federal
    courts have squarely addressed its constitutional bounds. Rather, the
    political branches have addressed the proper allocation of enforcement
    authority through the political process. As the Court noted in Chaney,
    Congress “may limit an agency’s exercise of enforcement power if it
    wishes, either by setting substantive priorities, or by otherwise circum-
    scribing an agency’s power to discriminate among issues or cases it will
    pursue.” 
    Id. at 833
    . The history of immigration policy illustrates this
    principle: Since the INA was enacted, the Executive Branch has on nu-
    merous occasions exercised discretion to extend various forms of immi-
    gration relief to categories of aliens for humanitarian, foreign policy, and
    other reasons. When Congress has been dissatisfied with executive action,
    it has responded, as Chaney suggests, by enacting legislation to limit the
    Executive’s discretion in enforcing the immigration laws. 1
    1 See, e.g., Adam B. Cox & Cristina M. Rodríguez, The President and Immigration
    Law, 
    119 Yale L.J. 458
    , 503–05 (2009) (describing Congress’s response to its dissatisfac-
    tion with the Executive’s use of parole power for refugee populations in the 1960s and
    45
    
    38 Op. O.L.C. 39
     (2014)
    Nonetheless, the nature of the Take Care duty does point to at least
    four general (and closely related) principles governing the permissible
    scope of enforcement discretion that we believe are particularly relevant
    here. First, enforcement decisions should reflect “factors which are
    peculiarly within [the enforcing agency’s] expertise.” Chaney, 470 U.S.
    at 831. Those factors may include considerations related to agency re-
    sources, such as “whether the agency has enough resources to undertake
    the action,” or “whether agency resources are best spent on this violation
    or another.” Id. Other relevant considerations may include “the proper
    ordering of [the agency’s] priorities,” id. at 832, and the agency’s as-
    sessment of “whether the particular enforcement action [at issue] best fits
    the agency’s overall policies,” id. at 831.
    Second, the Executive cannot, under the guise of exercising enforce-
    ment discretion, attempt to effectively rewrite the laws to match its policy
    preferences. See id. at 833 (an agency may not “disregard legislative
    direction in the statutory scheme that [it] administers”). In other words, an
    agency’s enforcement decisions should be consonant with, rather than
    contrary to, the congressional policy underlying the statutes the agency is
    charged with administering. Cf. Youngstown, 
    343 U.S. at 637
     (Jackson, J.,
    concurring) (“When the President takes measures incompatible with the
    expressed or implied will of Congress, his power is at its lowest ebb.”);
    Nat’l Ass’n of Home Builders v. Defenders of Wildlife, 
    551 U.S. 644
    , 658
    (2007) (explaining that where Congress has given an agency the power to
    administer a statutory scheme, a court will not vacate the agency’s deci-
    sion about the proper administration of the statute unless, among other
    things, the agency “‘has relied on factors which Congress had not intend-
    ed it to consider’” (quoting Motor Vehicle Mfrs. Ass’n of U.S., Inc. v.
    State Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983))).
    Third, the Executive Branch ordinarily cannot, as the Court put it in
    Chaney, “‘consciously and expressly adopt[] a general policy’ that is so
    extreme as to amount to an abdication of its statutory responsibilities.”
    470 U.S. at 833 n.4 (quoting Adams v. Richardson, 
    480 F.2d 1159
    , 1162
    (D.C. Cir. 1973) (en banc)); see 
    id.
     (noting that in situations where an
    agency had adopted such an extreme policy, “the statute conferring au-
    thority on the agency might indicate that such decisions were not ‘com-
    1970s); see also, e.g., infra note 5 (discussing legislative limitations on voluntary depar-
    ture and extended voluntary departure).
    46
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    mitted to agency discretion’”). Abdication of the duties assigned to the
    agency by statute is ordinarily incompatible with the constitutional obliga-
    tion to faithfully execute the laws. But see, e.g., Presidential Authority to
    Decline to Execute Unconstitutional Statutes, 
    18 Op. O.L.C. 199
    , 200
    (1994) (noting that under the Take Care Clause, “the President is required
    to act in accordance with the laws—including the Constitution, which
    takes precedence over other forms of law”).
    Finally, lower courts, following Chaney, have indicated that non-
    enforcement decisions are most comfortably characterized as judicially
    unreviewable exercises of enforcement discretion when they are made on
    a case-by-case basis. See, e.g., Kenney v. Glickman, 
    96 F.3d 1118
    , 1123
    (8th Cir. 1996); Crowley Caribbean Transp., Inc. v. Peña, 
    37 F.3d 671
    ,
    676–77 (D.C. Cir. 1994). That reading of Chaney reflects a conclusion
    that case-by-case enforcement decisions generally avoid the concerns
    mentioned above. Courts have noted that “single-shot non-enforcement
    decisions” almost inevitably rest on “the sort of mingled assessments of
    fact, policy, and law . . . that are, as Chaney recognizes, peculiarly within
    the agency’s expertise and discretion.” Crowley Caribbean Transp., 
    37 F.3d at
    676 –77 (emphasis omitted). Individual enforcement decisions
    made on the basis of case-specific factors are also unlikely to constitute
    “general polic[ies] that [are] so extreme as to amount to an abdication of
    [the agency’s] statutory responsibilities.” 
    Id. at 677
     (quoting Chaney, 477
    U.S. at 833 n.4). That does not mean that all “general policies” respecting
    non-enforcement are categorically forbidden: Some “general policies”
    may, for example, merely provide a framework for making individualized,
    discretionary assessments about whether to initiate enforcement actions in
    particular cases. Cf. Reno v. Flores, 
    507 U.S. 292
    , 313 (1993) (explaining
    that an agency’s use of “reasonable presumptions and generic rules” is not
    incompatible with a requirement to make individualized determinations).
    But a general policy of non-enforcement that forecloses the exercise of
    case-by-case discretion poses “special risks” that the agency has exceeded
    the bounds of its enforcement discretion. Crowley Caribbean Transp.,
    
    37 F.3d at 677
    .
    B.
    We now turn, against this backdrop, to DHS’s proposed prioritization
    policy. In their exercise of enforcement discretion, DHS and its predeces-
    47
    
    38 Op. O.L.C. 39
     (2014)
    sor, INS, have long employed guidance instructing immigration officers
    to prioritize the enforcement of the immigration laws against certain
    categories of aliens and to deprioritize their enforcement against others.
    See, e.g., INS Operating Instructions § 103(a)(1)(i) (1962); Memorandum
    for All Field Office Directors, ICE, et al., from John Morton, Director,
    ICE, Re: Exercising Prosecutorial Discretion Consistent with the Civil
    Immigration Enforcement Priorities of the Agency for the Apprehension,
    Detention, and Removal of Aliens (June 17, 2011); Memorandum for All
    ICE Employees from John Morton, Director, ICE, Re: Civil Immigration
    Enforcement: Priorities for the Apprehension, Detention, and Removal of
    Aliens (Mar. 2, 2011); Memorandum for Regional Directors, INS, et al.,
    from Doris Meissner, Commissioner, INS, Re: Exercising Prosecutorial
    Discretion (Nov. 17, 2000). The policy DHS proposes, which is similar to
    but would supersede earlier policy guidance, is designed to “provide
    clearer and more effective guidance in the pursuit” of DHS’s enforcement
    priorities: namely, “threats to national security, public safety and border
    security.” Johnson Prioritization Memorandum at 1.
    Under the proposed policy, DHS would identify three categories of
    undocumented aliens who would be priorities for removal from the
    United States. See generally id. at 3–5. The highest priority category
    would include aliens who pose particularly serious threats to national
    security, border security, or public safety, including aliens engaged in or
    suspected of espionage or terrorism, aliens convicted of offenses related
    to participation in criminal street gangs, aliens convicted of certain
    felony offenses, and aliens apprehended at the border while attempting to
    enter the United States unlawfully. See id. at 3. The second-highest
    priority would include aliens convicted of multiple or significant misde-
    meanor offenses; aliens who are apprehended after unlawfully entering
    the United States who cannot establish that they have been continuously
    present in the United States since January 1, 2014; and aliens determined
    to have significantly abused the visa or visa waiver programs. See id. at
    3–4. The third priority category would include other aliens who have
    been issued a final order of removal on or after January 1, 2014. See id.
    at 4. The policy would also provide that none of these aliens should be
    prioritized for removal if they “qualify for asylum or another form of
    relief under our laws.” Id. at 3–5.
    48
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    The policy would instruct that resources should be directed to these
    priority categories in a manner “commensurate with the level of prioriti-
    zation identified.” Id. at 5. It would, however, also leave significant room
    for immigration officials to evaluate the circumstances of individual
    cases. See id. (stating that the policy “requires DHS personnel to exercise
    discretion based on individual circumstances”). For example, the policy
    would permit an ICE Field Office Director, CBP Sector Chief, or CBP
    Director of Field Operations to deprioritize the removal of an alien falling
    in the highest priority category if, in her judgment, “there are compelling
    and exceptional factors that clearly indicate the alien is not a threat to
    national security, border security, or public safety and should not there-
    fore be an enforcement priority.” Id. at 3. Similar discretionary provisions
    would apply to aliens in the second and third priority categories. 2 The
    policy would also provide a non-exhaustive list of factors DHS personnel
    should consider in making such deprioritization judgments. 3 In addition,
    the policy would expressly state that its terms should not be construed “to
    prohibit or discourage the apprehension, detention, or removal of aliens
    unlawfully in the United States who are not identified as priorities,” and
    would further provide that “[i]mmigration officers and attorneys may
    pursue removal of an alien not identified as a priority” if, “in the judg-
    ment of an ICE Field Office Director, removing such an alien would
    serve an important federal interest.” Id. at 5.
    DHS has explained that the proposed policy is designed to respond to
    the practical reality that the number of aliens who are removable under
    2 Under the proposed policy, aliens in the second tier could be deprioritized if, “in the
    judgment of an ICE Field Office Director, CBP Sector Chief, CBP Director of Field
    Operations, USCIS District Director, or USCIS Service Center Director, there are factors
    indicating the alien is not a threat to national security, border security, or public safety,
    and should not therefore be an enforcement priority.” Johnson Prioritization Memoran-
    dum at 4. Aliens in the third tier could be deprioritized if, “in the judgment of an immi-
    gration officer, the alien is not a threat to the integrity of the immigration system or there
    are factors suggesting the alien should not be an enforcement priority.” Id. at 5.
    3 These factors include “extenuating circumstances involving the offense of convic-
    tion; extended length of time since the offense of conviction; length of time in the United
    States; military service; family or community ties in the United States; status as a victim,
    witness or plaintiff in civil or criminal proceedings; or compelling humanitarian factors
    such as poor health, age, pregnancy, a young child or a seriously ill relative.” Id. at 6.

    38 Op. O.L.C. 39
     (2014)
    the INA vastly exceeds the resources Congress has made available to
    DHS for processing and carrying out removals. The resource constraints
    are striking. As noted, DHS has informed us that there are approximately
    11.3 million undocumented aliens in the country, but that Congress has
    appropriated sufficient resources for ICE to remove fewer than 400,000
    aliens each year, a significant percentage of whom are typically encoun-
    tered at or near the border rather than in the interior of the country. See
    E-mail for Karl R. Thompson, Principal Deputy Assistant Attorney Gen-
    eral, Office of Legal Counsel, from David Shahoulian, Deputy General
    Counsel, DHS, Re: Immigration Opinion (Nov. 19, 2014) (“Shahoulian
    E-mail”). The proposed policy explains that, because DHS “cannot re-
    spond to all immigration violations or remove all persons illegally in the
    United States,” it seeks to “prioritize the use of enforcement personnel,
    detention space, and removal assets” to “ensure that use of its limited
    resources is devoted to the pursuit of” DHS’s highest priorities. Johnson
    Prioritization Memorandum at 2.
    In our view, DHS’s proposed prioritization policy falls within the scope
    of its lawful discretion to enforce the immigration laws. To begin with,
    the policy is based on a factor clearly “within [DHS’s] expertise.”
    Chaney, 
    470 U.S. at 831
    . Faced with sharply limited resources, DHS
    necessarily must make choices about which removals to pursue and which
    removals to defer. DHS’s organic statute itself recognizes this inevitable
    fact, instructing the Secretary to establish “national immigration enforce-
    ment policies and priorities.” 
    6 U.S.C. § 202
    (5). And an agency’s need to
    ensure that scarce enforcement resources are used in an effective manner
    is a quintessential basis for the use of prosecutorial discretion. See
    Chaney, 
    470 U.S. at 831
     (among the factors “peculiarly within [an agen-
    cy’s] expertise” are “whether agency resources are best spent on this
    violation or another” and “whether the agency has enough resources to
    undertake the action at all”).
    The policy DHS has proposed, moreover, is consistent with the removal
    priorities established by Congress. In appropriating funds for DHS’s
    enforcement activities—which, as noted, are sufficient to permit the
    removal of only a fraction of the undocumented aliens currently in the
    country—Congress has directed DHS to “prioritize the identification and
    removal of aliens convicted of a crime by the severity of that crime.”

    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    Department of Homeland Security Appropriations Act, 2014, Pub. L. No.
    113-76, div. F, tit. II, 
    128 Stat. 5
    , 251 (“DHS Appropriations Act”). Con-
    sistent with this directive, the proposed policy prioritizes individuals
    convicted of criminal offenses involving active participation in a criminal
    street gang, most offenses classified as felonies in the convicting jurisdic-
    tion, offenses classified as “aggravated felonies” under the INA, and
    certain misdemeanor offenses. Johnson Prioritization Memorandum at
    3–4. The policy ranks these priority categories according to the severity of
    the crime of conviction. The policy also prioritizes the removal of other
    categories of aliens who pose threats to national security or border securi-
    ty, matters about which Congress has demonstrated particular concern.
    See, e.g., 
    8 U.S.C. § 1226
    (c)(1)(D) (providing for detention of aliens
    charged with removability on national security grounds); 
    id.
     § 1225(b),
    (c) (providing for an expedited removal process for certain aliens appre-
    hended at the border). The policy thus raises no concern that DHS has
    relied “on factors which Congress had not intended it to consider.” Nat’l
    Ass’n of Home Builders, 
    551 U.S. at 658
    .
    Further, although the proposed policy is not a “single-shot non-enforce-
    ment decision,” neither does it amount to an abdication of DHS’s statuto-
    ry responsibilities, or constitute a legislative rule overriding the com-
    mands of the substantive statute. Crowley Caribbean Transp., 
    37 F.3d at
    676–77. The proposed policy provides a general framework for exercising
    enforcement discretion in individual cases, rather than establishing an
    absolute, inflexible policy of not enforcing the immigration laws in cer-
    tain categories of cases. Given that the resources Congress has allocated
    to DHS are sufficient to remove only a small fraction of the total popula-
    tion of undocumented aliens in the United States, setting forth written
    guidance about how resources should presumptively be allocated in par-
    ticular cases is a reasonable means of ensuring that DHS’s severely lim-
    ited resources are systematically directed to its highest priorities across a
    large and diverse agency, as well as ensuring consistency in the admin-
    istration of the removal system. The proposed policy’s identification of
    categories of aliens who constitute removal priorities is also consistent
    with the categorical nature of Congress’s instruction to prioritize the
    removal of criminal aliens in the DHS Appropriations Act.
    51
    
    38 Op. O.L.C. 39
     (2014)
    And, significantly, the proposed policy does not identify any category
    of removable aliens whose removal may not be pursued under any cir-
    cumstances. Although the proposed policy limits the discretion of immi-
    gration officials to expend resources to remove non-priority aliens, it does
    not eliminate that discretion entirely. It directs immigration officials to
    use their resources to remove aliens in a manner “commensurate with the
    level of prioritization identified,” but (as noted above) it does not “prohib-
    it or discourage the apprehension, detention, or removal of aliens unlaw-
    fully in the United States who are not identified as priorities.” Johnson
    Prioritization Memorandum at 5. Instead, it authorizes the removal of
    even non-priority aliens if, in the judgment of an ICE Field Office Direc-
    tor, “removing such an alien would serve an important federal interest,” a
    standard the policy leaves open-ended. 
    Id.
     Accordingly, the policy pro-
    vides for case-by-case determinations about whether an individual alien’s
    circumstances warrant the expenditure of removal resources, employing a
    broad standard that leaves ample room for the exercise of individualized
    discretion by responsible officials. For these reasons, the proposed policy
    avoids the difficulties that might be raised by a more inflexible prioritiza-
    tion policy and dispels any concern that DHS has either undertaken to
    rewrite the immigration laws or abdicated its statutory responsibilities
    with respect to non-priority aliens. 4
    4 In Crane v. Napolitano, a district court recently concluded in a non-precedential
    opinion that the INA “mandates the initiation of removal proceedings whenever an
    immigration officer encounters an illegal alien who is not ‘clearly and beyond a doubt
    entitled to be admitted.’” No. 3:12-cv-03247-O, 
    2013 WL 1744422
    , at *5 (N.D. Tex. Apr.
    23, 2013) (quoting 
    8 U.S.C. § 1225
    (b)(2)(A)). The court later dismissed the case for lack
    of jurisdiction. See Crane v. Napolitano, No. 3:12-cv-03247-O, 
    2013 WL 8211660
    , at *4
    (N.D. Tex. July 31, 2013). Although the opinion lacks precedential value, we have
    nevertheless considered whether, as it suggests, the text of the INA categorically foreclos-
    es the exercise of enforcement discretion with respect to aliens who have not been formal-
    ly admitted. The district court’s conclusion is, in our view, inconsistent with the Supreme
    Court’s reading of the INA as permitting immigration officials to exercise enforcement
    discretion at any stage of the removal process, including when deciding whether to initiate
    removal proceedings against a particular alien. See Arizona, 
    132 S. Ct. at 2499
    ; Am.-Arab
    Anti-Discrim. Comm., 
    525 U.S. at
    483–84. It is also difficult to square with authority
    holding that the presence of mandatory language in a statute, standing alone, does not
    necessarily limit the Executive Branch’s enforcement discretion. See, e.g., Chaney, 470
    52
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    II.
    We turn next to the permissibility of DHS’s proposed deferred action
    programs for certain aliens who are parents of U.S. citizens, lawful per-
    manent residents (“LPRs”), or DACA recipients, and who are not removal
    priorities under the proposed policy discussed above. We begin by dis-
    cussing the history and current practice of deferred action. We then dis-
    cuss the legal authorities on which deferred action relies and identify legal
    principles against which the proposed use of deferred action can be evalu-
    ated. Finally, we turn to an analysis of the proposed deferred action pro-
    grams themselves, beginning with the program for parents of U.S. citizens
    and LPRs, and concluding with the program for parents of DACA recipi-
    ents.
    A.
    In immigration law, the term “deferred action” refers to an exercise of
    administrative discretion in which immigration officials temporarily defer
    the removal of an alien unlawfully present in the United States. Am.-Arab
    Anti-Discrim. Comm., 
    525 U.S. at
    484 (citing 6 Charles Gordon et al.,
    Immigration Law and Procedure § 72.03[2][h] (1998)); see USCIS,
    Standard Operating Procedures for Handling Deferred Action Requests
    at USCIS Field Offices at 3 (2012) (“USCIS SOP”); INS Operating
    Instructions § 103.1(a)(1)(ii) (1977). It is one of a number of forms of
    discretionary relief—in addition to such statutory and non-statutory
    measures as parole, temporary protected status, deferred enforced depar-
    ture, and extended voluntary departure—that immigration officials have
    used over the years to temporarily prevent the removal of undocumented
    aliens. 5
    U.S. at 835; Inmates of Attica Corr. Facility v. Rockefeller, 
    477 F.2d 375
    , 381 (2d Cir.
    1973).
    5 Parole is available to aliens by statute “for urgent humanitarian reasons or significant
    public benefit.” 
    8 U.S.C. § 1182
    (d)(5)(A). Among other things, parole gives aliens the
    ability to adjust their status without leaving the United States if they are otherwise eligible
    for adjustment of status, see 
    id.
     § 1255(a), and may eventually qualify them for federal
    means-tested benefits, see id. §§ 1613, 1641(b)(4). Temporary protected status is availa-
    ble to nationals of designated foreign states affected by armed conflicts, environmental
    disasters, and other extraordinary conditions. Id. § 1254a. Deferred enforced departure,
    53
    
    38 Op. O.L.C. 39
     (2014)
    The practice of granting deferred action dates back several decades.
    For many years after the INA was enacted, INS exercised prosecutorial
    discretion to grant “non-priority” status to removable aliens who pre-
    sented “appealing humanitarian factors.” Letter for Leon Wildes from
    E.A. Loughran, Associate Commissioner, INS at 2 (July 16, 1973)
    (defining a “non-priority case” as “one in which the Service in the
    exercise of discretion determines that adverse action would be uncon-
    scionable because of appealing humanitarian factors”); see INS Operat-
    ing Instructions § 103.1(a)(1)(ii) (1962). This form of administrative
    discretion was later termed “deferred action.” Am.-Arab Anti-Discrim.
    Comm., 
    525 U.S. at 484
    ; see INS Operating Instructions § 103.1(a)(1)(ii)
    (1977) (instructing immigration officers to recommend deferred action
    whenever “adverse action would be unconscionable because of the exist-
    ence of appealing humanitarian factors”).
    which “has no statutory basis” but rather is an exercise of “the President’s constitutional
    powers to conduct foreign relations,” may be granted to nationals of appropriate foreign
    states. USCIS, Adjudicator’s Field Manual § 38.2(a) (2014). Extended voluntary depar-
    ture was a remedy derived from the voluntary departure statute, which, before its amend-
    ment in 1996, permitted the Attorney General to make a finding of removability if an
    alien agreed to voluntarily depart the United States, without imposing a time limit for the
    alien’s departure. See 
    8 U.S.C. §§ 1252
    (b), 1254(e) (1988 & Supp. II 1990); cf. 8 U.S.C.
    § 1229c (current provision of the INA providing authority to grant voluntary departure,
    but limiting such grants to 120 days). Some commentators, however, suggested that
    extended voluntary departure was in fact a form of “discretionary relief formulated
    administratively under the Attorney General’s general authority for enforcing immigration
    law.” Sharon Stephan, Cong. Research Serv., 85-599 EPW, Extended Voluntary De-
    parture and Other Grants of Blanket Relief from Deportation at 1 (Feb. 23, 1985). It
    appears that extended voluntary departure is no longer used following enactment of the
    Immigration Act of 1990, which established the temporary protected status program. See
    U.S. Citizenship and Immigration Services Fee Schedule, 
    75 Fed. Reg. 33,446
    , 33,457
    (June 11, 2010) (proposed rule) (noting that “since 1990 neither the Attorney General nor
    the Secretary have designated a class of aliens for nationality-based ‘extended voluntary
    departure,’ and there no longer are aliens in the United States benefiting from such a
    designation,” but noting that deferred enforced departure is still used); H.R. Rep. No. 102-
    123, at 2 (1991) (indicating that in establishing temporary protected status, Congress was
    “codif [ying] and supersed[ing]” extended voluntary departure). See generally Andorra

    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    Although the practice of granting deferred action “developed without
    express statutory authorization,” it has become a regular feature of the
    immigration removal system that has been acknowledged by both Con-
    gress and the Supreme Court. Am.-Arab Anti-Discrim. Comm., 
    525 U.S. at 484
     (internal quotation marks omitted); see 
    id. at 485
     (noting that a
    congressional enactment limiting judicial review of decisions “to com-
    mence proceedings, adjudicate cases, or execute removal orders against
    any alien under [the INA]” in 
    8 U.S.C. § 1252
    (g) “seems clearly de-
    signed to give some measure of protection to ‘no deferred action’ deci-
    sions and similar discretionary determinations”); see also, e.g., 
    8 U.S.C. § 1154
    (a)(1)(D)(i)(II), (IV) (providing that certain individuals are “eligi-
    ble for deferred action”). Deferred action “does not confer any immigra-
    tion status”—i.e., it does not establish any enforceable legal right to
    remain in the United States—and it may be revoked by immigration
    authorities at their discretion. USCIS SOP at 3, 7. Assuming it is not
    revoked, however, it represents DHS’s decision not to seek the alien’s
    removal for a specified period of time.
    Under longstanding regulations and policy guidance promulgated
    pursuant to statutory authority in the INA, deferred action recipients
    may receive two additional benefits. First, relying on DHS’s statutory
    authority to authorize certain aliens to work in the United States, DHS
    regulations permit recipients of deferred action to apply for work author-
    ization if they can demonstrate an “economic necessity for employ-
    ment.” 8 C.F.R. § 274a.12(c)(14); see 8 U.S.C. § 1324a(h)(3) (defining
    an “unauthorized alien” not entitled to work in the United States as an
    alien who is neither an LPR nor “authorized to be . . . employed by [the
    INA] or by the Attorney General [now the Secretary of Homeland Secu-
    rity]”). Second, DHS has promulgated regulations and issued policy
    guidance providing that aliens who receive deferred action will tempo-
    rarily cease accruing “unlawful presence” for purposes of 
    8 U.S.C. § 1182
    (a)(9)(B)(i) and (a)(9)(C)(i)(I).

    Act at 42 (May 6, 2009) (“USCIS Consolidation of Guidance”) (noting

    deferred action”); see 
    8 U.S.C. § 1182
    (a)(9)(B)(ii) (providing that an
    alien is “unlawfully present” if, among other things, he “is present in the
    United States after the expiration of the period of stay authorized by the
    Attorney General”). 6
    Immigration officials today continue to grant deferred action in indi-
    vidual cases for humanitarian and other purposes, a practice we will refer
    to as “ad hoc deferred action.” Recent USCIS guidance provides that
    personnel may recommend ad hoc deferred action if they “encounter cases
    during [their] normal course of business that they feel warrant deferred
    action.” USCIS SOP at 4. An alien may also apply for ad hoc deferred
    action by submitting a signed, written request to USCIS containing “[a]n
    explanation as to why he or she is seeking deferred action” along with
    supporting documentation, proof of identity, and other records. Id. at 3.
    For decades, INS and later DHS have also implemented broader pro-
    grams that make discretionary relief from removal available for particular
    classes of aliens. In many instances, these agencies have made such
    broad-based relief available through the use of parole, temporary protect-
    ed status, deferred enforced departure, or extended voluntary departure.
    For example, from 1956 to 1972, INS implemented an extended voluntary
    departure program for physically present aliens who were beneficiaries of
    approved visa petitions—known as “Third Preference” visa petitions—
    relating to a specific class of visas for Eastern Hemisphere natives. See
    United States ex rel. Parco v. Morris, 
    426 F. Supp. 976
    , 979–80 (E.D. Pa.
    1977). Similarly, for several years beginning in 1978, INS granted ex-
    tended voluntary departure to nurses who were eligible for H-1 visas.
    Voluntary Departure for Out-of-Status Nonimmigrant H-1 Nurses, 
    43 Fed. Reg. 2776
    , 2776 (Jan. 19, 1978). In addition, in more than two dozen
    instances dating to 1956, INS and later DHS granted parole, temporary
    protected status, deferred enforced departure, or extended voluntary
    departure to large numbers of nationals of designated foreign states.
    6 Section 1182(a)(9)(B)(i) imposes three- and ten-year bars on the admission of aliens
    (other than aliens admitted to permanent residence) who departed or were removed from
    the United States after periods of unlawful presence of between 180 days and one year, or
    one year or more. Section 1182(a)(9)(C)(i)(I) imposes an indefinite bar on the admission
    of any alien who, without being admitted, enters or attempts to reenter the United States
    after previously having been unlawfully present in the United States for an aggregate
    period of more than one year.

    ED206779, Review of U.S. Refugee Resettlement Programs and Policies
    at 9, 12–14 (1980). And in 1990, INS implemented a “Family Fairness”
    program that authorized granting extended voluntary departure and work
    authorization to the estimated 1.5 million spouses and children of aliens
    who had been granted legal status under the Immigration Reform and
    Control Act of 1986 (“IRCA”), Pub. L. No. 99-603, 
    100 Stat. 3359

    Departure Under 8 CFR 242.5 for the Ineligible Spouses and Children of
    Legalized Aliens (Feb. 2, 1990) (“Family Fairness Memorandum”); see
    also CRS Immigration Report at 10.
    On at least five occasions since the late 1990s, INS and later DHS have
    also made discretionary relief available to certain classes of aliens through
    the use of deferred action:
    1. Deferred Action for Battered Aliens Under the Violence Against
    Women Act. INS established a class-based deferred action program in
    1997 for the benefit of self-petitioners under the Violence Against
    Women Act of 1994 (“VAWA”), Pub. L. No. 103-322, tit. IV, 
    108 Stat. 1796
    , 1902. VAWA authorized certain aliens who have been abused by
    U.S. citizen or LPR spouses or parents to self-petition for lawful immi-
    gration status, without having to rely on their abusive family members
    to petition on their behalf.

    8 U.S.C. § 1154
    (a)(1)(A)(iii)–(iv), (vii)). The INS program required
    immigration officers who approved a VAWA self-petition to assess, “on
    a case-by-case basis, whether to place the alien in deferred action status”
    while the alien waited for a visa to become available. Memorandum for
    Regional Directors et al., INS, from Paul W. Virtue, Acting Executive
    Associate Commissioner, INS, Re: Supplemental Guidance on Battered
    Alien Self-Petitioning Process and Related Issues at 3 (May 6, 1997).
    INS noted that “[b]y their nature, VAWA cases generally possess factors
    that warrant consideration for deferred action.” 
    Id.
     But because “[i]n an
    unusual case, there may be factors present that would militate against
    deferred action,” the agency instructed officers that requests for deferred
    action should still “receive individual scrutiny.”

     In 2000, INS report-
    ed to Congress that, because of this program, no approved VAWA self-
    petitioner had been removed from the country. See Battered Women

    2. Deferred Action for T and U Visa Applicants. Several years later,
    INS instituted a similar deferred action program for applicants for
    nonimmigrant status or visas made available under the Victims of Traf-
    ficking and Violence Protection Act of 2000 (“VTVPA”), Pub. L. No.
    106-386, 
    114 Stat. 1464
    . That Act created two new nonimmigrant classi-
    fications: a “T visa” available to victims of human trafficking and their
    family members, and a “U visa” for victims of certain other crimes and
    their family members. 
    Id.

    8 U.S.C. § 1101
    (a)(15)(T)(i), (U)(i)). In 2001, INS issued a memorandum directing
    immigration officers to locate “possible victims in the above categories,”
    and to use “[e]xisting authority and mechanisms such as parole, deferred
    action, and stays of removal” to prevent those victims’ removal “until
    they have had the opportunity to avail themselves of the provisions of the
    VTVPA.” Memorandum for Michael A. Pearson, Executive Associate

    3. Deferred Action for Foreign Students Affected by Hurricane
    Katrina. As a consequence of the devastation caused by Hurricane
    Katrina in 2005, several thousand foreign students became temporarily
    unable to satisfy the requirements for maintaining their lawful status as
    F-1 nonimmigrant students, which include “pursuit of a ‘full course of
    study.’” USCIS, Interim Relief for Certain Foreign Academic Students

    that it would grant deferred action to these students “based on the fact
    that [their] failure to maintain status is directly due to Hurricane Katri-
    na.” Id. at 7. To apply for deferred action under this program, students
    were required to send a letter substantiating their need for deferred ac-
    tion, along with an application for work authorization. Press Release,

    4. Deferred Action for Widows and Widowers of U.S. Citizens. In
    2009, DHS implemented a deferred action program for certain widows
    and widowers of U.S. citizens. USCIS explained that “no avenue of
    immigration relief exists for the surviving spouse of a deceased U.S.
    citizen if the surviving spouse and the U.S. citizen were married less than
    2 years at the time of the citizen’s death” and USCIS had not yet adjudi-
    cated a visa petition on the spouse’s behalf. Memorandum for Field Lead-

    concerns arising from cases involving surviving spouses of U.S. citizens,”
    USCIS issued guidance permitting covered surviving spouses and “their
    qualifying children who are residing in the United States” to apply for
    deferred action. Id. at 2, 6. USCIS clarified that such relief would not be
    automatic, but rather would be unavailable in the presence of, for exam-
    ple, “serious adverse factors, such as national security concerns, signifi-
    cant immigration fraud, commission of other crimes, or public safety
    reasons.” Id. at 6. 7
    5. Deferred Action for Childhood Arrivals. Announced by DHS in
    2012, DACA makes deferred action available to “certain young people
    who were brought to this country as children” and therefore “[a]s a gen-
    eral matter . . . lacked the intent to violate the law.” Memorandum for

    2012) (“Napolitano Memorandum”). An alien is eligible for DACA if she
    was under the age of 31 when the program began; arrived in the United
    States before the age of 16; continuously resided in the United States for
    at least 5 years immediately preceding June 15, 2012; was physically
    present on June 15, 2012; satisfies certain educational or military service
    requirements; and neither has a serious criminal history nor “poses a
    threat to national security or public safety.” See id. DHS evaluates appli-

    surviving spouse guidance “obsolete,” USCIS withdrew its earlier guidance and treated all
    pending applications for deferred action as visa petitions. See Memorandum for Executive

    Congress has long been aware of the practice of granting deferred ac-
    tion, including in its categorical variety, and of its salient features; and it
    has never acted to disapprove or limit the practice. 9 On the contrary, it
    has enacted several pieces of legislation that have either assumed that
    deferred action would be available in certain circumstances, or expressly
    directed that deferred action be extended to certain categories of aliens.
    For example, as Congress was considering VAWA reauthorization
    8 Before DACA was announced, our Office was consulted about whether such a pro-
    gram would be legally permissible. As we orally advised, our preliminary view was that
    such a program would be permissible, provided that immigration officials retained
    discretion to evaluate each application on an individualized basis. We noted that immigra-
    tion officials typically consider factors such as having been brought to the United States
    as a child in exercising their discretion to grant deferred action in individual cases. We
    explained, however, that extending deferred action to individuals who satisfied these and
    other specified criteria on a class-wide basis would raise distinct questions not implicated
    by ad hoc grants of deferred action. We advised that it was critical that, like past policies
    that made deferred action available to certain classes of aliens, the DACA program
    require immigration officials to evaluate each application for deferred action on a case-
    by-case basis, rather than granting deferred action automatically to all applicants who
    satisfied the threshold eligibility criteria. We also noted that, although the proposed
    program was predicated on humanitarian concerns that appeared less particularized and
    acute than those underlying certain prior class-wide deferred action programs, the con-
    cerns animating DACA were nonetheless consistent with the types of concerns that have
    customarily guided the exercise of immigration enforcement discretion.
    9 Congress has considered legislation that would limit the practice of granting deferred
    action, but it has never enacted such a measure. In 2011, a bill was introduced in both the
    House and the Senate that would have temporarily suspended DHS’s authority to grant
    deferred action except in narrow circumstances. See H.R. 2497, 112th Cong. (2011);
    S. 1380, 112th Cong. (2011). Neither chamber, however, voted on the bill. This year, the
    House passed a bill that purported to bar any funding for DACA or other class-wide
    deferred action programs, H.R. 5272, 113th Cong. (2014), but the Senate has not consid-
    ered the legislation. Because the Supreme Court has instructed that unenacted legislation
    is an unreliable indicator of legislative intent, see Red Lion Broad. Co. v. FCC, 
    395 U.S. 367
    , 381 n.11 (1969), we do not draw any inference regarding congressional policy from
    these unenacted bills.

    legislation in 2000, INS officials testified before Congress about their
    deferred action program for VAWA self-petitioners, explaining that
    “[a]pproved [VAWA] self-petitioners are placed in deferred action sta-
    tus,” such that “[n]o battered alien who has filed a[n approved] self
    petition . . . has been deported.” H.R. 3083 Hearings at 43. Congress
    responded by not only acknowledging but also expanding the deferred
    action program in the 2000 VAWA reauthorization legislation, providing
    that children who could no longer self-petition under VAWA because
    they were over the age of 21 would nonetheless be “eligible for deferred
    action and work authorization.” VTVPA § 1503(d)(2), 114 Stat. at 1522
    (codified at 
    8 U.S.C. § 1154
    (a)(1)(D)(i)(II), (IV)). 10
    Congress demonstrated a similar awareness of INS’s (and later DHS’s)
    deferred action program for bona fide T and U visa applicants. As dis-
    cussed above, that program made deferred action available to nearly all
    individuals who could make a prima facie showing of eligibility for a T or
    U visa. In 2008 legislation, Congress authorized DHS to “grant . . . an
    administrative stay of a final order of removal” to any such individual.
    William Wilberforce Trafficking Victims Protection Reauthorization Act
    of 2008, Pub. L. No. 110-457, § 204, 
    122 Stat. 5044
    , 5060 (codified at
    
    8 U.S.C. § 1227
    (d )(1)). Congress further clarified that “[t]he denial of a
    request for an administrative stay of removal under this subsection shall
    not preclude the alien from applying for . . . deferred action.” 
    Id.
     It also
    directed DHS to compile a report detailing, among other things, how long
    DHS’s “specially trained [VAWA] Unit at the [USCIS] Vermont Service
    Center” took to adjudicate victim-based immigration applications for
    “deferred action,” along with “steps taken to improve in this area.”

    Id.
     § 814(b) (codified at 
    8 U.S.C. § 1154

    Act’s sponsors explained that while this provision was intended to “give[] DHS statutory
    authority to grant work authorization . . . without having to rely upon deferred action . . .
    [t]he current practice of granting deferred action to approved VAWA self-petitioners
    should continue.” 151 Cong. Rec. 29,334 (2005) (statement of Rep. Conyers).

    filing.” 154 Cong. Rec. 24,603 (2008).
    In addition, in other enactments, Congress has specified that certain
    classes of individuals should be made “eligible for deferred action.” These
    classes include certain immediate family members of LPRs who were
    killed on September 11, 2001, USA PATRIOT Act of 2001, Pub. L. No.
    107-56, § 423(b), 
    115 Stat. 272
    , 361, and certain immediate family mem-
    bers of certain U.S. citizens killed in combat, National Defense Authori-
    zation Act for Fiscal Year 2004, Pub. L. No. 108-136, § 1703(c)–(d), 
    117 Stat. 1392
    , 1694 (2003). In the same legislation, Congress made these
    individuals eligible to obtain lawful status as “family-sponsored immi-
    grant[s]” or “immediate relative[s]” of U.S. citizens. Pub. L. No. 107-56,
    § 423(b), 115 Stat. at 361; Pub. L. No. 108-136, § 1703(c)(1)(A), 117
    Stat. at 1694. See generally Scialabba v. Cuellar de Osorio, 
    134 S. Ct. 2191
    , 2197 (2014) (plurality opinion) (explaining which aliens typically
    qualify as family-sponsored immigrants or immediate relatives).
    Finally, Congress acknowledged the practice of granting deferred ac-
    tion in the REAL ID Act of 2005, Pub. L. No. 109-13, div. B, 
    119 Stat. 231
    , 302 (codified at 
    49 U.S.C. § 30301
     note), which makes a state-issued
    driver’s license or identification card acceptable for federal purposes only
    if the state verifies, among other things, that the card’s recipient has
    “[e]vidence of [l]awful [s]tatus.” Congress specified that, for this purpose,
    acceptable evidence of lawful status includes proof of, among other
    things, citizenship, lawful permanent or temporary residence, or “ap-
    proved deferred action status.” 
    Id.
     § 202(c)(2)(B)(viii).
    B.
    The practice of granting deferred action, like the practice of setting en-
    forcement priorities, is an exercise of enforcement discretion rooted in
    DHS’s authority to enforce the immigration laws and the President’s duty
    to take care that the laws are faithfully executed. It is one of several
    mechanisms by which immigration officials, against a backdrop of limited
    enforcement resources, exercise their “broad discretion” to administer the
    removal system—and, more specifically, their discretion to determine
    whether “it makes sense to pursue removal” in particular circumstances.
    Arizona, 
    132 S. Ct. at 2499
    .
    63
    
    38 Op. O.L.C. 39
     (2014)
    Deferred action, however, differs in at least three respects from more
    familiar and widespread exercises of enforcement discretion. First, unlike
    (for example) the paradigmatic exercise of prosecutorial discretion in a
    criminal case, the conferral of deferred action does not represent a deci-
    sion not to prosecute an individual for past unlawful conduct; it instead
    represents a decision to openly tolerate an undocumented alien’s contin-
    ued presence in the United States for a fixed period (subject to revocation
    at the agency’s discretion). Second, unlike most exercises of enforcement
    discretion, deferred action carries with it benefits in addition to non-
    enforcement itself; specifically, the ability to seek employment authori-
    zation and suspension of unlawful presence for purposes of 
    8 U.S.C. § 1182
    (a)(9)(B)(i) and (a)(9)(C)(i)(I). Third, class-based deferred action
    programs, like those for VAWA recipients and victims of Hurricane
    Katrina, do not merely enable individual immigration officials to select
    deserving beneficiaries from among those aliens who have been identi-
    fied or apprehended for possible removal—as is the case with ad hoc
    deferred action—but rather set forth certain threshold eligibility criteria
    and then invite individuals who satisfy these criteria to apply for deferred
    action status.
    While these features of deferred action are somewhat unusual among
    exercises of enforcement discretion, the differences between deferred
    action and other exercises of enforcement discretion are less significant
    than they might initially appear. The first feature—the toleration of an
    alien’s continued unlawful presence—is an inevitable element of almost
    any exercise of discretion in immigration enforcement. Any decision not
    to remove an unlawfully present alien—even through an exercise of
    routine enforcement discretion—necessarily carries with it a tacit ac-
    knowledgment that the alien will continue to be present in the United
    States without legal status. Deferred action arguably goes beyond such
    tacit acknowledgment by expressly communicating to the alien that his or
    her unlawful presence will be tolerated for a prescribed period of time.
    This difference is not, in our view, insignificant. But neither does it fun-
    damentally transform deferred action into something other than an exer-
    cise of enforcement discretion: As we have previously noted, deferred
    action confers no lawful immigration status, provides no path to lawful
    permanent residence or citizenship, and is revocable at any time in the
    agency’s discretion.
    64
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    With respect to the second feature, the additional benefits deferred ac-
    tion confers—the ability to apply for work authorization and the tolling
    of unlawful presence—do not depend on background principles of agen-
    cy discretion under DHS’s general immigration authorities or the Take
    Care Clause at all, but rather depend on independent and more specific
    statutory authority rooted in the text of the INA. The first of those au-
    thorities, DHS’s power to prescribe which aliens are authorized to work
    in the United States, is grounded in 8 U.S.C. § 1324a(h)(3), which de-
    fines an “unauthorized alien” not entitled to work in the United States as
    an alien who is neither an LPR nor “authorized to be . . . employed by
    [the INA] or by the Attorney General [now the Secretary of Homeland
    Security].” This statutory provision has long been understood to recog-
    nize the authority of the Secretary (and the Attorney General before him)
    to grant work authorization to particular classes of aliens. See 8 C.F.R.
    § 274a.12; see also Perales v. Casillas, 
    903 F.2d 1043
    , 1048–50 (5th Cir.
    1990) (describing the authority recognized by section 1324a(h)(3) as
    “permissive” and largely “unfettered”). 11 Although the INA requires the
    11 Section 1324a(h)(3) was enacted in 1986 as part of IRCA. Before then, the INA con-
    tained no provisions comprehensively addressing the employment of aliens or expressly
    delegating the authority to regulate the employment of aliens to a responsible federal
    agency. INS assumed the authority to prescribe the classes of aliens authorized to work in
    the United States under its general responsibility to administer the immigration laws. In
    1981, INS promulgated regulations codifying its existing procedures and criteria for
    granting employment authorization. See Employment Authorization to Aliens in the
    United States, 
    46 Fed. Reg. 25,079
    , 25,080–81 (May 5, 1981) (citing 
    8 U.S.C. § 1103
    (a)).
    Those regulations permitted certain categories of aliens who lacked lawful immigration
    status, including deferred action recipients, to apply for work authorization under certain
    circumstances. 
    8 C.F.R. § 109.1
    (b)(7) (1982). In IRCA, Congress introduced a “compre-
    hensive scheme prohibiting the employment of illegal aliens in the United States,”
    Hoffman Plastic Compounds, Inc. v. NLRB, 
    535 U.S. 137
    , 147 (2002), to be enforced
    primarily through criminal and civil penalties on employers who knowingly employ an
    “unauthorized alien.” As relevant here, Congress defined an “unauthorized alien” barred
    from employment in the United States as an alien who “is not . . . either (A) an alien
    lawfully admitted for permanent residence, or (B) authorized to be so employed by this
    chapter or by the Attorney General.” 8 U.S.C. § 1324a(h)(3) (emphasis added). Shortly
    after IRCA was enacted, INS denied a petition to rescind its employment authorization
    regulation, rejecting an argument that “the phrase ‘authorized to be so employed by this
    Act or the Attorney General’ does not recognize the Attorney General’s authority to grant
    work authorization except to those aliens who have already been granted specific authori-
    zation by the Act.” Employment Authorization; Classes of Aliens Eligible,

    itations on the Secretary’s authority to grant work authorization to other
    classes of aliens. Further, and notably, additional provisions of the INA
    expressly contemplate that the Secretary may grant work authorization to
    aliens lacking lawful immigration status—even those who are in active
    removal proceedings or, in certain circumstances, those who have already
    received final orders of removal. See 
    id.
     § 1226(a)(3) (permitting the
    Secretary to grant work authorization to an otherwise work-eligible alien
    who has been arrested and detained pending a decision whether to re-
    move the alien from the United States); id. § 1231(a)(7) (permitting the
    Secretary under certain narrow circumstances to grant work authorization
    to aliens who have received final orders of removal). Consistent with
    these provisions, the Secretary has long permitted certain additional
    classes of aliens who lack lawful immigration status to apply for work
    authorization, including deferred action recipients who can demonstrate
    an economic necessity for employment. See 8 C.F.R. § 274a.12(c)(14);
    see also id. § 274a.12(c)(8) (applicants for asylum), (c)(10) (applicants
    for cancellation of removal); supra note 11 (discussing 1981 regulations).
    The Secretary’s authority to suspend the accrual of unlawful presence
    of deferred action recipients is similarly grounded in the INA. The rele-
    vant statutory provision treats an alien as “unlawfully present” for pur-
    poses of 
    8 U.S.C. § 1182
    (a)(9)(B)(i) and (a)(9)(C)(i)(I) if he “is present in
    the United States after the expiration of the period of stay authorized by
    the Attorney General.” 
    8 U.S.C. § 1182
    (a)(9)(B)(ii). That language con-
    templates that the Attorney General (and now the Secretary) may author-
    ize an alien to stay in the United States without accruing unlawful pres-
    46,092, 46,093 (Dec. 4, 1987). Because the same statutory phrase refers both to aliens
    authorized to be employed by the INA and aliens authorized to be employed by the
    Attorney General, INS concluded that the only way to give effect to both references is to
    conclude “that Congress, being fully aware of the Attorney General’s authority to prom-
    ulgate regulations, and approving of the manner in which he has exercised that authority
    in this matter, defined ‘unauthorized alien’ in such fashion as to exclude aliens who have
    been authorized employment by the Attorney General through the regulatory process, in
    addition to those who are authorized employment by statute.” Id.; see Commodity Futures
    Trading Comm’n v. Schor, 
    478 U.S. 833
    , 844 (1986) (stating that “considerable weight
    must be accorded” an agency’s “contemporaneous interpretation of the statute it is en-
    trusted to administer”).

    ferred action. See

    The final unusual feature of deferred action programs is particular to
    class-based programs. The breadth of such programs, in combination with
    the first two features of deferred action, may raise particular concerns
    about whether immigration officials have undertaken to substantively
    change the statutory removal system rather than simply adapting its appli-
    cation to individual circumstances. But the salient feature of class-based
    programs—the establishment of an affirmative application process with
    threshold eligibility criteria—does not in and of itself cross the line be-
    tween executing the law and rewriting it. Although every class-wide
    deferred action program that has been implemented to date has established
    certain threshold eligibility criteria, each program has also left room for
    case-by-case determinations, giving immigration officials discretion to
    deny applications even if the applicant fulfills all of the program criteria.
    See supra pp. 57–61. Like the establishment of enforcement priorities
    discussed in Part I, the establishment of threshold eligibility criteria can
    serve to avoid arbitrary enforcement decisions by individual officers,
    thereby furthering the goal of ensuring consistency across a large agency.
    The guarantee of individualized, case-by-case review helps avoid poten-
    tial concerns that, in establishing such eligibility criteria, the Executive is
    attempting to rewrite the law by defining new categories of aliens who are
    automatically entitled to particular immigration relief. See Crowley Car-
    ibbean Transp., 
    37 F.3d at
    676–77; see also Chaney, 
    470 U.S. at
    833 n.4.
    Furthermore, while permitting potentially eligible individuals to apply for
    an exercise of enforcement discretion is not especially common, many law
    enforcement agencies have developed programs that invite violators of the
    law to identify themselves to the authorities in exchange for leniency. 12
    12 For example, since 1978, the Department of Justice’s Antitrust Division has imple-
    mented a “leniency program” under which a corporation that reveals an antitrust conspira-
    cy in which it participated may receive a conditional promise that it will not be prosecut-
    ed. See Dep’t of Justice, Frequently Asked Questions Regarding the Antitrust Division’s
    Leniency Program and Model Leniency Letters (Nov. 19, 2008), http://www.justice.gov/
    atr/public/criminal/239583.pdf (last visited Nov. 19, 2014); see also Internal Revenue
    67
    
    38 Op. O.L.C. 39
     (2014)
    Much as is the case with those programs, inviting eligible aliens to identi-
    fy themselves through an application process may serve the agency’s law
    enforcement interests by encouraging lower-priority individuals to identi-
    fy themselves to the agency. In so doing, the process may enable the
    agency to better focus its scarce resources on higher enforcement priori-
    ties.
    Apart from the considerations just discussed, perhaps the clearest indi-
    cation that these features of deferred action programs are not per se im-
    permissible is the fact that Congress, aware of these features, has repeat-
    edly enacted legislation appearing to endorse such programs. As discussed
    above, Congress has not only directed that certain classes of aliens be
    made eligible for deferred action programs—and in at least one instance,
    in the case of VAWA beneficiaries, directed the expansion of an existing
    program—but also ranked evidence of approved deferred action status as
    evidence of “lawful status” for purposes of the REAL ID Act. These
    enactments strongly suggest that when DHS in the past has decided to
    grant deferred action to an individual or class of individuals, it has been
    acting in a manner consistent with congressional policy “‘rather than
    embarking on a frolic of its own.’” United States v. Riverside Bayview

    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    Congress’s apparent endorsement of certain deferred action programs
    does not mean, of course, that a deferred action program can be lawfully
    extended to any group of aliens, no matter its characteristics or its scope,
    and no matter the circumstances in which the program is implemented.
    Because deferred action, like the prioritization policy discussed above, is
    an exercise of enforcement discretion rooted in the Secretary’s broad
    authority to enforce the immigration laws and the President’s duty to take
    care that the laws are faithfully executed, it is subject to the same four
    general principles previously discussed. See supra pp. 46–47. Thus, any
    expansion of deferred action to new classes of aliens must be carefully
    scrutinized to ensure that it reflects considerations within the agency’s
    expertise, and that it does not seek to effectively rewrite the laws to match
    the Executive’s policy preferences, but rather operates in a manner conso-
    nant with congressional policy expressed in the statute. See supra p. 46
    (citing Youngstown, 
    343 U.S. at 637
    , and Nat’l Ass’n of Home Builders,
    
    551 U.S. at 658
    ). Immigration officials cannot abdicate their statutory
    responsibilities under the guise of exercising enforcement discretion. See
    supra pp. 46–47 (citing Chaney, 
    470 U.S. at
    833 n.4). And any new
    deferred action program should leave room for individualized evaluation
    of whether a particular case warrants the expenditure of resources for
    enforcement. See supra p. 47 (citing Glickman, 
    96 F.3d at 1123
    , and
    Crowley Caribbean Transp., 
    37 F.3d at
    676–77).
    Furthermore, because deferred action programs depart in certain re-
    spects from more familiar and widespread exercises of enforcement
    discretion, particularly careful examination is needed to ensure that any
    proposed expansion of deferred action complies with these general princi-
    ples, so that the proposed program does not, in effect, cross the line be-
    tween executing the law and rewriting it. In analyzing whether the pro-
    posed programs cross this line, we will draw substantial guidance from
    Congress’s history of legislation concerning deferred action. In the ab-
    sence of express statutory guidance, the nature of deferred action pro-
    grams Congress has implicitly approved by statute helps to shed light on
    Congress’s own understandings about the permissible uses of deferred
    action. Those understandings, in turn, help to inform our consideration of
    whether the proposed deferred action programs are “faithful[]” to the
    statutory scheme Congress has enacted. U.S. Const. art. II, § 3.
    69
    
    38 Op. O.L.C. 39
     (2014)
    C.
    We now turn to the specifics of DHS’s proposed deferred action pro-
    grams. DHS has proposed implementing a policy under which an alien
    could apply for, and would be eligible to receive, deferred action if he or
    she: (1) is not an enforcement priority under DHS policy; (2) has continu-
    ously resided in the United States since before January 1, 2010; (3) is
    physically present in the United States both when DHS announces its
    program and at the time of application for deferred action; (4) has a child
    who is a U.S. citizen or LPR; and (5) presents “no other factors that, in
    the exercise of discretion, make[] the grant of deferred action inappropri-
    ate.” Johnson Deferred Action Memorandum at 4. You have also asked
    about the permissibility of a similar program that would be open to par-
    ents of children who have received deferred action under the DACA
    program. We first address DHS’s proposal to implement a deferred action
    program for the parents of U.S. citizens and LPRs, and then turn to the
    permissibility of the program for parents of DACA recipients in the next
    subsection.
    1.
    We begin by considering whether the proposed program for the parents
    of U.S. citizens and LPRs reflects considerations within the agency’s
    expertise. DHS has offered two justifications for the proposed program
    for the parents of U.S. citizens and LPRs. First, as noted above, severe
    resource constraints make it inevitable that DHS will not remove the vast
    majority of aliens who are unlawfully present in the United States. Con-
    sistent with Congress’s instruction, DHS prioritizes the removal of indi-
    viduals who have significant criminal records, as well as others who
    present dangers to national security, public safety, or border security. See
    supra pp. 50–51. Parents with longstanding ties to the country and who
    have no significant criminal records or other risk factors rank among the
    agency’s lowest enforcement priorities; absent significant increases in
    funding, the likelihood that any individual in that category will be deter-
    mined to warrant the expenditure of severely limited enforcement re-
    sources is very low. Second, DHS has explained that the program would
    serve an important humanitarian interest in keeping parents together with
    children who are lawfully present in the United States, in situations where
    70
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    such parents have demonstrated significant ties to community and family
    in this country. See Shahoulian E-mail.
    With respect to DHS’s first justification, the need to efficiently allocate
    scarce enforcement resources is a quintessential basis for an agency’s
    exercise of enforcement discretion. See Chaney, 
    470 U.S. at 831
    . Because,
    as discussed earlier, Congress has appropriated only a small fraction of
    the funds needed for full enforcement, DHS can remove no more than a
    small fraction of the individuals who are removable under the immigra-
    tion laws. See supra p. 49. The agency must therefore make choices about
    which violations of the immigration laws it will prioritize and pursue.
    And as Chaney makes clear, such choices are entrusted largely to the
    Executive’s discretion. 470 U.S. at 831.
    The deferred action program DHS proposes would not, of course, be
    costless. Processing applications for deferred action and its renewal re-
    quires manpower and resources. See Arizona, 
    132 S. Ct. at 2521
     (Scalia, J.,
    concurring in part and dissenting in part). But DHS has informed us that
    the costs of administering the proposed program would be borne almost
    entirely by USCIS through the collection of application fees. See Sha-
    houlian E-mail; see also 
    8 U.S.C. § 1356
    (m); 
    8 C.F.R. § 103.7
    (b)(1)(i)(C),
    (b)(1)(i)(HH). DHS has indicated that the costs of administering the
    deferred action program would therefore not detract in any significant
    way from the resources available to ICE and CBP—the enforcement arms
    of DHS—which rely on money appropriated by Congress to fund their
    operations. See Shahoulian E-mail. DHS has explained that, if anything,
    the proposed deferred action program might increase ICE’s and CBP’s
    efficiency by in effect using USCIS’s fee-funded resources to enable
    those enforcement divisions to more easily identify non-priority aliens
    and focus their resources on pursuing aliens who are strong candidates for
    removal. See 
    id.
     The proposed program, in short, might help DHS address
    its severe resource limitations, and at the very least likely would not
    exacerbate them. See 
    id.
    DHS does not, however, attempt to justify the proposed program solely
    as a cost-saving measure, or suggest that its lack of resources alone is
    sufficient to justify creating a deferred action program for the proposed
    class. Rather, as noted above, DHS has explained that the program would
    also serve a particularized humanitarian interest in promoting family unity
    by enabling those parents of U.S. citizens and LPRs who are not other-
    71
    
    38 Op. O.L.C. 39
     (2014)
    wise enforcement priorities and who have demonstrated community and
    family ties in the United States (as evidenced by the length of time they
    have remained in the country) to remain united with their children in the
    United States. Like determining how best to respond to resource con-
    straints, determining how to address such “human concerns” in the immi-
    gration context is a consideration that is generally understood to fall
    within DHS’s expertise. Arizona, 
    132 S. Ct. at 2499
    .
    This second justification for the program also appears consonant with
    congressional policy embodied in the INA. Numerous provisions of the
    statute reflect a particular concern with uniting aliens with close relatives
    who have attained lawful immigration status in the United States. See,
    e.g., Fiallo v. Bell, 
    430 U.S. 787
    , 795 n.6 (1977); INS v. Errico, 
    385 U.S. 214
    , 220 n.9 (1966) (“‘The legislative history of the Immigration and
    Nationality Act clearly indicates that the Congress . . . was concerned
    with the problem of keeping families of United States citizens and immi-
    grants united.’” (quoting H.R. Rep. No. 85-1199, at 7 (1957)). The INA
    provides a path to lawful status for the parents, as well as other immediate
    relatives, of U.S. citizens: U.S. citizens aged twenty-one or over may
    petition for parents to obtain visas that would permit them to enter and
    permanently reside in the United States, and there is no limit on the
    overall number of such petitions that may be granted. See 
    8 U.S.C. § 1151
    (b)(2)(A)(i); see also Cuellar de Osorio, 
    134 S. Ct. at
    2197–99
    (describing the process for obtaining a family-based immigrant visa). And
    although the INA contains no parallel provision permitting LPRs to peti-
    tion on behalf of their parents, it does provide a path for LPRs to become
    citizens, at which point they too can petition to obtain visas for their
    parents. See, e.g., 
    8 U.S.C. § 1427
    (a) (providing that aliens are generally
    eligible to become naturalized citizens after five years of lawful perma-
    nent residence); 
    id.
     § 1430(a) (alien spouses of U.S. citizens become
    eligible after three years of lawful permanent residence); Demore v. Kim,
    
    538 U.S. 510
    , 544 (2003). 13 Additionally, the INA empowers the Attorney
    13 The INA does permit LPRs to petition on behalf of their spouses and children even
    before they have attained citizenship. See 
    8 U.S.C. § 1153
    (a)(2). However, the exclusion
    of LPRs’ parents from this provision does not appear to reflect a congressional judgment
    that, until they attain citizenship, LPRs lack an interest in being united with their parents
    comparable to their interest in being united with their other immediate relatives. The
    distinction between parents and other relatives originated with a 1924 statute that exempt-
    72
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    General to cancel the removal of, and adjust to LPR status, aliens who
    have been physically present in the United States for a continuous period
    of not less than ten years, exhibit good moral character, have not been
    convicted of specified offenses, and have immediate relatives who are
    U.S. citizens or LPRs and who would suffer exceptional hardship from the
    alien’s removal. 8 U.S.C. § 1229b(b)(1). DHS’s proposal to focus on the
    parents of U.S. citizens and LPRs thus tracks a congressional concern,
    expressed in the INA, with uniting the immediate families of individuals
    who have permanent legal ties to the United States.
    At the same time, because the temporary relief DHS’s proposed pro-
    gram would confer to such parents is sharply limited in comparison to the
    benefits Congress has made available through statute, DHS’s proposed
    program would not operate to circumvent the limits Congress has placed
    on the availability of those benefits. The statutory provisions discussed
    above offer the parents of U.S. citizens and LPRs the prospect of perma-
    nent lawful status in the United States. The cancellation of removal
    provision, moreover, offers the prospect of receiving such status immedi-
    ately, without the delays generally associated with the family-based
    immigrant visa process. DHS’s proposed program, in contrast, would not
    grant the parents of U.S. citizens and LPRs any lawful immigration
    status, provide a path to permanent residence or citizenship, or otherwise
    confer any legally enforceable entitlement to remain in the United States.
    ed the wives and minor children of U.S. citizens from immigration quotas, gave “prefer-
    ence status”—eligibility for a specially designated pool of immigrant visas—to other
    relatives of U.S. citizens, and gave no favorable treatment to the relatives of LPRs.
    Immigration Act of 1924, Pub. L. No. 68-139, §§ 4(a), 6, 
    43 Stat. 153
    , 155–56. In 1928,
    Congress extended preference status to LPRs’ wives and minor children, reasoning that
    because such relatives would be eligible for visas without regard to any quota when their
    LPR relatives became citizens, granting preference status to LPRs’ wives and minor
    children would “hasten[]” the “family reunion.” S. Rep. No. 70-245, at 2 (1928); see Pub.
    Res. No. 70-61, 
    45 Stat. 1009
    , 1009–10 (1928). The special visa status for wives and
    children of LPRs thus mirrored, and was designed to complement, the special visa status
    given to wives and minor children of U.S. citizens. In 1965, Congress eliminated the basis
    on which the distinction had rested by exempting all “immediate relatives” of U.S.
    citizens, including parents, from numerical restrictions on immigration. Pub. L. No. 89-
    236, § 1, 
    79 Stat. 911
    , 911. But it did not amend eligibility for preference status for
    relatives of LPRs to reflect that change. We have not been able to discern any rationale
    for this omission in the legislative history or statutory text of the 1965 law.
    73
    
    38 Op. O.L.C. 39
     (2014)
    See USCIS SOP at 3. It is true that, as we have discussed, a grant of
    deferred action would confer eligibility to apply for and obtain work
    authorization, pursuant to the Secretary’s statutory authority to grant
    such authorization and the longstanding regulations promulgated there-
    under. See supra pp. 55, 65–66. But unlike the automatic employment
    eligibility that accompanies LPR status, see 8 U.S.C. § 1324a(h)(3), this
    authorization could be granted only on a showing of economic necessity,
    and would last only for the limited duration of the deferred action grant,
    see 8 C.F.R. § 274a.12(c)(14).
    The other salient features of the proposal are similarly consonant with
    congressional policy. The proposed program would focus on parents who
    are not enforcement priorities under the prioritization policy discussed
    above—a policy that, as explained earlier, comports with the removal
    priorities set by Congress. See supra pp. 50–51. The continuous residence
    requirement is likewise consistent with legislative judgments that extend-
    ed periods of continuous residence are indicative of strong family and
    community ties. See IRCA § 201(a), 100 Stat. at 3394 (codified as
    amended at 8 U.S.C. § 1255a(a)(2)) (granting lawful status to certain
    aliens unlawfully present in the United States since January 1, 1982); id.
    § 302(a) (codified as amended at 
    8 U.S.C. § 1160
    ) (granting similar relief
    to certain agricultural workers); H.R. Rep. No. 99-682, pt. 1, at 49 (1986)
    (stating that aliens present in the United States for five years “have be-
    come a part of their communities[,] . . . have strong family ties here which
    include U.S. citizens and lawful residents[,] . . . have built social networks
    in this country[, and] . . . have contributed to the United States in myriad
    ways”); S. Rep. No. 99-132, at 16 (1985) (deporting aliens who “have
    become well settled in this country” would be a “wasteful use of the
    Immigration and Naturalization Service’s limited enforcement re-
    sources”); see also Arizona, 
    132 S. Ct. at 2499
     (noting that “[t]he equities
    of an individual case” turn on factors “including whether the alien has . . .
    long ties to the community”).
    We also do not believe DHS’s proposed program amounts to an abdica-
    tion of its statutory responsibilities, or a legislative rule overriding the
    commands of the statute. As discussed earlier, DHS’s severe resource
    constraints mean that, unless circumstances change, it could not as a
    practical matter remove the vast majority of removable aliens present in
    the United States. The fact that the proposed program would defer the
    74
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    removal of a subset of these removable aliens—a subset that ranks near
    the bottom of the list of the agency’s removal priorities—thus does not,
    by itself, demonstrate that the program amounts to an abdication of DHS’s
    responsibilities. And the case-by-case discretion given to immigration
    officials under DHS’s proposed program alleviates potential concerns that
    DHS has abdicated its statutory enforcement responsibilities with respect
    to, or created a categorical, rule-like entitlement to immigration relief for,
    the particular class of aliens eligible for the program. An alien who meets
    all the criteria for deferred action under the program would receive de-
    ferred action only if he or she “present[ed] no other factors that, in the
    exercise of discretion,” would “make[] the grant of deferred action inap-
    propriate.” Johnson Deferred Action Memorandum at 4. The proposed
    policy does not specify what would count as such a factor; it thus leaves
    the relevant USCIS official with substantial discretion to determine
    whether a grant of deferred action is warranted. In other words, even if an
    alien is not a removal priority under the proposed policy discussed in
    Part I, has continuously resided in the United States since before Janu-
    ary 1, 2010, is physically present in the country, and is a parent of an LPR
    or a U.S. citizen, the USCIS official evaluating the alien’s deferred action
    application must still make a judgment, in the exercise of her discretion,
    about whether that alien presents any other factor that would make a grant
    of deferred action inappropriate. This feature of the proposed program
    ensures that it does not create a categorical entitlement to deferred action
    that could raise concerns that DHS is either impermissibly attempting to
    rewrite or categorically declining to enforce the law with respect to a
    particular group of undocumented aliens.
    Finally, the proposed deferred action program would resemble in mate-
    rial respects the kinds of deferred action programs Congress has implicitly
    approved in the past, which provides some indication that the proposal is
    consonant not only with interests reflected in immigration law as a gen-
    eral matter, but also with congressional understandings about the permis-
    sible uses of deferred action. As noted above, the program uses deferred
    action as an interim measure for a group of aliens to whom Congress has
    given a prospective entitlement to lawful immigration status. While Con-
    gress has provided a path to lawful status for the parents of U.S. citizens
    and LPRs, the process of obtaining that status “takes time.” Cuellar de
    Osorio, 
    134 S. Ct. at 2199
    . The proposed program would provide a mech-
    75
    
    38 Op. O.L.C. 39
     (2014)
    anism for families to remain together, depending on their circumstances,
    for some or all of the intervening period. 14 Immigration officials have on
    several occasions deployed deferred action programs as interim measures
    for other classes of aliens with prospective entitlements to lawful immi-
    gration status, including VAWA self-petitioners, bona fide T and U visa
    applicants, certain immediate family members of certain U.S. citizens
    killed in combat, and certain immediate family members of aliens killed
    on September 11, 2001. As noted above, each of these programs has
    received Congress’s implicit approval—and, indeed, in the case of
    VAWA self-petitioners, a direction to expand the program beyond its
    original bounds. See supra pp. 61–63. 15 In addition, much like these and
    14 DHS’s proposed program would likely not permit all potentially eligible parents to
    remain together with their children for the entire duration of the time until a visa is
    awarded. In particular, undocumented parents of adult citizens who are physically present
    in the country would be ineligible to adjust their status without first leaving the country if
    they had never been “inspected and admitted or paroled into the United States.” 
    8 U.S.C. § 1255
    (a) (permitting the Attorney General to adjust to permanent resident status certain
    aliens present in the United States if they become eligible for immigrant visas). They
    would thus need to leave the country to obtain a visa at a U.S. consulate abroad. See 
    id.
    § 1201(a); Cuellar de Osorio, 
    134 S. Ct. at
    2197–99. But once such parents left the
    country, they would in most instances become subject to the 3- or 10-year bar under
    
    8 U.S.C. § 1182
    (a)(9)(B)(i) and therefore unable to obtain a visa unless they remained
    outside the country for the duration of the bar. DHS’s proposed program would neverthe-
    less enable other families to stay together without regard to the 3- or 10-year bar. And
    even as to those families with parents who would become subject to that bar, the proposed
    deferred action program would have the effect of reducing the amount of time the family
    had to spend apart, and could enable them to adjust the timing of their separation accord-
    ing to, for example, their children’s needs for care and support.
    15 Several extended voluntary departure programs have been animated by a similar
    rationale, and the most prominent of these programs also received Congress’s implicit
    approval. In particular, as noted above, the Family Fairness policy, implemented in 1990,
    authorized granting extended voluntary departure and work authorization to the estimated
    1.5 million spouses and children of aliens granted legal status under IRCA—aliens who
    would eventually “acquire lawful permanent resident status” and be able to petition on
    behalf of their family members. Family Fairness Memorandum at 1; see supra p. 57. Later
    that year, Congress granted the beneficiaries of the Family Fairness program an indefinite
    stay of deportation. See Immigration Act of 1990, Pub. L. No. 101-649, § 301, 
    104 Stat. 4978
    , 5030. Although it did not make that grant of relief effective for nearly a year,
    Congress clarified that “the delay in effectiveness of this section shall not be construed as
    reflecting a Congressional belief that the existing family fairness program should be
    76
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    other programs Congress has implicitly endorsed, the program serves
    substantial and particularized humanitarian interests. Removing the par-
    ents of U.S. citizens and LPRs—that is, of children who have established
    permanent legal ties to the United States—would separate them from their
    nuclear families, potentially for many years, until they were able to secure
    visas through the path Congress has provided. During that time, both the
    parents and their U.S. citizen or LPR children would be deprived of both
    the economic support and the intangible benefits that families provide.
    We recognize that the proposed program would likely differ in size
    from these prior deferred action programs. Although DHS has indicated
    that there is no reliable way to know how many eligible aliens would
    actually apply for or would be likely to receive deferred action following
    individualized consideration under the proposed program, it has informed
    us that approximately 4 million individuals could be eligible to apply. See
    Shahoulian E-mail. We have thus considered whether the size of the
    program alone sets it at odds with congressional policy or the Executive’s
    duties under the Take Care Clause. In the absence of express statutory
    guidance, it is difficult to say exactly how the program’s potential size
    bears on its permissibility as an exercise of executive enforcement discre-
    tion. But because the size of DHS’s proposed program corresponds to the
    size of a population to which Congress has granted a prospective entitle-
    ment to lawful status without numerical restriction, it seems to us difficult
    to sustain an argument, based on numbers alone, that DHS’s proposal to
    grant a limited form of administrative relief as a temporary interim meas-
    ure exceeds its enforcement discretion under the INA. Furthermore, while
    the potential size of the program is large, it is nevertheless only a fraction
    of the approximately 11 million undocumented aliens who remain in the
    United States each year because DHS lacks the resources to remove them;
    and, as we have indicated, the program is limited to individuals who
    would be unlikely to be removed under DHS’s proposed prioritization
    policy. There is thus little practical danger that the program, simply by
    virtue of its size, will impede removals that would otherwise occur in its
    absence. And although we are aware of no prior exercises of deferred
    modified in any way before such date.” 
    Id.
     § 301(g). INS’s policies for qualifying Third
    Preference visa applicants and nurses eligible for H-1 nonimmigrant status likewise
    extended to aliens with prospective entitlements to lawful status. See supra p. 56.
    77
    
    38 Op. O.L.C. 39
     (2014)
    action of the size contemplated here, INS’s 1990 Family Fairness policy,
    which Congress later implicitly approved, made a comparable fraction of
    undocumented aliens—approximately four in ten—potentially eligible for
    discretionary extended voluntary departure relief. Compare CRS Immi-
    gration Report at 22 (estimating the Family Fairness policy extended to
    1.5 million undocumented aliens), with Office of Policy and Planning,
    INS, Estimates of the Unauthorized Immigrant Population Residing in the
    United States: 1990 to 2000 at 10 (2003) (estimating an undocumented
    alien population of 3.5 million in 1990); see supra notes 5, 15 (discussing
    extended voluntary departure and Congress’s implicit approval of the
    Family Fairness policy). This suggests that DHS’s proposed deferred
    action program is not, simply by virtue of its relative size, inconsistent
    with what Congress has previously considered a permissible exercise of
    enforcement discretion in the immigration context.
    In light of these considerations, we believe the proposed expansion of
    deferred action to the parents of U.S. citizens and LPRs is lawful. It
    reflects considerations—responding to resource constraints and to particu-
    larized humanitarian concerns arising in the immigration context—that
    fall within DHS’s expertise. It is consistent with congressional policy,
    since it focuses on a group—law-abiding parents of lawfully present
    children who have substantial ties to the community—that Congress itself
    has granted favorable treatment in the immigration process. The program
    provides for the exercise of case-by-case discretion, thereby avoiding
    creating a rule-like entitlement to immigration relief or abdicating DHS’s
    enforcement responsibilities for a particular class of aliens. And, like
    several deferred action programs Congress has approved in the past, the
    proposed program provides interim relief that would prevent particular-
    ized harm that could otherwise befall both the beneficiaries of the pro-
    gram and their families. We accordingly conclude that the proposed
    program would constitute a permissible exercise of DHS’s enforcement
    discretion under the INA.
    2.
    We now turn to the proposed deferred action program for the parents of
    DACA recipients. The relevant considerations are, to a certain extent,
    similar to those discussed above: Like the program for the parents of U.S.
    78
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    citizens and LPRs, the proposed program for parents of DACA recipients
    would respond to severe resource constraints that dramatically limit
    DHS’s ability to remove aliens who are unlawfully present, and would be
    limited to individuals who would be unlikely to be removed under DHS’s
    proposed prioritization policy. And like the proposed program for LPRs
    and U.S. citizens, the proposed program for DACA parents would pre-
    serve a significant measure of case-by-case discretion not to award de-
    ferred action even if the general eligibility criteria are satisfied.
    But the proposed program for parents of DACA recipients is unlike the
    proposed program for parents of U.S. citizens and LPRs in two critical
    respects. First, although DHS justifies the proposed program in large part
    based on considerations of family unity, the parents of DACA recipients
    are differently situated from the parents of U.S. citizens and LPRs under
    the family-related provisions of the immigration law. Many provisions of
    the INA reflect Congress’s general concern with not separating individu-
    als who are legally entitled to live in the United States from their immedi-
    ate family members. See, e.g., 
    8 U.S.C. § 1151
    (b)(2)(A)(i) (permitting
    citizens to petition for parents, spouses, and children); 
    id.
     § 1229b(b)(1)
    (allowing cancellation of removal for relatives of citizens and LPRs). But
    the immigration laws do not express comparable concern for uniting
    persons who lack lawful status (or prospective lawful status) in the United
    States with their families. DACA recipients unquestionably lack lawful
    status in the United States. See DACA Toolkit at 8 (“Deferred action . . .
    does not provide you with a lawful status.”). Although they may presump-
    tively remain in the United States, at least for the duration of the grant of
    deferred action, that grant is both time-limited and contingent, revocable
    at any time in the agency’s discretion. Extending deferred action to the
    parents of DACA recipients would therefore expand family-based immi-
    gration relief in a manner that deviates in important respects from the
    immigration system Congress has enacted and the policies that system
    embodies.
    Second, as it has been described to us, the proposed deferred action
    program for the parents of DACA recipients would represent a significant
    departure from deferred action programs that Congress has implicitly
    approved in the past. Granting deferred action to the parents of DACA
    recipients would not operate as an interim measure for individuals to
    whom Congress has given a prospective entitlement to lawful status. Such
    79
    
    38 Op. O.L.C. 39
     (2014)
    parents have no special prospect of obtaining visas, since Congress has
    not enabled them to self-petition—as it has for VAWA self-petitioners
    and individuals eligible for T or U visas—or enabled their undocumented
    children to petition for visas on their behalf. Nor would granting deferred
    action to parents of DACA recipients, at least in the absence of other
    factors, serve interests that are comparable to those that have prompted
    implementation of deferred action programs in the past. Family unity is,
    as we have discussed, a significant humanitarian concern that underlies
    many provisions of the INA. But a concern with furthering family unity
    alone would not justify the proposed program, because in the absence of
    any family member with lawful status in the United States, it would not
    explain why that concern should be satisfied by permitting family mem-
    bers to remain in the United States. The decision to grant deferred action
    to DACA parents thus seems to depend critically on the earlier decision to
    make deferred action available to their children. But we are aware of no
    precedent for using deferred action in this way, to respond to humanitari-
    an needs rooted in earlier exercises of deferred action. The logic underly-
    ing such an expansion does not have a clear stopping point: It would
    appear to argue in favor of extending relief not only to parents of DACA
    recipients, but also to the close relatives of any alien granted deferred
    action through DACA or any other program, those relatives’ close rela-
    tives, and perhaps the relatives (and relatives’ relatives) of any alien
    granted any form of discretionary relief from removal by the Executive.
    For these reasons, the proposed deferred action program for the parents
    of DACA recipients is meaningfully different from the proposed program
    for the parents of U.S. citizens and LPRs. It does not sound in Congress’s
    concern for maintaining the integrity of families of individuals legally
    entitled to live in the United States. And unlike prior deferred action
    programs in which Congress has acquiesced, it would treat the Execu-
    tive’s prior decision to extend deferred action to one population as justify-
    ing the extension of deferred action to additional populations. DHS, of
    course, remains free to consider whether to grant deferred action to indi-
    vidual parents of DACA recipients on an ad hoc basis. But in the absence
    of clearer indications that the proposed class-based deferred action pro-
    gram for DACA parents would be consistent with the congressional
    policies and priorities embodied in the immigration laws, we conclude
    that it would not be permissible.
    80
    Prioritizing and Deferring Removal of Certain Unlawfully Present Aliens
    III.
    In sum, for the reasons set forth above, we conclude that DHS’s pro-
    posed prioritization policy and its proposed deferred action program for
    parents of U.S. citizens and lawful permanent residents would be legally
    permissible, but that the proposed deferred action program for parents of
    DACA recipients would not be permissible.
