    On Appeal from the United States District Court for the Southern
    District of New York
    ARGUED: JANUARY 6, 2022
    DECIDED: APRIL 6, 2022
    Before: JACOBS, RAGGI, and NARDINI, Circuit Judges.
    Defendants-Appellants United States Citizenship and
    Immigration Services, United States Department of State, and United
    States Immigration and Customs Enforcement appeal from three
    orders of the district court requiring them to produce documents in
    response to requests from Plaintiff-Appellee the Knight First
    Amendment Institute at Columbia University under the Freedom of
    Information Act. The district court (Andrew Carter, J.) ordered
    disclosure of three sets of documents: (1) portions of Volume 9 of the
    Foreign Affairs Manual; (2) the questions that are used to determine
    whether to apply the “Terrorism Related Inadmissibility Ground” to
    applicants for immigration benefits; and (3) a memo titled “ICE
    Ability to Use 212(a)(3)(C) Foreign Policy Charge.” We hold that the
    Department of State and United States Citizenship and Immigration
    Services properly withheld the first two sets of documents under
    FOIA Exemption 7(E). We therefore REVERSE the orders of the
    district court requiring disclosure of those materials. With respect to
    the third, it is unclear whether the agency has already complied fully
    with the district court’s order, in which case its appeal would be moot.
    Accordingly, we REMAND to allow the parties to further develop the
    record.

    WILLIAM J. NARDINI, Circuit Judge:
    The Freedom of Information Act, 
    5 U.S.C. § 552
     (“FOIA”),
    enacted in 1966, allows citizens to find out what their government is
    up to. FOIA embodies a strong policy in favor of disclosing materials
    in response to citizens’ requests. In some circumstances, though,
    Congress has determined that other interests—such as personal
    privacy, national security, or foreign policy—outweigh the need for
    transparency. These circumstances are embodied by a limited set of
    3
    statutory exemptions from FOIA’s disclosure requirements. This case
    requires us to determine the scope of one such exemption.
    Defendants-Appellants     United    States   Citizenship    and
    Immigration Services (“USCIS”), United States Department of State
    (“DOS”), and United States Immigration and Customs Enforcement
    (“ICE”) appeal from three orders of the United States District Court
    for the Southern District of New York (Andrew Carter, J.) entered on
    September 13, 2019, September 23, 2019, and September 13, 2020,
    requiring them to produce certain documents in response to FOIA
    requests from the Knight First Amendment Institute at Columbia
    University (“Knight”). Knight requested documents concerning the
    agencies’ interpretation and implementation of provisions of the
    Immigration and Nationality Act (“INA”) that allow exclusion of
    aliens from the United States based on the aliens’ connections to or
    endorsement of terrorist activity. The parties have resolved several
    of Knight’s requests, leaving only three sets of documents at issue on
    4
    appeal: (1) portions of Volume 9 of the Foreign Affairs Manual; (2) the
    questions that USCIS uses to determine whether to apply the
    “Terrorism Related Inadmissibility Ground” to applicants for
    immigration benefits; and (3) an ICE memo titled “ICE Ability to Use
    212(a)(3)(C) Foreign Policy Charge.” We hold that DOS and USCIS
    properly withheld the first two sets of documents under FOIA
    Exemption 7(E). With respect to the third, the record is unclear as to
    whether ICE has already complied fully with the district court’s
    order, which would render its appeal moot. We therefore remand for
    further proceedings on that issue.
    BACKGROUND
    I.    Knight’s Freedom of Information Act Request
    The INA governs immigration and citizenship in the United
    States. See 8 U.S.C. ch. 12. Section 212 of the INA excludes from
    admission to the U.S. any alien who “endorses or espouses terrorist
    activity or persuades others to endorse or espouse terrorist activity or
    5
    support a terrorist organization[,]” 
    8 U.S.C. § 1182
    (a)(3)(B)(i)(VII), or
    who is “a representative . . . of . . . a political, social, or other group
    that    endorses        or      espouses        terrorist      activity[,]”   
    id.
    § 1182(a)(3)(B)(i)(IV)(bb)       (together,      the        “endorse-or-espouse
    provisions”). The INA also excludes aliens whose admission the
    Secretary of State “has reasonable ground to believe would have
    potentially serious adverse foreign policy consequences for the
    United States.” Id. § 1182(a)(3)(C)(i) (the “foreign-policy provision”).
    An alien is not excludable “because of the alien’s past, current, or
    expected beliefs, statements, or associations . . . [that] would be lawful
    within the United States, unless the Secretary of State personally
    determines that the alien’s admission would compromise a
    compelling     United        States   foreign      policy      interest.”     Id.
    § 1182(a)(3)(C)(iii).
    On August 7, 2017, Knight filed FOIA requests with several
    executive agencies, including DOS, USCIS, and ICE. Knight asserted
    6
    that its FOIA requests were prompted by President Donald Trump’s
    statements and executive orders related to the above-described INA
    provisions.      Specifically, President Trump purportedly stated his
    intention to institute an “‘ideological screening test’ for admission
    into the United States and said that a ‘new screening test’ involving
    ‘extreme, extreme vetting’ was overdue.” Joint App’x at 37 (quoting
    Karen Deyoung, Trump Proposes Ideological Test for Muslim Immigrants
    and   Visitors     to   the   U.S.,   Wash.   Post    (Aug.    15,   2016),
    https://perma.cc/G9SCEPHT). President Trump subsequently issued
    two executive orders that are at issue here: Exec. Order No. 13769, 
    82 Fed. Reg. 8977
     (Jan. 27, 2017) and Exec. Order No. 13780, 
    82 Fed. Reg. 13209
    , 13215 (Mar. 6, 2017) (together, the “Executive Orders”).
    The Executive Orders directed executive                 departments,
    including DOS and the Department of Homeland Security (under
    which USCIS and ICE fall), to develop a more robust vetting program
    for immigrants entering the country.                 They required “the
    7
    development of a uniform baseline for screening and vetting
    standards and procedures” and processes to “ensur[e] the proper
    collection of all information necessary for a rigorous evaluation of all
    grounds of inadmissibility.” Exec. Order No. 13780, 82 Fed. Reg. at
    13215. 1
    Knight sought several categories of records related to the way
    that agencies interpreted and implemented the endorses-or-espouses
    provisions and the foreign-policy provision of the INA under the
    Executive Orders. The agencies released a substantial volume of
    material in response to Knight’s request but withheld some
    documents in whole or in part under various FOIA exemptions. For
    example, USCIS produced 957 pages in their entirety but withheld 357
    pages. The parties resolved most disputes about the scope of the
    1President Joseph Biden revoked the Executive Orders on the first day of his
    administration. See Proclamation No. 10,141, 
    86 Fed. Reg. 7005
     (Jan. 20, 2021).
    Knight asserts that it maintains an interest in the material it requested because of
    “the expanded focus on social media accounts in immigration vetting in recent
    years, and the Biden Administration’s active review and reconsideration of these
    policies.” Knight Br. at 8.
    8
    agencies’ withholding between themselves, and Knight filed suit
    seeking an order requiring the agencies to produce a subset of the
    documents about which the parties were unable to agree. Before the
    district court, the parties filed cross-motions for partial summary
    judgment. Three sets of records addressed in the district court’s
    rulings on those motions remain at issue in this appeal: (1) portions
    of Volume 9 of the Foreign Affairs Manual (“9 FAM”); (2) a set of
    training slides, manuals, and guides containing questions relating to
    the   Terrorism   Related   Inadmissibility   Grounds    (the   “TRIG
    questions”); and (3) an ICE memorandum titled “ICE Ability to Use
    212(a)(3)(C) Foreign Policy Charge” (the “ICE memo”).
    The court addressed the 9 FAM records in its September 13,
    2019, ruling on the parties’ first cross-motions for summary judgment.
    It addressed the TRIG questions and the ICE memo in its September
    23, 2019, ruling on the parties’ second cross-motions for summary
    judgment. And it addressed the parties’ additional arguments related
    9
    to the 9 FAM records and TRIG questions in its September 13, 2020,
    ruling        on    the   government’s        motion   for   clarification   and
    reconsideration.
    A.        Three Sections of the Foreign Affairs Manual
    Knight requested “[a]ll Foreign Affairs Manual sections
    (current and former) relating to the endorse or espouse provisions or
    the foreign policy provision, as well as records discussing,
    interpreting, or providing guidance regarding such sections.” Joint
    App’x at 39.
    DOS describes the Foreign Affairs Manual and the associated
    Handbooks as
    a single, comprehensive, and authoritative source for the
    Department’s organization structures, policies, and
    procedures that govern the operations of the State
    Department, the Foreign Service and, when applicable,
    other federal agencies. The FAM (generally policy) and
    the [Foreign Affairs Handbooks] (generally procedures)
    together convey codified information to Department
    staff and contractors so they can carry out their
    responsibilities in accordance with statutory, executive
    and Department mandates.
    10
    DOS, Foreign Affairs Manual and Handbook, https://fam.state.gov
    [https://perma.cc/5JJC-TKC6] (last visited Mar. 22, 2022).
    DOS provided relevant portions of the manual to Knight but
    redacted certain sections of 9 FAM. In general, 9 FAM includes
    “directives and guidance” for DOS personnel adjudicating U.S. visas.
    9 FAM 101.1. DOS asserted that the redacted portions of the manual
    were exempt from disclosure under Exemption 7(E). 2 Versions of
    three partially redacted sections remain at issue: 9 FAM 302.6, 9 FAM
    40.32, and 9 FAM 302.14.
    • Eight versions of 9 FAM 302.6. DOS redacted eight versions of
    9 FAM 302.6, titled “Ineligibilities Based on Terrorism Related
    Grounds.” Joint App’x at 66. It asserted that the redacted
    2 Exemption 7(E) excludes from the disclosure requirement “records or
    information compiled for law enforcement purposes [the release of which] . . .
    would disclose techniques and procedures for law enforcement investigations or
    prosecutions, or would disclose guidelines for law enforcement investigations or
    prosecutions if such disclosure could reasonably be expected to risk circumvention
    of the law.” 
    5 U.S.C. § 552
    (b)(7)(E).
    11
    portions “disclose law enforcement investigation techniques,
    procedures, and guidelines.” 
    Id.
     Its Vaughn index 3 lists each
    redaction and explains how the redaction falls within the
    exemption.       For example, “9 FAM 302.6-2(B)(1)(b). reveals
    interagency cooperation procedures during the process of
    checking for terrorism-related ineligibilities,” id.; and “9 FAM
    302.6-2(B)(4)e. (2) and (5) gives guidelines for when spouses
    and children trigger the requirement for further security
    investigation and how to conduct that process,” 
    id. at 67
    . DOS
    concluded that “[d]isclosure of any of the above information
    could reasonably be expected to risk circumvention of the law
    3As we have explained:
    The Vaughn index procedure was developed to avoid the cumbersome
    alternative of routinely having a district court examine numerous multi-
    page documents in camera to make exemption rulings. See Vaughn v. Rosen,
    
    484 F.2d 820
    , 825 (D.C. Cir. 1973). . . . A Vaughn index typically lists the
    titles and descriptions of the responsive documents that the Government
    contends are exempt from disclosure. In some cases detailed affidavits
    from agency officials may suffice to indicate that requested documents are
    exempt from disclosure.
    N.Y. Times Co. v. U.S. Dep't of Just., 
    758 F.3d 436
    , 438–39 (2d Cir.), supplemented by

     (2d Cir. 2014) (footnotes omitted).

    because terrorists and other bad actors could use it to conceal
    derogatory information, provide fraudulent information, or
    otherwise circumvent the security checks put in place to ensure
    that terrorists and other bad actors cannot gain visas into the
    United States.” 
    Id. at 68
    .
    • Three versions of 9 FAM 40.32. DOS redacted three versions
    of 9 FAM 40.32, which it reports are “earlier iterations of
    sections that are now incorporated into 9 FAM 302.6.” 
    Id.
     As
    with 9 FAM 302.6, DOS provided an explanation for each
    redaction. It provided the same conclusion for withholding as
    with 9 FAM 302.6 (that is, disclosure could allow terrorists or
    other bad actors to circumvent the law).
    • One version of 9 FAM 302.14. DOS made several redactions to
    one version of 9 FAM 302.14, titled “Ineligibility Based on
    Sanctioned Activities.” 
    Id. at 69
    . It asserted that the redacted
    portions “disclose law enforcement investigation techniques,
    13
    procedures, and guidelines” about several topics.     
    Id.
       For
    example, it stated that the redacted portions included
    “guidelines for conducting the security investigation process,
    including whether certain procedures are mandatory, and
    what information to include in a request for those procedures.”
    
    Id.
    The district court held that 9 FAM was not “‘compiled for law
    enforcement purposes’ even if some sections of the FAM may serve
    those purposes.” Knight First Amend. Inst. at Columbia Univ. v. U.S.
    Dep’t of Homeland Sec., 
    407 F. Supp. 3d 311
    , 332 (S.D.N.Y. 2019)
    (“Knight I”). Because DOS is a “mixed-function agency” performing
    both administrative and law enforcement functions, the court
    explained it would “‘scrutinize with some skepticism the particular
    purpose claimed for disputed documents redacted under FOIA
    14
    Exemption 7.’” 
    Id.
     (quoting Tax Analysts v. IRS, 
    294 F.3d 71
    , 77 (D.C.
    Cir. 2002)). 4
    First, the district court noted that some of the redacted portions
    fell within the “Definitions” section of 9 FAM and that that section
    appeared to derive from definitions included in the INA. 
    Id.
     at 332–
    33. The district court thus held that “[t]he similarity between the
    withheld information and the INA’s text . . . suggests Exemption 7(E)
    does not apply.” Id. at 333.
    Second, DOS admitted that the FAM “generally consists of
    policy.” The district court agreed, observing that “mere descriptions
    of codified law and policy, even those including interpretation and
    application of immigration laws and regulations, are not protected
    under Exemption 7(E).” Id. at 333 (internal quotation marks and
    citations omitted). Rather, “[t]o be ‘compiled for law enforcement
    4 We have frequently noted the District of Columbia Circuit’s “particular FOIA
    expertise” and looked to its decisions for guidance in interpreting the FOIA. See,
    e.g., Whitaker v. Dep’t of Commerce, 
    970 F.3d 200
    , 206 & n.25 (2d Cir. 2020).
    15
    purposes,’ the information must go a step further and describe
    ‘proactive steps’ for preventing criminal activity and maintaining
    security.” 
    Id.
     (quoting Milner v. Dep’t of the Navy, 
    562 U.S. 562
    , 582
    (2011) (Alito, J., concurring)).
    Finally, the court noted that some records appeared to contain
    “interpretive information” which DOS characterized as “guidelines,”
    and held that this type of interpretive document falls outside of
    Exemption 7(E). 
    Id.
     For example, DOS’s description of 9 FAM 302.6-
    3(B) explained that it included “guidelines for situations in which an
    individual may cease to be inadmissible.” 
    Id.
     (internal quotation
    marks omitted). The court held that it was not clear “how explaining
    to the public what may constitute grounds for inadmissibility—
    essentially a legal interpretation—may potentially help an individual
    circumvent the law.” 
    Id.
    16
    Based on the above conclusions, the district court ordered
    disclosure of the unredacted versions of the three 9 FAM sections at
    issue. 
    Id.
    B.     Terrorism-Related Inadmissibility Ground Questions
    Next, Knight requested “[a]ll records containing policies,
    procedures, or guidance regarding the application or waiver of the
    endorse or espouse provisions or the foreign policy provision.” Joint
    App’x at 39. In response, USCIS disclosed several presentation slides,
    training manuals, and other guides. In some documents, USCIS
    redacted “model or sample questions for immigration officers to use
    when screening applicants.” Id. at 552. The questions are intended to
    help determine, for example, “whether an applicant provides
    material support for terrorism, and to determine whether an
    applicant provides support to a terrorist organization under duress.”
    Id. The agency explained that the process for asking the questions is
    dynamic. The withheld material includes not only “TRIG specific
    17
    model questions that USCIS immigrations officers should ask when
    interviewing applicants,” but also “follow-up questions that
    immigration officers should ask when they spot issues in testimony
    that could trigger a TRIG bar.” Joint App’x at 181–82.
    USCIS asserted that the TRIG questions “reflect specialized
    methods that USCIS has refined through its decades of enforcing
    United States immigration laws.” Id. The agency asserted that the
    TRIG questions were therefore exempt from disclosure under
    Exemption 7(E).
    The district court concluded that the TRIG questions were not
    “special or technical.” Knight First Amend. Inst. at Columbia Univ. v.
    U.S. Dep’t of Homeland Sec., 
    407 F. Supp. 3d 334
    , 353 (S.D.N.Y. 2019)
    (“Knight II”). It also explained that those questioned using the TRIG
    questions would necessarily learn the questions, and “USCIS
    submit[ted] no evidence suggesting its methods are so special that
    interviewees cannot parrot them to whomever they choose.” 
    Id.
     at
    18
    354. The court therefore concluded that Exemption 7(E) did not
    apply. 
    Id.
    C.     Memorandum Titled “ICE Ability to Use 212(a)(3)(C)
    Foreign Policy Charge”
    Knight made several requests for legal or policy memoranda
    related to the foreign policy provision. ICE identified as responsive a
    memorandum titled “ICE Ability to Use 212(a)(3)(C) Foreign Policy
    Charge.” It redacted the memorandum in full except for the title.
    ICE stated that the memorandum “contains information
    protected by the attorney-client privilege.           The materials reflect
    opinions, analysis, guidance and legal advice provided by attorneys
    in the ICE Office of the Principal Legal Advisor (OPLA), regarding a
    particular section of the INA.” 5 Joint App’x at 249. In a separate
    declaration submitted in support of summary judgment, ICE
    supplemented its description, further stating that the memo “includes
    5ICE initially claimed attorney-client privilege over the memo but withdrew that
    assertion during summary judgment proceedings. Appellants’ Br. at 13 n.4.
    19
    a brief summary with notes and quotes for determining whether
    Section 212(a)(3)(C) can be used by the Secretary of State as grounds
    for inadmissibility.”      Joint App’x at 563.       It asserted that “th[e]
    document did not bind the agency[,]” was “not organized like typical
    ICE memoranda[,] and [was] not signed by or formally addressed to
    ICE leadership.      The memorandum simply supplie[d] factors for
    consideration while providing analysis on whether the Secretary of
    State should use Section 212(a)(3)(C) Foreign Policy Charge to render
    an alien inadmissible under the INA.” 
    Id.
     Thus, ICE withheld the
    memo under Exemption 5 and the deliberative process privilege. 6
    The district court found that ICE had failed to establish that the
    ICE memo was subject to the deliberative process privilege through
    Exemption 5. Specifically, the court found the document was not
    “pre-decisional” because ICE did not show that the memo “‘formed
    6Exemption 5 provides that disclosure is not required for “inter-agency or intra-
    agency memorandums or letters that would not be available by law to a party
    other than an agency in litigation with the agency.” 
    5 U.S.C. § 552
    (b)(5).

    an essential link in a specific consultative process, reflects the
    personal opinions of the writer rather than the policy of the agency,
    [or] if released would inaccurately reflect or prematurely disclose the
    views of the agency.’” Knight II, 407 F. Supp. 3d at 345 (quoting
    Brennan Ctr. for Just. at N.Y. Univ. Sch. of Law v. U.S. Dep’t of Just., 
    697 F.3d 184
    , 202 (2d Cir. 2012) (emphasis added by district court)). The
    memo appeared “more akin to opinions regarding how to interpret
    policy rather than recommendations as to how to make policy.” 
    Id.
     It
    was therefore “post-decisional explanation” rather than “pre-
    decisional advice” and fell outside of Exemption 5. 
    Id.
     (internal
    quotation marks omitted). The district court therefore directed ICE to
    “disclose reasonably segregable portions of [the ICE memo] that
    reflect current immigration policy.” 
    Id.
     at 345–46.
    D.     Motion for Reconsideration
    After the district court decided Knight I and Knight II, DOS and
    USCIS moved for reconsideration and clarification of the court’s
    21
    decisions with respect to 9 FAM and the TRIG questions, respectively.
    Knight First Amendement Inst. at Columbia Univ. v. U.S. Dep’t of
    Homeland Sec., No. 1:17-CV-7572, 
    2020 WL 5512540
    , at *6 (S.D.N.Y.
    Sept. 13, 2020) (“Knight III”). The agencies requested clarification as
    to whether the district court intended to order immediate disclosure
    of the records, or to provide the agencies an opportunity to further
    justify the application of Exemption 7(E). 
    Id. at *6
    . In the event that
    the court intended to require immediate disclosure, the agencies
    asked the court to reconsider and instead review the documents in
    camera. 
    Id.
    The court clarified that it intended to order immediate
    disclosure of the Exemption 7(E) documents and declined the
    invitation to conduct in camera review. 
    Id.
     at *7–*8. It explained that
    “DOS and USCIS submitted sufficiently detailed justifications for
    withholding the FAM sections and TRIG questions respectively,” but
    22
    that it “understood the agencies’ arguments and was not persuaded.”
    
    Id. at *8
    .
    DISCUSSION
    We review the grant of summary judgment de novo. See Long v.
    Off. of Pers. Mgmt.,

    I.    Documents Withheld under FOIA Exemption 7(E)
    DOS withheld the 9 FAM records, and USCIS the TRIG
    questions, under FOIA Exemption 7(E). That exemption excludes
    documents from FOIA’s disclosure requirement if an agency satisfies
    two conditions. First, the agency must show that the records were
    “compiled for law enforcement purposes.”           
    5 U.S.C. § 552
    (b)(7).
    Second, the agency must show that the records either (1) “would
    disclose techniques and procedures for law enforcement investigations
    or prosecutions”; or (2) “would disclose guidelines for law
    enforcement investigations or prosecutions” and “such disclosure
    could reasonably be expected to risk circumvention of the law.” 
    Id.
     at
    24
    § 552(b)(7)(E) (emphasis added). Thus, to withhold “guidelines for
    law enforcement,” an agency must make an additional showing that
    is not required before withholding “techniques or procedures.”
    A.     DOS established that the 9 FAM materials are exempt
    from disclosure under Exemption 7(E)
    Knight argues that DOS has failed to establish that the 9 FAM
    materials were “compiled for law enforcement purposes” or that they
    include “techniques or procedures” or “guidelines” for law
    enforcement whose disclosure would risk circumvention of the law.
    We disagree.
    1. The 9 FAM material was compiled for law
    enforcement purposes
    “The threshold requirement for qualifying under Exemption 7
    turns on the purpose for which the document sought to be withheld
    was prepared.” F.B.I. v. Abramson, 
    456 U.S. 615
    , 624 (1982). The
    Supreme Court has interpreted this requirement broadly.          For
    example, a document initially compiled for law enforcement
    purposes but later provided to a different, non-law-enforcement
    25
    agency may still fall within Exemption 7. 
    Id.
     at 624–25. Still, an
    agency that performs both administrative and law-enforcement
    functions is “subject to an exacting standard when it comes to the
    threshold requirement of Exemption 7.” Tax Analysts v. I.R.S., 
    294 F.3d 71
    , 77 (D.C. Cir. 2002). DOS acknowledges that it is a “mixed-
    function” agency.
    Knight argues that 9 FAM was not compiled for law
    enforcement purposes because it was compiled “to help an agency
    apply the law—in this case to process visa applications,” which is “not
    a sufficient basis to conclude that the information was compiled to
    enforce the law.” Knight Br. at 29 (citing United Am. Fin., Inc. v. Potter,
    
    531 F. Supp. 2d 29
    , 46 (D.D.C. 2008)).         But as Justice Alito has
    explained, “[t]he ordinary understanding of law enforcement
    includes not just the investigation and prosecution of offenses that
    have already been committed, but also proactive steps designed to
    prevent criminal activity and to maintain security.” Milner v. Dep't of
    26
    Navy, 
    562 U.S. 562
    , 582 (2011) (Alito, J., concurring). Enforcing the law
    always requires a degree of analysis and application. While some
    aspects of visa adjudication might fall outside the common
    understanding of “law enforcement,” the provisions at issue here do
    not. DOS’s explanations for its redactions clearly establish that the
    redacted provisions relate to the detection of connections to terrorism.
    See, e.g., Joint App’x at 67 (summarizing reason for redactions,
    including “defin[ing] terrorist activity, adding specific details and
    clarification about how they fit into the security investigation
    process.”). The detection and prevention of terrorism are archetypal
    law-enforcement purposes.
    The district court concluded that the 9 FAM documents were
    not compiled for law enforcement purposes because they included
    “mere descriptions of codified law and policy” and “to be compiled
    for law enforcement purposes, the information must go a step further
    and describe proactive steps for preventing criminal activity and
    27
    maintaining security.” Knight I, 407 F. Supp. 3d at 333 (internal
    quotation marks omitted). That view finds no support in the text of
    the exemption. The threshold inquiry under Exemption 7 is the
    reason for which material was compiled, and the material should be
    considered as a whole rather than broken into parts and scrutinized
    in isolation. While an agency’s discrete description of law and policy
    might not be subject to exemption in every context, when a larger
    series of descriptions is compiled to provide comprehensive guidance
    to employees in the field on how to apply and enforce the laws within
    the agency’s purview, that subsequent compilation enters the
    potential ambit of Exemption 7(E). An agency’s compilation of laws
    and policies might provide insight into its conduct and approaches to
    law enforcement even if it reveals no “proactive steps.”         Such
    compilation might reveal the agency’s reliance on specific laws,
    reflecting the use of certain techniques or the limitations on the
    implementation of those techniques in the field. Certainly, records
    28
    that reflect only descriptions of publicly available statutes are less
    likely to create a risk of “circumvention of the law” if released. 
    5 U.S.C. § 552
    (b)(7)(E). But that does not mean they were not “compiled
    for law enforcement purposes” in the first instance—only that they
    might not meet the requirements of Exemption 7(E) at the second
    step.    Here, DOS has established that 9 FAM includes specific
    guidance to DOS employees on how to detect ties to terrorism. We
    conclude, therefore, that it was “compiled for law enforcement
    purposes” within the meaning of Exemption 7(E).
    2. The 9 FAM materials would disclose techniques,
    procedures, or guidelines for enforcement
    Knight next argues that, even if the records were “compiled for
    law enforcement purposes,” some of DOS’s redactions fall outside
    Exemption 7(E) because they do not cover material reflecting
    techniques or procedures for law enforcement investigations or
    prosecutions. Knight contends that the non-redacted portions of 9
    FAM include only high-level summaries rather than techniques or
    29
    procedures. Some of the material “appears to consist of definitions
    and explanations of statutory language.” Knight Br. at 34. And
    “some of the withheld materials appear to summarize publicly
    available statutes, memoranda, and directives.” Knight Br. at 36.
    With each assertion, though, Knight asks us to draw inferences about
    the redacted material from context that are contradicted by DOS’s
    affidavits and Vaughn index. On summary judgment, we accept an
    agency’s affidavits as true unless they are “controverted by either
    contrary evidence in the record or by evidence of agency bad faith.”
    Am. C.L. Union, 901 F.3d at 133 (internal quotation marks and
    alteration omitted).    Accordingly, we cannot credit Knight’s
    contentions about what the 9 FAM redactions “appear” to include in
    the face of an agency affidavit attesting to what they actually do
    include, particularly in the absence of evidence of bad faith. In any
    event, we are not persuaded that Knight’s proposed inferences from
    context are reasonable. For example, Knight asserts it is “unlikely”
    30
    that redactions include more information than in publicly available
    sources because the redactions are relatively short. Knight Br. at 37.
    But DOS’s Vaughn index explicitly states that some redactions include
    material that has not been publicly disclosed. See, e.g., Joint App’x at
    67 (explaining that one redaction “lists credible sources of evidence
    that may be used in recommending a finding, including sources that are
    not public knowledge”) (emphasis added).
    Knight next argues that DOS’s Vaughn index describes the
    redacted material as guidelines, while they now state in their brief
    that it reflects techniques or procedures. “Techniques and procedures
    . . . refers to how law enforcement officials go about investigating a
    crime.” Allard K. Lowenstein Int'l Hum. Rts. Project v. Dep't of Homeland
    Sec., 
    626 F.3d 678
    , 682 (2d Cir. 2010) (“Lowenstein Project”) (internal
    quotation marks omitted). In contrast, “guidelines . . . generally refers
    in the context of Exemption 7(E) to resource allocation.” 
    Id.
     (internal
    quotation marks omitted).        While law-enforcement documents
    31
    revealing techniques and procedures are exempt from disclosure per
    se, documents revealing guidelines are exempt only “if such
    disclosure could reasonably be expected to risk circumvention of the
    law.” 
    Id. at 681
    .
    DOS’s use of the word “guideline” in its Vaughn index is not
    talismanic. Rather, we must consider the substance of the agency’s
    descriptions to determine whether the redacted material contains
    “techniques or procedures” or “guidelines” under FOIA. The phrase
    “techniques or procedures” is not defined in the statute, and we have
    not ascribed to it a hypertechnical meaning. Lowenstein Project, 
    626 F.3d at 682
    . Stated simply, “techniques or procedures” includes both
    law enforcement methods—the actions that law enforcement
    personnel take to identify and neutralize bad actors—as well as the
    triggers for the application of methods. See, e.g., 
    id.
     (describing as a
    “technique or procedure” an agency’s instruction to agents to focus
    on cash-based businesses for audit and investigation).
    32
    Here, we need not decide whether the 9 FAM material is
    properly categorized as “techniques or procedures” rather than
    “guidelines” for law enforcement. Even assuming the more rigorous
    “guideline” standard applies, DOS has established that disclosure of
    the 9 FAM material could reasonably risk circumvention of the law.
    As DOS describes, the redactions to 9 FAM are targeted to those
    specific provisions that delineate how DOS officials should identify
    aliens who may have connections to terrorism, including some
    specific triggers for additional scrutiny. Releasing this information
    would allow an individual with actual terrorist ties to better tailor his
    or her application to avoid detection.       It does not matter, then,
    whether the redactions reflect “techniques or procedures” or
    “guidelines.” Exemption 7(E) would apply in either case.
    Finally, Knight urges that the Vaughn index is too “vague and
    conclusory” to support DOS’s withholding. Knight Br. at 40. To
    justify withholding, an agency must provide “a relatively detailed
    33
    analysis of the withheld material in manageable segments without
    resort to conclusory and generalized allegations of exemptions.”
    Halpern, 
    181 F.3d at 290
     (internal quotation marks and alteration
    omitted). The agency must also “provide an indexing system that
    would subdivide the withheld document under consideration into
    manageable parts cross-referenced to the relevant portion of the
    Government’s justification.”     
    Id.
     (internal quotation marks and
    alteration omitted). In Halpern, for example, we held that an agency’s
    affidavit was sufficient where it provided a high-level explanation of
    categories of information falling within the exemption, and then
    cross-referenced each of those categories against redactions in the
    requested documents. 
    Id.
     at 296–98. Here, too, we conclude that DOS
    satisfied its obligation to provide a detailed overview of the withheld
    material. DOS’s redactions are highly targeted and discrete. See, e.g.,
    Joint App’x at 128 (redacting two sentences on a page). In this context,
    it would not be reasonable to expect DOS to provide more specific
    34
    descriptions; doing so would effectively require disclosure of the
    isolated material it chose to redact. And the agency here went further
    than    Halpern     would      require,     providing     separate,     detailed
    explanations for each redaction.
    In sum, we hold that DOS met its burden to establish that the
    9 FAM materials were compiled for law enforcement purposes; that
    they reflect techniques, procedures, or guidelines of law enforcement;
    and that disclosure would reasonably risk circumvention of the law.
    Accordingly, we reverse the September 13, 2019, ruling of the district
    court insofar as it required DOS to disclose unredacted versions of the
    9 FAM materials.
    B.     USCIS established that the TRIG questions are exempt
    from disclosure under Exemption 7(E)
    We turn next to the TRIG questions. 7               The district court
    concluded that the TRIG questions are not subject to Exemption 7(E),
    7The district court did not address whether the TRIG questions were compiled for
    law enforcement purposes. Knight II, 407 F. Supp. 3d at 353. Knight does not argue
    35
    but USCIS argues this was error. It asserts that the TRIG questions
    constitute techniques or procedures of law enforcement, and that
    releasing them would enable applicants with ties to terrorism to better
    tailor their answers to avoid detection. Knight responds that the
    TRIG questions are not sufficiently specialized to constitute
    techniques and procedures of law enforcement, that they are
    effectively public given that they have been asked of many aliens
    already, and that USCIS has not established that disclosure of the
    TRIG questions would risk circumvention of the law. We hold that
    the TRIG questions constitute “techniques or procedures” of law
    enforcement, and in any event, their disclosure would reasonably risk
    circumvention of the law.        Our conclusion is not altered by the
    possibility that some individual aliens may have been asked some or
    all of the questions.
    on appeal that they were not. Accordingly, we have no occasion to question
    whether USCIS has met its burden at the first step of analysis under Exemption
    7(E).
    36
    The district court found that the TRIG questions were not
    “techniques     or   procedures”        because   “USCIS     [had]    not
    demonstrate[d] its methods are necessarily special or technical.”
    Knight II, 407 F. Supp. 3d at 353. Knight further contends that the
    government must demonstrate that the material it withholds includes
    “‘specialized, calculated technique[s] or procedure[s].’” Knight Br. at 39
    (quoting Am. C.L. Union Found. v. Dep’t of Homeland Sec., 
    243 F. Supp. 3d 393
    , 404 (S.D.N.Y. 2017) (“ACLU v. DHS”) (emphasis added). But
    as noted earlier, the phrase “techniques or procedures” refers simply
    to “how law enforcement officials go about investigating a crime.”
    Lowenstein Project, 
    626 F.3d at 682
     (defining “technique” as “a
    technical method of accomplishing a desired aim”; and “procedure”
    as “a particular way of doing or of going about the accomplishment
    of something” (internal quotation marks omitted)). Our analysis is
    not advanced by adding qualifiers that do not appear in the statute—
    such as “special,” “specialized,” “technical,” or “calculated”—to
    37
    modify the terms “techniques or procedures.” It is not the province
    of the courts to add words to statutes that Congress has enacted. To
    the extent that the district court’s decision could be understood to
    suggest that Exemption 7(E) covers only a subset of “techniques or
    procedures,” we therefore reject such a reading of the statute. And in
    any event, we do not think that any of those four adjectives materially
    aids our analysis of what falls within the scope of “techniques or
    procedures.” 8     The key issue in determining whether redacted
    material contains “techniques or procedures” under Exemption 7(E)
    is whether disclosure of that material would reveal particulars about
    the way in which an agency enforces the law and the circumstances
    that will prompt it to act. In Lowenstein Project, we explained, “if [an]
    agency informs tax investigators that cash-based business are more
    8Indeed, we have used the word “technical” parenthetically in describing the
    definition of “technique.” Lowenstein Project, 
    626 F.3d at 682
    , and so it would be
    redundant to speak of a “technical technique.” Moreover, “technical” in this
    context simply means “of or relating to a particular subject.” Webster’s Third New
    International Dictionary (1986).
    38
    likely to commit tax evasion than other businesses, and therefore
    should be audited with particular care, focusing on such targets
    constitutes a ‘technique or procedure’ for investigating tax evasion.”
    
    626 F.3d at 682
    . The questions that USCIS instructs its employees to
    ask visa applicants to detect ties to terrorism are more closely linked
    to the specific methods employed by government actors than an
    agency’s generic directive to investigate cash-based businesses. We
    hold that the list of TRIG questions employed to effectuate law
    enforcement purposes—to identify potential terrorists and keep them
    from entering the United States—falls squarely within the scope of
    the statutory phrase “techniques or procedures.”
    Even if the TRIG questions were “guidelines” rather than
    “techniques or procedures” of law enforcement, Exemption 7(E)
    would apply because USCIS has established that disclosing the TRIG
    questions would reasonably risk circumvention of the law.           As
    explained earlier, disclosing in advance the specific questions that
    39
    agents may use to suss out and evaluate connections to terrorism
    would help those with terrorist ties to tailor their answers to avoid
    detection. See, e.g., Heartland Alliance Nat’l Immigrant Justice Ctr. v.
    Dep’t of Homeland Sec., 
    840 F.3d 419
    , 421 (7th Cir. 2016) (upholding the
    application of Exemption 7(E) to a list of lower-level terrorist
    organizations, the disclosure of which would allow applicants for
    immigration benefits to conceal ties to those organizations); Ibrahim v.
    Dep’t of State, 
    311 F. Supp. 3d 134
    , 143 (D.D.C. 2018) (upholding the
    application of Exemption 7(E) to “USCIS’s Refugee Application
    Assessment” because “[t]he lines of questions recorded in the
    Assessment highlight circumstances that would have raised national
    security and public safety concerns,” and its disclosure “could
    reasonably be expected to risk circumvention of the law by enabling
    applicants for refugee status to plan strategic but inaccurate
    answers”).
    40
    Finally, Knight asserts, as the district court held, that even if the
    questions could be considered “techniques or procedures” for
    purposes of Exemption 7(E), they are no longer exempt because they
    have been publicly disclosed. See Inner City Press/Cmty. on the Move v.
    Bd. of Governors of the Fed. Rsrv. Sys., 
    463 F.3d 239
    , 249 (2d Cir. 2006).
    The burden of establishing prior public disclosure is on the requester.
    
    Id.
     Knight asserts that it has carried its “burden of production” by
    pointing out that the TRIG questions “become known to applicants
    when the questions are asked in interviews or mailed to them in
    Requests for Evidence.” Knight Br. at 45. 9 But as we have explained,
    “[t]he Supreme Court has limited the public domain exception to
    9Knight invokes the district court’s reasoning in ACLU v. DHS, asserting that
    when an agency has a “practice of asking the questions at issue,” it incurs an
    additional burden to “justify its assertion that . . . [the questions are] not already
    known to the public.” Knight Br. at 46 (quoting ACLU v. DHS, 243 F. Supp. 3d at
    402). We reject any such rule. A FOIA requester bears the burden of production
    on the question of whether material is “publicly available.” Inner City Press, 
    463 F.3d at 245
    . As we explain above, the mere fact that an agency asks certain
    questions to certain individuals does not satisfy the requester’s burden of
    production, because it does not satisfy the threshold showing that such questions
    are available to the general public.
    41
    information that is ‘freely available.’” Inner City Press, 
    463 F.3d at 244
    (quoting U.S. Dep't of Just. v. Reps. Comm. for Freedom of Press, 
    489 U.S. 749
    , 764 (1989)). Thus, to meet this prior-disclosure burden, “the
    requesting party ‘must . . . point[ ] to specific information in the public
    domain that appears to duplicate that being withheld.’” Id. at 249
    (quoting Afshar v. U.S. Dep’t of State, 
    702 F.2d 1125
    , 1130 (D.C. Cir.
    1983) (alterations in original)). In the FOIA context, information is in
    the public domain if it is generally available to the public at large, not
    simply if it happens to be known by select members of the public. See
    U.S. Dep't of Just. v. Reps. Comm. for Freedom of Press, 
    489 U.S. 749
    , 764
    (1989) (distinguishing between information “restricted to . . . a
    particular person or group of class of persons” and information
    “freely available to the public”). The latter is the case here. Perhaps
    an enterprising researcher could identify a pool of visa applicants,
    collect information about what they were asked, and then compile a
    list of common questions they faced. Though doubtful, let us further
    42
    assume that our imaginary researcher would also be able to intuit
    which questions had been posed to ferret out possible terrorists and
    therefore must be on the TRIG list.          Even if all of this might
    conceivably be achieved, the necessity of the reconstruction exercise
    itself demonstrates that the information in question is not in the
    public domain. See, e.g., Davis v. U.S. Dep’t of Just., 
    968 F.2d 1276
    , 1280
    (D.C. Cir. 1992) (holding FOIA requester failed to show public
    disclosure by pointing to newspaper accounts establishing that
    government played tape recordings at trial; rather, requester had
    “burden of showing that there is a permanent public record of the
    exact portions” sought to be disclosed); Bishop v. U.S. Dep’t of
    Homeland Sec., 
    45 F. Supp. 3d 380
    , 391 (S.D.N.Y. 2014) (“[C]ourts have
    acknowledged that Exemption 7(E) applies even when the identity of
    the techniques has been disclosed, but the manner and circumstances
    of the techniques are not generally known, or the disclosure of
    additional details could reduce their effectiveness.” (internal
    43
    quotation marks omitted)); Barouch v. United States Dep’t of Just., 
    87 F. Supp. 3d 10
    , 30 n.13 (D.D.C. 2015) (upholding the application of
    Exemption 7(E) to material showing the “questioning techniques
    used by ATF agents and local law enforcement agents” because
    “disclosure would hinder future use of these tactics” (internal
    quotation marks omitted)). Put another way, the possibility that a
    savvy law-evader might be able to infer the substance of some
    withheld documents by carefully observing an agency’s actions does
    not remove those documents from the ambit of Exemption 7(E). 10
    For these reasons, we conclude that USCIS properly withheld
    the TRIG Questions under Exemption 7(E).                     Those questions
    constitute techniques or procedures of law enforcement.                       We
    therefore reverse the September 23, 2019, ruling of the district court
    10That is particularly so where, as here, the withheld material does not include a
    single script that a motivated observer could discern. The agency instructs its
    agents to use the TRIG questions dynamically: they may be scrambled, added,
    removed, or rephrased in response to the specific situation that agents face.
    44
    to the extent that it required USCIS to disclose material reflecting the
    TRIG Questions.
    II.   Documents Withheld under FOIA Exemption 5
    ICE withheld under Exemption 5 a memo titled “ICE Ability to
    Use 212(a)(3)(C) Foreign Policy Charge.” The agency emphasizes that
    the memo was a draft, that it was not binding, and that it reflected the
    views of the individual author rather than the agency. ICE argues
    that the district court erred in holding that the ICE memo was not
    subject to the deliberative process privilege through Exemption 5.
    That exemption excludes from FOIA’s disclosure requirement “inter-
    agency or intra-agency memorandums or letters that would not be
    available by law to a party other than an agency in litigation with the
    agency.” 5. U.S.C. § 552(b)(5). “By this language, Congress intended
    to incorporate into the FOIA all the normal civil discovery privileges,”
    including the deliberative process privilege. Hopkins v. U.S. Dep't of
    Hous. & Urb. Dev., 
    929 F.2d 81
    , 84 (2d Cir. 1991). A record is protected
    45
    by the deliberative process privilege if it is (1) “predecisional, that is,
    prepared in order to assist an agency decisionmaker in arriving at his
    decision”; and (2) “deliberative, that is, actually related to the process
    by which policies are formulated.” 
    Id.
     (cleaned up). “[T]he
    deliberative process privilege protects only those records that bear on
    the formulation or exercise of policy-oriented judgment.” Nat. Res.
    Def. Council v. U.S. E.P.A., 
    19 F.4th 177
    , 184–85 (2d Cir. 2021) (internal
    quotation marks omitted). But the agency need not point to a specific
    decision that it was facing for which the document was prepared—it
    is enough that the record is connected to “a specific decisionmaking
    process.” 
    Id. at 192
    .
    It appears that ICE’s appeal with respect to the ICE memo
    might be moot, but the record is unclear. Although the district court
    concluded that the ICE memo did not fall within Exemption 5 because
    it was not pre-decisional, Knight II, 407 F. Supp. 3d at 345, it did not
    order immediate disclosure of the memo. Rather, it directed ICE to
    46
    “re-assess its applied exemptions” using the district court’s opinion
    as a guide “and disclose all responsive non-exempt materials that can
    reasonably be segregated from exempt materials.” Id. at 355. The
    record does not reveal whether or when ICE conducted the ordered
    segregability analysis. At oral argument, counsel for ICE stated that
    the agency had conducted a review and determined that no material
    was reasonably segregable, but it seemed that counsel might have
    been referring to a different memo that the district court had
    addressed in the same opinion. 11 While Knight now asserts that “ICE
    failed to disclose reasonably segregable portions of the Foreign Policy
    Provision Memo,” Knight Br. at 57, it did not raise that failure in the
    district court, nor has it filed its own cross-appeal.
    11Counsel explained that the district court ordered ICE to disclose anything in the
    memo that was “working law. ICE did that. ICE went through, did another
    review, and informed the plaintiffs that nothing in [the memo] contains working
    law.” Oral Argument at 36:59–37:09, Knight First Amend. Inst. at Columbia Univ. v.
    United States Citizenship & Immigr. Servs., No. 20-3837-cv (2d. Cir. Jan. 6, 2022). But
    the district court discussed “working law” in the context of a different ICE
    memo—the so-called “Extreme Vetting Memo” that is not at issue in this appeal.
    See Knight II, 407 F. Supp. 3d at 344.
    47
    Because we cannot determine whether ICE complied with the
    district court’s direction to conduct a segregability analysis, we
    remand to the district court to allow the parties to develop the record.
    On remand, if it has not already done so, ICE must conduct a
    segregability analysis and communicate its position with respect to
    the ICE memo to Knight. If ICE determines that it is not obligated to
    produce any further portions of the ICE memo, Knight is free to
    challenge that determination in the district court. The district court
    should consider any such renewed dispute in light of our decision
    expounding upon the deliberative process privilege in National
    Resources Defense Council, 
    19 F.4th 177
    , which we decided only after
    the district court issued its prior ruling. Should the court have doubts
    about the application of Exemption 5 to the ICE memo, it may also
    conduct an in camera review. And, of course, either party remains free
    to appeal anew in the face of an adverse ruling.

    CONCLUSION
    In sum, we hold as follows:
    (1) DOS properly withheld portions of 9 FAM under FOIA
    Exemption 7(E) because it established that the material was
    compiled for law enforcement purposes and that disclosure
    would reasonably risk circumvention of the law.
    (2) An agency need not show that the techniques or procedures
    of law enforcement that it seeks to protect from disclosure
    under FOIA Exemption 7(E) are special or technical before
    the Exemption applies, and material does not fall outside
    Exemption 7(E) solely because some targets of investigation
    could infer some of the contents of the material.
    Accordingly, USCIS properly withheld the TRIG questions
    under FOIA Exemption 7(E).
    (3) It is not clear from the record whether ICE has already
    complied with the segregability analysis ordered by the
    49
    district court with respect to the memo withheld pursuant
    to Exemption 5, and whether ICE’s appeal in that respect is
    now moot.
    We therefore REVERSE the orders of the district court to the
    extent that they required disclosure of the 9 FAM materials and the
    TRIG questions. We REMAND to the district court to allow the
    parties to more fully develop the record with respect to the ICE
    memo.
