    Before: Consuelo M. Callahan and Sandra S. Ikuta, Circuit
    Judges, and Cathy Ann Bencivengo,*** District Judge.
    Opinion by Judge Ikuta
    SUMMARY****
    Immigration
    On petitions for review brought by Ho Sang Yim,
    Orlando Velasquez Garcia, and Raul Borges Borba-Cardoso,
    the panel deferred to the Board of Immigration Appeals’
    interpretation of “perjury,” as used in the aggravated felony
    definition of 
    8 U.S.C. § 1101
    (a)(43)(S), and held that perjury
    under section 118(a) of the California Penal Code is an
    aggravated felony.
    Each of the three petitioners was convicted of perjury
    under section 118(a) of the California Penal Code and then
    suffered adverse immigration consequences on the ground
    that he had committed an aggravated felony under 
    8 U.S.C. § 1101
    (a)(43)(S), which includes “an offense relating to . . .
    perjury.”
    Applying the three-step categorical approach, the panel
    first explained that the BIA had interpreted the generic
    ***
    The Honorable Cathy Ann Bencivengo, United States District
    Judge for the Southern District of California, sitting by designation.
    ****
    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    4                        YIM V. BARR
    definition of “perjury” to require that an offender (1) make a
    material false statement (2) knowingly or willfully (3) while
    under oath or affirmation or penalty of perjury (4) where an
    oath is authorized or required by law. The panel deferred to
    the BIA’s determination, explaining that the BIA had
    surveyed the definitions of perjury recognized at common
    law, codified in state and federal statutes, and adopted by the
    Model Penal Code, and that the BIA reasonably settled on a
    definition compatible with those sources. The panel also
    rejected the argument that it was not reasonable for the BIA
    to omit a requirement that a statement be made in an official
    proceeding, explaining that the federal perjury statute
    supports the BIA’s omission of a “proceeding” requirement,
    and that the BIA was not bound to adopt the definition used
    by a majority of the states.
    At the second step of the categorical approach, the panel
    concluded that the elements of perjury under section 118(a)
    are: (1) a willful statement, (2) either (a) under oath in any of
    the cases in which the oath may be administered or (b) in
    writing under penalty of perjury in circumstances permitted
    by law, (3) of any material matter, and (4) which the person
    knows to be false.
    At the third step, the panel concluded that the elements of
    section 118(a) and the elements of the generic federal
    definition are a categorical match. First, the panel concluded
    that there was no meaningful difference between section
    118(a)’s requirement of “willful” intent and the BIA’s
    requirement of “knowingly or willfully.”
    Second, with respect to the false-statement requirement,
    Borba argued that a person could be convicted under section
    118(a) without making a literally false statement because
    YIM V. BARR                          5
    California law provides that an “unqualified statement of that
    which one does not know to be true is the equivalent to a
    statement of that which one knows to be false.” The panel
    rejected that argument, concluding that the phrase “false
    statement” in the BIA’s definition includes statements made
    by a declarant who is entirely ignorant of the statement’s
    truth or falsity.
    Third, the panel considered the contention that section
    118(a) criminalizes more conduct than the BIA’s generic
    definition because, in California, it is no defense that the
    accused did not know the materiality of the false statement.
    Rejecting that argument, the panel explained that the BIA’s
    definition is in accord with the uniform principle that the
    declarant need not know the statement is material.
    Finally, the panel considered the requirement that an oath,
    affirmation, or declaration under penalty of perjury be
    authorized or permitted by law. The panel rejected Yim’s
    contention that there is a difference between being
    “authorized by law,” as provided by section 118(a), and being
    “permitted by law,” as provided by the BIA’s generic
    definition. The panel explained that, even if there is some
    semantic different between the terms, Yim failed to establish
    a “realistic probability” that section 118(a) is applied more
    broadly than the generic offense.
    Petitioners also argued that the offenses are not a
    categorical match because California law recognizes two
    affirmative defenses to perjury that are not incorporated into
    the federal generic offense. The panel rejected this
    contention, explaining that the existence or non-existence of
    affirmative defenses is irrelevant to the categorical approach,
    6                       YIM V. BARR
    and that neither of the statutes relied on by petitioners alter
    the statutory definition set forth in section 118(a).

    OPINION
    IKUTA, Circuit Judge:
    We hold that the Board of Immigration Appeals (BIA)
    reasonably interpreted “perjury,” as used in 
    8 U.S.C. § 1101
    (a)(43)(S), to mean an offense where “an offender
    make[s] a material false statement knowingly or willfully
    while under oath or affirmation [or penalty of perjury] where
    an oath is authorized or required by law.” Matter of
    Alvarado, 
    26 I. & N. Dec. 895
    , 901 & n.11 (BIA 2016).
    Given this definition, we hold that perjury under section
    118(a) of the California Penal Code is an “aggravated felony”
    because it is “an offense relating to . . . perjury.” 
    8 U.S.C. § 1101
    (a)(43)(S).
    I
    This opinion addresses issues raised in three separate
    petitions for review: Yim v. Barr, No. 17-70624; Velasquez
    Garcia v. Barr, No. 17-70670; and Borba-Carodoso v. Barr,
    No. 17-70742. Each of the petitioners was convicted of
    perjury under section 118(a) of the California Penal Code and
    then suffered adverse immigration consequences on the
    ground that he had committed an “aggravated felony,”
    namely, an “an offense relating to . . . perjury.” 
    8 U.S.C. § 1101
    (a)(43)(S). The petitioners contend that perjury under
    section 118(a) is not an “aggravated felony” because it is not
    “an offense relating to . . . perjury.” 
    Id.
     We briefly
    summarize the facts relevant to each petition before
    addressing the petitioner’s arguments.
    8                       YIM V. BARR
    A
    Raul Borges Borba-Cardoso, a native and citizen of
    Portugal, was admitted to the United States as a lawful
    permanent resident in 1975. In 2004, Borba was convicted of
    perjury in violation of section 118(a) for testifying falsely
    during a judicial proceeding, and he was sentenced to three
    years in prison. The Department of Homeland Security
    (DHS) initiated removal proceedings on the ground that
    Borba had been convicted of an “aggravated felony.” An
    immigration judge (IJ) found Borba removable as charged,
    and the BIA affirmed.
    B
    Orlando Velasquez Garcia is a native and citizen of
    Guatemala. He came to the United States on June 18, 1990.
    Once here, he amassed a significant criminal record,
    including a conviction for perjury in violation of section
    118(a) for providing false information, under penalty of
    perjury, to the California Department of Motor Vehicles. In
    2009, DHS charged Velasquez as removable on the ground
    that he was an alien “present in the United States without
    being admitted or paroled, or who arrived in the United States
    at any time or place other than as designated by the Attorney
    General.” 
    8 U.S.C. § 1182
    (a)(6)(A)(i).
    An IJ found Velasquez removable as charged and denied
    Velasquez’s requests for asylum, cancellation of removal,
    withholding of removal, and protection under the Convention
    Against Torture (CAT). The IJ ruled that Velasquez’s perjury
    conviction was an “aggravated felony,” rendering him
    ineligible for asylum and cancellation of removal, and the IJ
    denied Velasquez’s requests for withholding of removal and
    YIM V. BARR                          9
    CAT protection on the ground that Velasquez had not made
    the requisite showing. The BIA affirmed.
    C
    Ho Sang Yim is a native and citizen of South Korea. He
    was admitted to the United States as a lawful permanent
    resident on June 3, 1983. In March 2010, Yim was arrested
    pursuant to a four-count complaint charging grand theft auto,
    identity theft, falsifying financial statements, and perjury.
    Yim, like Velasquez, was charged with providing false
    information, under penalty of perjury, to the California
    Department of Motor Vehicles. Yim eventually pleaded nolo
    contendere to one count of perjury in violation of section
    118(a), and in December 2011, DHS charged Yim as
    removable for having committed an “aggravated felony.” An
    IJ found Yim removable as charged, and the BIA affirmed.
    II
    The term “aggravated felony” covers “offense[s] relating
    to . . . perjury . . . for which the term of imprisonment is at
    least one year.” 
    8 U.S.C. § 1101
    (a)(43)(S). An alien
    convicted of an “aggravated felony” is removable, 
    8 U.S.C. § 1227
    (a)(2)(A)(iii), and is also ineligible for asylum,
    
    8 U.S.C. § 1158
    (b)(2)(A)(ii), (B)(i), and cancellation of
    removal, 8 U.S.C. § 1229b(a)(3). The question here is
    whether perjury under section 118(a) of the California Penal
    Code is “an offense relating to . . . perjury.” 
    8 U.S.C. § 1101
    (a)(43)(S). To answer this question, we apply the
    categorical approach from Taylor v. United States, 
    495 U.S. 10
                               YIM V. BARR
    575 (1990).1 The categorical approach prescribes a three-step
    process for determining whether an offense is an “aggravated
    felony.”
    First, we must identify the elements of the generic federal
    offense, Renteria-Morales v. Mukasey, 
    551 F.3d 1076
    , 1081
    (9th Cir. 2008), in this case, “perjury,” 
    8 U.S.C. § 1101
    (a)(43)(S). We “defer to the BIA’s articulation of the
    generic federal definition ‘if the statute is silent . . . and the
    BIA’s interpretation is based on a permissible construction of
    the statute.’” Renteria-Morales, 
    551 F.3d at 1081
     (quoting
    Parrilla v. Gonzales, 
    414 F.3d 1038
    , 1041 (9th Cir. 2005));
    cf. United States v. Garcia-Santana, 
    774 F.3d 528
    , 542–43
    (9th Cir. 2014). An interpretation is permissible so long as it
    is not “clearly contrary to the plain meaning of the statute.”
    Parilla, 
    414 F.3d at 1041
    .
    Second, we must identify the elements of the specific
    crime of conviction, Renteria-Morales, 
    551 F.3d at 1081
    ,
    here, section 118(a) of the California Penal Code, 
    Cal. Penal Code § 118
    (a). In doing so, we will “not defer to the BIA’s
    interpretation of state law,” Renteria-Morales, 
    551 F.3d at 1081
    , because the BIA “has no special expertise . . . in
    construing state . . . statutes,” Marmolejo-Campos v. Holder,
    
    558 F.3d 903
    , 907 (9th Cir. 2009) (en banc). To determine
    the elements of a state statute, “we may consider the
    interpretation of the statute provided by state courts.” United
    States v. Perez, 
    932 F.3d 782
    , 785 (9th Cir. 2019).
    1
    Because we conclude that all of the conduct criminalized by section
    118(a) constitutes “an offense relating to . . . perjury,” we need not apply
    the modified categorical approach. See, e.g., Shepard v. United States,
    
    544 U.S. 13
    , 25–26 (2005).
    YIM V. BARR                         11
    Third, we compare the statute of conviction to the generic
    federal offense to determine “whether the specific crime of
    conviction meets the . . . definition of an aggravated felony.”
    Renteria-Morales, 
    551 F.3d at 1081
    . Here, unlike in other
    cases, the state offense need not criminalize the same amount
    of conduct (or less) as the generic offense, because the INA
    refers to “an offense relating to . . . perjury.” 
    8 U.S.C. § 1101
    (a)(43)(S) (emphasis added); see, e.g., United States v.
    Sullivan, 
    797 F.3d 623
    , 638 (9th Cir. 2015); United States v.
    Sinerius, 
    504 F.3d 737
    , 743 (9th Cir. 2007). As we have
    recognized, the phrase “relating to,” when used in this
    context, indicates that Congress intended to “cover[] a range
    of activities beyond” just the generic offense. Albillo-
    Figueroa v. I.N.S., 
    221 F.3d 1070
    , 1073 (9th Cir. 2000).
    Therefore, the statute of conviction need only “stand[] in
    some relation, bear[] upon, or [be] associated with th[e]
    generic offense.” Sinerius, 
    504 F.3d at 743
    .
    A
    We begin with the first step of the categorical approach,
    which is to identify the elements of the generic crime of
    “perjury,” as it is used in 
    8 U.S.C. § 1101
    (a)(43)(S), with due
    deference to the BIA. See Renteria-Morales, 
    551 F.3d at 1086
    . We presume that Congress intended the terms of a
    statute, including a list of offenses, to have their
    “contemporary meaning.” Taylor, 495 U.S. at 598. The
    definition of the relevant offense in another section of the
    United States Code provides strong evidence as to Congress’s
    intent, given Congress’s presumed familiarity with that
    definition. See, e.g., Esquivel-Quintana v. Sessions, 
    137 S. Ct., 1562
    , 1570–71 (2017). Accordingly, the BIA may “rely
    to a significant degree on the Federal definition of an offense,
    where available.” Matter of M-W-, 
    25 I. & N. Dec. 748
    , 752
    12                           YIM V. BARR
    n.5 (BIA 2012) (citation omitted); see Renteria-Morales,
    
    551 F.3d at 1086
     (holding that “the BIA acted reasonably in
    deriving the definition of ‘obstruction of justice’ for purposes
    of § 1101(a)(43)(S) from the body of federal statutes
    imposing criminal penalties on obstruction-of-justice
    offenses”). Although probative, a parallel federal offense
    might not provide “the complete or exclusive definition” of
    a generic offense, Esquivel-Quintana, 
    137 S. Ct. at 1571
    ; cf.
    Garcia-Santana, 774 F.3d at 535, and so a multi-
    jurisdictional analysis “can be useful insofar as it helps shed
    light on the common understanding and meaning of the
    federal provision being interpreted,” even though undertaking
    such an analysis is “not required by the categorical
    approach,” Esquivel-Quintana, 
    137 S. Ct. at
    1571 n.3
    (citation omitted).2 In addition to state criminal codes, the
    Model Penal Code and scholarly commentary may shed light
    on the contemporary meaning of a term. See, e.g., Taylor,
    495 U.S. at 580; Garcia-Santana, 774 F.3d at 534.
    1
    Given our deference to the BIA’s definition of generic
    federal offenses, see, e.g., Renteria-Morales, 
    551 F.3d at 1081
    , we begin by recounting the development of the
    BIA’s definition of “perjury.” Before December 29, 2016,
    the BIA concluded that the federal perjury statute, 
    18 U.S.C. § 1621
    , established the generic definition of “perjury,” as
    used in 
    8 U.S.C. § 1101
    (a)(43)(S). See In Re Martinez-
    2
    To the extent we have implied that the categorical approach requires
    a multi-jurisdictional analysis, see, e.g., Garcia-Santana, 774 F.3d at 534,
    that guidance has been superseded by Esquivel-Quintana, 
    137 S. Ct. at
    1571 n.3. See Miller v. Gammie, 
    335 F.3d 889
    , 899 (9th Cir. 2003) (en
    banc).
    YIM V. BARR                         13
    Recinos, 
    23 I. & N. Dec. 175
    , 177 (BIA 2001). Because the
    BIA determined that the federal perjury statute and section
    118(a) of the California Penal Code were “essentially the
    same,” section 118(a) qualified as an “offense relating to . . .
    perjury.” 
    Id.
     We then held that this interpretation was not
    entitled to deference on the ground that the BIA had failed to
    perform a survey to determine the “contemporary usage” of
    the term “perjury.” Yim v. Lynch, 610 F. App’x 672, 673 (9th
    Cir. 2015). Accordingly, we remanded to the BIA with
    instructions that it survey definitions of perjury codified in
    state statutes, adopted by the Model Penal Code, and
    endorsed by scholarly commentary. See 
    id.
     at 672–73 (citing
    Garcia-Santana, 774 F.3d at 534).
    In a subsequent opinion, Matter of Alvarado, the BIA
    surveyed the sources mentioned above. 
    26 I. & N. Dec. 895
    ,
    898–900 (BIA 2016). It first looked to the common-law
    definition of perjury. 
    Id. at 898
    . “At common law, perjury
    was defined as ‘a crime committed when a lawful oath is
    administered, in some judicial proceeding, to a person who
    swears willfully, absolutely, and falsely, in a matter material
    to the issue or point in question.” 
    Id.
     (quoting 4 William
    Blackstone, Commentaries on the Laws of England, 136–37
    (1769)). The BIA reasonably recognized, however, that the
    common-law definition of perjury was merely a starting point
    for defining “perjury,” as used in 
    8 U.S.C. § 1101
    (a)(43)(S).
    See, e.g., Taylor, 495 U.S. at 593 (rejecting the argument that
    burglary carried its common-law meaning because “[o]nly a
    few States retain the common-law definition, or something
    closely resembling it”); Garcia-Santana, 774 F.3d at 539
    (rejecting the argument that “conspiracy” carried its common-
    law meaning because only a small minority of jurisdictions
    retained “the common-law definition of conspiracy,” which
    did not require an overt act).
    14                       YIM V. BARR
    The BIA then considered the Model Penal Code and
    explained that it “slightly expanded the common law
    definition of perjury by proscribing false statements made ‘in
    any official proceeding,’ not just those made in ‘judicial’
    proceedings.” Matter of Alvarado, 26 I. & N. Dec. at 898
    (citing Model Penal Code § 241.1(1) (1985)). Specifically,
    “[a] person is guilty of perjury . . . if in any official
    proceeding he makes a false statement under oath or
    equivalent affirmation, or swears or affirms the truth of a
    statement previously made, when the statement is material
    and he does not believe it to be true.” Model Penal Code
    § 241.1(1). The Model Penal Code broadly defines an
    “official proceeding” as “a proceeding heard or which may be
    heard before any legislative, judicial, administrative or other
    governmental agency or official authorized to take evidence
    under oath, including any referee, hearing examiner,
    commissioner, notary or other person taking testimony or
    deposition in connection with any such proceeding.” Model
    Penal Code § 240.0(4). Thus, by proscribing false statements
    made “in any official proceeding,” a perjury offense could
    occur “before any legislative, judicial, administrative or other
    governmental agency or official authorized to take evidence
    under oath.” Matter of Alvarado, 26 I. & N. Dec. at 898
    (quoting Model Penal Code § 240.0(4)).
    After consulting the Model Penal Code, the BIA
    explained that “States’ perjury laws have many similarities to
    the common law and Model Penal Code definitions.” Id. At
    the time the phrase “an offense relating to . . . perjury” was
    added to 
    8 U.S.C. § 1101
    (a)(43)(S) in 1996, the majority of
    states defined perjury to require, at the least, “(1) a material
    (2) false statement (3) made knowingly or willfully (4) while
    under oath, affirmation, or under penalty of perjury.” 
    Id.
    YIM V. BARR                              15
    (footnote omitted).3 In addition to these elements, the
    majority of states also “required that the witness take [an]
    oath in an ‘official proceeding,’ or in a proceeding where an
    oath was either ‘required or authorized by law.’” 
    Id. at 899
    (footnotes omitted) (collecting statutes).
    Finally, the BIA consulted the federal perjury statute,
    
    18 U.S.C. § 1621
    . 
    Id. at 900
    . In 1996, as now, the statute
    provided,
    Whoever—
    (1) having taken an oath before a competent
    tribunal, officer, or person in any case in
    which a law of the United States authorizes an
    oath to be administered, that he will testify,
    declare, depose, or certify truly, or that any
    written testimony, declaration, deposition, or
    certificate by him subscribed is true, willfully
    and contrary to such oath states or subscribes
    any material matter which he does not believe
    to be true; or
    (2) in any declaration, certificate, verification,
    or statement under penalty of perjury as
    permitted under section 1746 of title 28,
    3
    The BIA explained that “[s]ome States had a ‘knowing’ mens rea in
    their perjury statutes, while others included a ‘willful’ requirement.”
    Matter of Alvarado, 26 I. & N. Dec. at 898 n.5. But “these states of mind
    are not meaningfully distinguishable because courts have uniformly
    interpreted the willfulness requirement of perjury to mean that the
    defendant knowingly made the false statement.” Id. (citing Bronston v.
    United States, 
    409 U.S. 352
    , 359 (1973); Matter of Esqueda, 
    20 I. & N. Dec. 850
    , 858 (BIA 1994); Model Penal Code § 2.02(8)).
    16                      YIM V. BARR
    United States Code, willfully subscribes as
    true any material matter which he does not
    believe to be true;
    is guilty of perjury.
    Pub. L. No. 94-550, § 2, 
    90 Stat. 2534
    , 2534–35 (1976)
    (codified at 
    18 U.S.C. § 1621
    ). The federal statute, like some
    state statutes, broadly extends to “unsworn declarations
    prepared under penalty of perjury.” Scott Mah et al., Perjury,
    57 Am. Crim. Law Rev. 1115, 1117 (2020) (citing 
    18 U.S.C. § 1621
    (2)). The BIA reasonably “presume[d] that Congress
    was familiar with 
    18 U.S.C. § 1621
     when it enacted [
    8 U.S.C. § 1101
    (a)(43)(S)].” Matter of Alvarado, 26 I. & N. Dec.
    at 900 (citing Miles v. Apex Marine Corp., 
    498 U.S. 19
    , 32
    (1990)).
    Having surveyed the relevant authorities, the BIA
    concluded that “the generic definition of the term ‘perjury’ in
    [
    8 U.S.C. § 1101
    (a)(43)(S)] requires that an offender
    [1] make a material false statement [2] knowingly or willfully
    [3] while under oath or affirmation [or penalty of perjury]
    [4] where an oath is authorized or required by law.” 
    Id.
    at 901 & n.11. The definition “incorporates false statements
    made orally and in writing under penalty of perjury.” 
    Id.
    at 901 n.11. The BIA’s definition does not require that the
    relevant statement be made in a proceeding. 
    Id.
     at 899–900
    (footnotes omitted).
    We conclude that this is a “permissible construction of the
    statute.” Parrilla, 
    414 F.3d at 1041
     (citation omitted). The
    BIA surveyed the definitions of perjury recognized at
    common law, “codified in state and federal statutes,” and
    “adopted by the Model Penal Code,” Garcia-Santana,
    YIM V. BARR                               17
    774 F.3d at 534, and the BIA reasonably settled on a
    definition of perjury compatible with these sources. As such,
    the BIA’s definition of perjury is not “clearly contrary to the
    plain meaning of the statute.” Parrilla, 
    414 F.3d at 1041
    .
    Therefore, we defer to the BIA’s determination.
    2
    In arguing against this conclusion, Yim contends that it
    was not reasonable for the BIA to omit a requirement that a
    statement be made in an “official proceeding” or a
    “proceeding where an oath [is] either ‘required or authorized
    by law.’” To support this, Yim points to the fact that the BIA
    “identified only seven states as not requiring that the oath be
    made in a proceeding.”
    We reject this argument. First, the federal perjury statute,
    
    18 U.S.C. § 1621
    , supports the BIA’s omission of a
    “proceeding” requirement. Section 1621(2) provides that a
    person is guilty of perjury if he “willfully subscribes as true
    any material matter which he does not believe to be true” “in
    any declaration, certificate, verification, or statement under
    penalty of perjury as permitted under section 1746 of title 28,
    United States Code.” 
    18 U.S.C. § 1621
    (2).4 Section 1621(2)
    does not require that the statement be made in a
    “proceeding,” and the BIA could reasonably rely on
    
    18 U.S.C. § 1621
     “to discern the elements of generic
    4
    Section 1746 sets forth the required form for declarations under
    penalty of perjury when, “under any law of the United States or under any
    rule, regulation, order, or requirement made pursuant to law, any matter
    is required or permitted to be supported, evidenced, established, or proved
    by the sworn declaration, verification, certificate, statement, oath, or
    affidavit, in writing of the person making the same.” 
    28 U.S.C. § 1746
    .
    18                           YIM V. BARR
    perjury.” Matter of Alvarado, 26 I. & N. Dec. at 900 (citation
    omitted).5 In fact, it would be unreasonable for the generic
    definition of perjury to include a “proceeding” requirement,
    as Yim contends, because then conduct that meets Congress’s
    definition of “perjury” for 
    18 U.S.C. § 1621
    (2) would not
    constitute “perjury” under 
    8 U.S.C. § 1101
    (a)(43)(S). We
    typically interpret statutes in a way that avoids such
    incongruity. See Digital Equip. Corp. v. Desktop Direct, Inc.,
    
    511 U.S. 863
    , 879 (1994) (“[C]ourts should construe statutes
    . . . to foster harmony with other statutory and constitutional
    law.”). Thus, although the federal perjury statute might not
    supply the “complete or exclusive definition” of “perjury,”
    Esquivel-Quintana, 
    137 S. Ct. at 1571
    , it strongly supports
    the BIA’s decision to omit a proceeding requirement, see
    Renteria-Morales, 
    551 F.3d at 1086
     (holding that “the BIA
    acted reasonably in deriving the definition of ‘obstruction of
    justice’ for purposes of § 1101(a)(43)(S) from the body of
    federal statutes imposing criminal penalties on obstruction-
    of-justice offenses”).
    Second, in discerning Congress’s intent, the BIA may
    survey a variety of sources and it is not bound to adopt the
    definition of an offense used by a majority of the states.
    5
    To the extent Yim argues that the federal perjury statute, 
    18 U.S.C. § 1621
    , includes a proceeding requirement, he is mistaken. Section
    1621(2) extends to “unsworn declarations prepared under penalty of
    perjury,” Scott Mah et al., Perjury, 57 Am. Crim. Law Rev. 1115, 1117
    (2020) (citing 
    18 U.S.C. § 1621
    (2)), which do not need to be prepared in
    connection with a “proceeding,” see 
    28 U.S.C. § 1746
    ; United States v.
    Gomez-Vigil, 
    929 F.2d 254
    , 258 (6th Cir. 1991) (“Section 1746 authorizes
    the use of unsworn declarations under penalty of perjury, rather than
    sworn declarations under oath, whenever the law, rule, regulation, or order
    or requirement permits the matter to be supported, evidenced, established
    or proved by sworn declaration.”).
    YIM V. BARR                             19
    Indeed, the BIA need not in engage in a multi-jurisdictional
    analysis at all. Esquivel-Quintana, 
    137 S. Ct. at
    1571 n.3; cf.
    Garcia-Santana, 774 F.3d at 534. Here, the BIA reasonably
    placed significant weight on the federal definition of perjury,
    Matter of Alvarado, 26 I. & N. Dec. at 900, and confirmed
    the reasonableness of this choice by identifying a number of
    states that likewise do not include a “proceeding” requirement
    in their definition of perjury.6 The BIA reasonably
    considered these definitions as evidencing the
    contemporaneous understanding of the elements of perjury
    and bolstering its conclusion regarding congressional intent.
    See Estrada-Espinoza v. Mukasey, 
    546 F.3d 1147
    , 1152–53
    (9th Cir. 2008) (en banc) (bolstering its interpretation of the
    generic offense of “sexual abuse of a minor” by “survey[ing]
    current criminal law,” even though it was “unnecessary” to do
    so because Congress had defined “sexual abuse of a minor”
    in a parallel federal offense), overruled on other grounds as
    recognized by United States v. Rivera-Constantino, 
    798 F.3d 900
    , 904 (9th Cir. 2015).
    3
    Velasquez argues that the BIA’s interpretation is
    unreasonable because the BIA’s decision to “survey the
    contemporary definition of perjury [was] unexplained” and
    “there is no evidence that Congress intended anything other
    than the federal definition of perjury under 
    18 U.S.C. § 1621
    .” We reject these arguments. The BIA surveyed
    contemporary definitions of perjury because we told it to do
    6
    See 
    Alaska Stat. Ann. §§ 11.56.200
    , 11.56.240; 
    Ariz. Rev. Stat. Ann. § 13-2702
    ; 
    Cal. Penal Code § 118
    (a); 
    Iowa Code Ann. §§ 622.1
    ,
    720.2; 
    Nev. Rev. Stat. Ann. § 199.145
    ; R.I. Gen. Laws Ann. § 11-33-1;
    
    Tenn. Code Ann. § 39-16-702
    .
    20                      YIM V. BARR
    so, see Yim, 610 F. App’x at 672–73, and such a survey can
    “aid [the] interpretation” of a generic offense by “offering
    useful context,” see Esquivel-Quintana, 
    137 S. Ct. at
    1571
    n.3.
    4
    In sum, we “may not supply the interpretation of the
    statute we think best (as we would without an agency
    pronouncement)” and must instead ask whether the BIA’s
    interpretation of perjury was “based on a permissible
    construction of the statute.” Marmolejo-Campos, 
    558 F.3d at 908
     (quoting Chevron, U.S.A., Inc. v. Nat. Res. Def.
    Council, Inc., 
    467 U.S. 837
    , 843 (1984)). The BIA’s
    approach to determining the elements of the generic offense
    of perjury was consistent with Supreme Court guidance as
    well as our own: the BIA surveyed relevant sources and
    settled on a definition of perjury that was consistent with the
    federal perjury statute and a number of state criminal codes.
    Because the BIA’s definition is “not clearly contrary to the
    plain meaning of the statute,” Parrilla, 
    414 F.3d at 1041
    , we
    conclude that it is entitled to deference.
    B
    Having accepted the BIA’s definition of the generic
    offense, we now turn to the second step of the categorical
    approach and ascertain the elements of the state statute of
    conviction. Section 118(a) provides:
    [1] Every person who, having taken an oath
    that he or she will testify, declare, depose, or
    certify truly before any competent tribunal,
    officer, or person, in any of the cases in which
    YIM V. BARR                               21
    the oath may by law of the State of California
    be administered, willfully and contrary to the
    oath, states as true any material matter which
    he or she knows to be false, and [2] every
    person who testifies, declares, deposes, or
    certifies under penalty of perjury in any of the
    cases in which the testimony, declarations,
    depositions, or certification is permitted by
    law of the State of California under penalty of
    perjury and willfully states as true any
    material matter which he or she knows to be
    false, is guilty of perjury.
    
    Cal. Penal Code § 118
    (a).
    By its terms, section 118(a) criminalizes both oral and
    written perjury. Matter of Alvarado, 26 I. & N. Dec. at 901
    (citing Rivera v. Lynch, 
    816 F.3d 1064
    , 1071–72 (9th Cir.
    2016)). For oral perjury cases, the elements of a section
    118(a) offense are: “a [1] willful statement, [2] under oath,
    [3] of any material matter [4] which the witness knows to be
    false.” Rivera, 816 F.3d at 1072 (quoting Chein v. Shumsky,
    
    373 F.3d 978
    , 983 (9th Cir. 2004)).7 For written perjury
    cases, the false statement must be “in writing under penalty
    of perjury” in circumstances “permitted by law,” as opposed
    7
    See also Cal. Jury Inst. Crim. (CALJIC) No. 7.20 (“Every person
    who, [1] having taken an oath to (testify, declare, etc.) truly before any
    competent tribunal, officer, or person, in any of the cases in which the
    oath may by law be administered, [2] willfully and contrary to the oath,
    [3] states as true any material matter [4] which he or she knows to be
    false, is guilty of the crime of perjury in violation of Penal Code section
    118.”).
    22                           YIM V. BARR
    to “under oath.” Id.8 The other elements—willfulness,
    materiality, and falsity—remain the same.                See 
    id.
    Accordingly, the elements of perjury under section 118(a)
    are: (1) a willful statement, (2) either (a) under oath in any of
    the cases in which the oath may be administered or (b) in
    writing under penalty of perjury in circumstances permitted
    by law, (3) of any material matter, and (4) which the person
    knows to be false. See Rivera, 816 F.3d at 1072; CALJIC
    No. 7.20; CALJIC No. 7.21.
    C
    We now turn to the third step of the categorical approach.
    Given the language of 
    8 U.S.C. § 1101
    (a)(43)(S), we must
    determine whether perjury in violation section 118(a) of the
    California Penal Code “relat[es] to” the BIA’s generic
    definition of perjury. To do so, we begin, as we normally do,
    by determining whether the state offense is a categorical
    match with the generic offense, meaning that the state offense
    criminalizes the same amount of conduct (or less) as the
    generic offense. See Sullivan, 797 F.3d at 635. Once we
    complete this comparison, we turn to the question whether the
    state offense “relat[es] to” the BIA’s generic definition of
    perjury. See id. at 636; Sinerius, 
    504 F.3d at 743
    . Here, the
    petitioners direct our attention to four distinct elements:
    (1) intent; (2) false statement; (3) materiality; and
    (4) authorized or permitted by law.
    8
    See also CALJIC No. 7.21 (“Every person who [1] (testifies,
    declares, etc.) under penalty of perjury [2] in any of the cases in which
    (testimony, declarations, etc.) under penalty of perjury [are] permitted by
    law, [3] willfully states as true any material matter [4] which he or she
    knows to be false, is guilty of the crime of perjury in violation of Penal
    Code section 118.”).
    YIM V. BARR                          23
    1
    We begin with the intent element. Section 118(a) requires
    an intent of “willful[],” 
    Cal. Penal Code § 118
    (a), and the
    BIA’s generic definition of perjury require the intent of
    “knowingly or willfully,” Matter of Alvarado, 26 I. & N. Dec.
    at 902. Because there is no meaningful difference between
    “knowingly” and “willfully” in this context, the BIA’s use of
    both terms has no effect here. As the BIA explained, “courts
    have uniformly interpreted the willfulness requirement of
    perjury to mean that the defendant knowingly made the false
    statement.” Id. at 899 n.5 (citing Bronston, 
    409 U.S. at 359
    ;
    Matter of Esqueda, 20 I. & N. Dec. at 858; Model Penal Code
    § 2.02(8)).         “The terms ‘corruptly,’ ‘willfully,’
    ‘intentionally,’ and ‘knowingly’ are sprinkled freely through
    [perjury] statutes, as is the more helpful phrase, ‘not believing
    the statement to be true,’” but “[t]here does not appear to be
    a significant distinction among the statutes based on the use
    of these different terms.” Sara Sun Beale et al., Grand Jury
    Law & Practice § 11:6 (2d ed. 2019). Thus, we conclude that
    there is a match between the intent required by section 118(a)
    and the intent required by the BIA’s generic definition of
    perjury.
    2
    We next turn to the false-statement requirement. Both
    section 118(a) and the BIA’s generic definition of perjury
    require a false statement. The BIA’s generic definition refers
    to a “false statement,” Matter of Alvarado, 26 I. & N. Dec.
    at 901, whereas section 118(a) refers to a person “stat[ing] as
    true any . . . matter which he or she knows to be false,” 
    Cal. Penal Code § 118
    (a). These requirements are materially
    indistinguishable.
    24                       YIM V. BARR
    Arguing against this conclusion, Borba points to section
    125 of the California Penal Code, which provides, “An
    unqualified statement of that which one does not know to be
    true is equivalent to a statement of that which one knows to
    be false.” 
    Cal. Penal Code § 125
    . According to Borba, this
    means that a person can be convicted of perjury in violation
    of section 118(a) without making a literally false statement,
    and therefore section 118(a) criminalizes more conduct than
    the BIA’s generic definition of perjury.
    We disagree. The BIA’s definition of perjury inherently
    incorporates the longstanding common-law view that a
    witness gives false testimony if the witness states any matter
    as true when, in fact, the witness is entirely ignorant as to the
    matter. See 3 Edward Coke, Institutes of the Laws of
    England 166 (Brooke ed. 1797) (stating that two witnesses
    were guilty of perjury when they swore to the value of goods
    but “because they knew it not, it was a false oath in them, for
    . . . which both the . . . witnesses were sentenced in the star-
    chamber”). As one early commentator explained:
    It . . . is not to be material whether the fact
    which is sworn be in itself true or false; for
    howsoever the thing sworn may happen to
    prove agreeable to the truth, yet if it were not
    known to be so by him who swears to it, his
    offense is altogether as great as if it had been
    false, inasmuch as he wilfully swears, that he
    knows a thing to be true, which at the same
    time he knows nothing of, and impudently
    endeavours to induce those before whom he
    swears to proceed upon the credit of a
    deposition, which any stranger might make as
    well as he.

    1 William Hawkins, A Treatise of the Pleas of the Crown 433
    (8th ed. 1824); accord 2 Joseph Chitty, A Practical Treatise
    of Criminal Law 153–54 (Riley’s ed. 1819) (noting that if a
    witness “asserts that which may happen to be true, without
    any knowledge of the fact, he is equally criminal, and the
    accidental truth of his evidence will not excuse him”).
    The modern understanding of perjury incorporates the
    principle that a false statement includes an unqualified
    statement made without knowledge as to its truth or falsity.
    A number of states, like California, codified this principle,9
    while others confirmed it through judicial decisions.10 The
    federal perjury statute likewise incorporates this principle; it
    refers to statements of “any material matter which [the
    declarant] does not believe to be true,” 
    18 U.S.C. § 1621
    (1),
    (2), which covers “cases in which the witness makes a false
    statement without knowing whether the statement is true or

    reliable information on the subject, and for one to swear to a fact, of the
    existence of which he knows himself to be entirely ignorant, is rightly held
    to constitute perjury.”); Butler v. State, 
    429 S.W.2d 497
    , 502 (Tex. Crim.
    App. 1968) (“A witness may commit perjury if he swears to a matter
    about which he consciously has no knowledge. The effect of such
    testimony is that the witness declares that he knows the truth of what he
    states, and, if he is conscious he does not know it, he means to swear
    falsely.”).

    not,” Sara Sun Beale et al., Grand Jury Law & Practice § 11:6
    n.7 (2d ed. 2019). In short, “[a] person may be guilty of
    perjury when he swears to a particular fact, without knowing
    at the time whether it is true or false, or without having
    enough knowledge to support a belief that it is true, even
    though the statement is in fact true.” 4 Wharton’s Criminal
    Law § 577 (15th ed. 2019) (collecting sources). Borba has
    identified no authority casting doubt on this centuries-old
    principle.11
    Given this backdrop, we understand the phrase “false
    statement,” as used in the BIA’s generic definition of perjury,
    Matter of Alvarado, 26 I. & N. Dec. at 901, to include
    statements made by a declarant who is entirely ignorant as to
    the statement’s truth or falsity. Accordingly, we conclude
    that the reference to “false statement” in the BIA’s generic
    definition is the same as the reference to “false” statements in
    section 118(a), notwithstanding section 125.
    11
    Borba cites Bronston v. United States, 
    409 U.S. 352
     (1973), for the
    proposition that “[f]or a federal perjury charge . . . the statement cannot
    support a perjury conviction if the information is [true].” This is wrong.
    Bronston “consider[ed] a narrow but important question in the application
    of the federal perjury: whether a witness may be convicted of perjury for
    an answer, under oath, that is literally true but not responsive to the
    question asked and arguably misleading by negative implication.”
    
    409 U.S. at
    352–53. Thus, we have explained that “Bronston’s rule is
    limited to cases in which the statement is indisputably true, though
    misleading because it was unresponsive to the question asked.” United
    States v. Camper, 
    384 F.3d 1073
    , 1076 (9th Cir. 2004). Bronston
    therefore does not address the situation contemplated by section 125.
    YIM V. BARR                             27
    3
    We next turn to the element of “materiality.” Both
    section 118(a) and the BIA’s generic definition of perjury
    require that the statement be “material.” Although these
    terms are identical, Borba nevertheless contends that section
    118(a) criminalizes more conduct than the BIA’s generic
    definition because in California “[i]t is no defense to a
    prosecution for perjury that the accused did not know the
    materiality of the false statement made by him,” 
    Cal. Penal Code § 123
    , while, according to Borba, the BIA’s generic
    definition of perjury “likely” does not cover situations where
    a defendant lacks knowledge as to a statement’s materiality.
    We reject this argument. At common law, it was “not
    necessary that the witness know that the testimony is
    material,” 60A Am. Jur. 2d Perjury § 26 (2d ed. 2020)
    (collecting sources), and so “[a] mistaken belief that [a]
    statement was not material is not a defense to perjury,”
    110 Am. Jur. Proof of Facts 3d 479 (2009). The states
    uniformly adopted these principles, see, e.g., State v.
    Sargood, 
    68 A. 49
    , 50 (Vt. 1907) (“We are referred to no
    authority, and have seen none, that treats knowledge of the
    materiality as an element of [perjury].”), with many states,
    like California, codifying this understanding.12 The Model
    Penal Code is in accord. See Model Penal Code § 241.1(2)
    (“It is no defense that the declarant mistakenly believed the
    falsification to be immaterial.”). Borba cites no federal case
    that has interpreted the federal perjury statute, 
    18 U.S.C. § 1621
    , as requiring proof that a witness know that a false

    Mo. Ann. Stat. § 575.040

    statement is material, and we are aware of none. Cf. United
    States v. Schaier, 
    175 F. Supp. 838
    , 842 (S.D.N.Y. 1959)
    (“The defendant may be convicted even though he did not
    know that his statement was material.”). We therefore
    conclude that the BIA’s generic definition of perjury is in
    accord with the uniform principle that a declarant need not
    know that a statement is material to be guilty of perjury.
    Accordingly, we reject Borba’s argument that section 118(a)
    criminalizes more conduct than the BIA’s generic definition
    of perjury because California chose to codify this common
    law principle in section 125.
    4
    Finally, we consider the requirement that an oath,
    affirmation, or declaration under penalty of perjury be
    authorized or permitted by law. Section 118(a) refers to
    “cases in which [an] oath may by law of the State of
    California be administered” and situations where
    “certification is permitted by law of the State of California
    under penalty of perjury.” 
    Cal. Penal Code § 118
    (a). The
    BIA’s generic definition simply refers to the situation “where
    an oath is authorized or required by law.” Matter of
    Alvarado, 26 I. & N. Dec. at 901. Yim contends that there is
    a difference between a certification being “authorized by law”
    and being “permitted by law.”
    We disagree. Despite the slight difference in the verbal
    formulations in section 118(a) and the BIA’s generic
    definition, they are materially identical. To show that a
    statute criminalizes more conduct than a generic offense, a
    petitioner “must at least point to his own case or other cases
    in which the state court in fact did apply the statute in the
    special (nongeneric) manner for which he argues.” Gonzales
    YIM V. BARR                         29
    v. Duenas-Alvarez, 
    549 U.S. 183
    , 193 (2007). Here, Yim
    identifies no case in which a person was found guilty of
    violating section 118(a) when an oath was “permitted” but
    not “authorized” by law. Moreover, the California Court of
    Appeal has stated that an “authorized” oath is the same as an
    oath that is “permitted by law.” People v. Laws, 
    120 Cal. App. 3d 1022
    , 1034 (1981) (stating that a declaration in
    support of a motion “is a declaration for which an oath is
    ‘authorized,’ i.e., one which is ‘permitted by law’”). Thus,
    even if there is some semantic difference between “permitted
    by law” and “authorized by law,” Yim fails to show that there
    is a “realistic probability,” as opposed to a “theoretical” one,
    that section 118(a) is applied in a way that it is broader than
    the BIA’s generic offense. Duenas-Alvarez, 
    549 U.S. at 193
    .
    We therefore reject the argument that there is some
    meaningful difference between the phrases “authorized by
    law” and “permitted by law.”
    D
    Our analysis has thus far established that the elements of
    section 118(a) and the elements of the generic federal offense
    are a categorical match. The petitioners raise two final
    arguments against this conclusion. According to the
    petitioners, California law recognizes two affirmative
    defenses to perjury that are not incorporated into the federal
    generic offense, and so the offenses are not a categorical
    match. First, Borba argues that section 118(a) criminalizes
    more conduct than the BIA’s generic definition of perjury
    because section 122 provides that lack of competency is not
    a defense to a prosecution under section 118(a). Cal. Penal
    30                           YIM V. BARR
    Code § 122.13 Second, Velasquez argues that section 118(a)
    differs from the BIA’s generic definition of perjury because
    section 118(b) provides, “No person shall be convicted of
    perjury where proof of falsity rests solely upon contradiction
    by testimony of a single person other than the defendant.”
    
    Cal. Penal Code § 118
    (b).
    These arguments misunderstand the nature and effect of
    an affirmative defense. “Affirmative defenses are complete
    defenses that, once proven by the defendant, negate criminal
    liability for an offense, notwithstanding the government’s
    ability otherwise to prove all elements of that offense beyond
    a reasonable doubt.” United States v. Davenport, 
    519 F.3d 940
    , 945 (9th Cir. 2008). As we have recognized, the
    availability (or unavailability) of an affirmative defense “is
    not relevant to the categorical approach” because “we ‘look
    only to the fact of conviction and the statutory definition of
    the prior offense.’” United States v. Velasquez-Bosque,
    
    601 F.3d 955
    , 963 (9th Cir. 2010) (quoting Taylor, 495 U.S.
    at 602). The existence or non-existence of “extraneous
    affirmative defenses” is therefore “irrelevant to the
    categorical approach.” United States v. Albino-Loe, 
    747 F.3d 1206
    , 1213 (9th Cir. 2014).
    On its face, section 118(b) merely elaborates on the
    government’s evidentiary burden for proving perjury: proof
    of falsity may not rest “solely upon contradiction by
    testimony of a single person other than the defendant.” Cal.
    13
    Section 122 provides, “It is no defense to a prosecution for perjury
    that the accused was not competent to give the testimony, deposition, or
    certificate of which falsehood is alleged. It is sufficient that he did give
    such testimony or make such deposition or certificate.” 
    Cal. Penal Code § 122
    .
    YIM V. BARR                             31
    Penal Code § 118(b). As such, it does not change the
    elements of perjury set forth in section 118(a). Therefore,
    section 118(b) has no bearing on our analysis as to whether
    section 118(a) is a categorical match for the federal generic
    offense of perjury. See Rivera, 816 F.3d at 1069 n.1.
    Accordingly, we reject Velasquez’s argument.
    We next consider section 122, which provides that lack of
    competency is “no defense to a prosecution for perjury.” 
    Cal. Penal Code § 122
    . In California, the general rule is that
    “every person, irrespective of age, is qualified to be a witness
    and no person is disqualified to testify to any matter.” 
    Cal. Evid. Code § 700
    . But there is an exception for persons who
    are incompetent to testify. Under section 701 of the
    California Evidence Code, “[a] person is disqualified to be a
    witness if he or she is,” among other things, “[i]ncapable of
    understanding the duty of a witness to tell the truth.” 
    Cal. Evid. Code § 701.14
    14
    Section 701 provides, in full:
    (a) A person is disqualified to be a witness if he or she
    is:
    (1) Incapable of expressing himself or herself
    concerning the matter so as to be understood, either
    directly or through interpretation by one who can
    understand him; or
    (2) Incapable of understanding the duty of a witness to
    tell the truth.
    (b) In any proceeding held outside the presence of a
    32                        YIM V. BARR
    Section 122 prevents a defendant charged with perjury
    from raising the affirmative defense that the defendant did not
    “understand the duty of a witness to tell the truth.” 
    Cal. Evid. Code § 701
    (2). This limitation does not, however, alter the
    elements of the offense of perjury. The government must still
    prove beyond a reasonable doubt that the defendant stated “as
    true any material matter which he or she knows to be false,”
    
    Cal. Penal Code § 118
    (a), and the defendant may still negate
    the mens rea element of the offense by raising reasonable
    doubt as to whether he or she knew a statement was false, see,
    e.g., People v. Von Tiedeman, 
    120 Cal. 128
    , 136 (1898)
    (“[P]erjury cannot be willful where the oath is according to
    the belief and conviction of the witness as to its truth.”).
    Because eliminating a defense regarding lack of
    understanding about a witness’s duty does not cause section
    118(a) to criminalize more conduct than the generic offense
    of perjury, section 122 is irrelevant for purposes of applying
    the categorical approach. See Albino-Loe, 747 F.3d at 1213;
    Velasquez-Bosque, 
    601 F.3d at 963
    . Therefore, we also reject
    Borba’s argument.
    In sum, neither section 118(b) nor section 122 alter the
    “statutory definition of the . . . offense” set forth in section
    118(a), Velasquez-Bosque, 
    601 F.3d at 963
     (citation omitted);
    see Rivera, 816 F.3d at 1069 n.1, and so they have no bearing
    on our analysis here.
    jury, the court may reserve challenges to the
    competency of a witness until the conclusion of the
    direct examination of that witness.
    
    Cal. Evid. Code § 701
    .

    E
    Having considered the petitioners’ arguments, we
    conclude that section 118(a) of the California Penal Code is
    a categorical match with the BIA’s generic definition of
    perjury, meaning they cover the same amount of conduct.
    We therefore conclude that section 118(a) is an “offense
    relating to . . . perjury.”
