TOBY HEYTENS, Circuit Judge:
Under a now-repealed federal statute, certain children “born out of wedlock” and
lawfully present in the United States automatically became U.S. citizens if their mother
naturalized and “the paternity of the child ha[d] not been established by legitimation.”
8 U.S.C. § 1432(a)(3) (1952) (emphasis added). The question before us is whether
petitioner Mario Lopez’s “paternity” had been “established by legitimation” when his
mother naturalized. We conclude it had not. And because all agree that Lopez meets the
remaining requirements for derivative citizenship, he automatically became a U.S. citizen
upon his mother’s naturalization. We therefore grant the petitions for review, vacate the
underlying orders, and remand with instructions to terminate Lopez’s removal proceedings.
I.
Lopez was born in El Salvador in 1981 to unmarried parents. Although Mario Rene
Cabrera Cortez “declare[d]” himself to be Lopez’s father by signing the birth certificate,
Supp. JA 1290, Lopez claims he never lived with Cabrera Cortez and met him only a few
times. When Lopez was 11, he was admitted to the United States as a lawful permanent
resident to live with his mother, who had moved to this country two years earlier. When
Lopez was 16, his mother became a naturalized U.S. citizen.
As an adult, Lopez was convicted of two state-law drug crimes and sentenced to ten
years’ imprisonment. A few years before Lopez’s release, immigration officials
interviewed him in prison. Their official case memorandum stated that Lopez “derived
citizenship from his [U.S. citizen] mother as he was born out of wedlock and had not been
legitimized by the father.” Supp. JA 763.
2
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 3 of 23
Five years after Lopez was released from prison, however, the federal government
initiated removal proceedings against him. Lopez moved to terminate the proceedings,
arguing he automatically became a U.S. citizen when his mother naturalized and was thus
ineligible for removal. That motion generated a series of orders by an immigration judge
(IJ) and the Board of Immigration Appeals that eventually led to our review.
In 2017, the IJ issued an order denying Lopez’s motion to terminate the removal
proceedings. The IJ concluded Lopez could not “satisfy the requisite elements for
derivative citizenship” because he “failed to meet his burden to demonstrate that his
paternity was not legitimated under Salvadoran law.” Supp. JA 1855.
In 2018, the IJ ordered Lopez removed to El Salvador. In that order, the IJ
“incorporated” the earlier ruling that Lopez was not a U.S. citizen, Supp. JA 1124,
concluded Lopez’s criminal convictions rendered him removable, and denied his
application for deferral of removal under the Convention Against Torture (CAT). Lopez
appealed that decision to the Board.
In 2022, the Board dismissed Lopez’s appeal in part and “remanded” to the IJ “for
further proceedings and the entry of a new decision consistent with [the Board’s] opinion.”
Supp. JA 1051. In that decision—which we will call the 2022 Remand Order—the Board
“adopt[ed] and affirm[ed]” the IJ’s 2017 decision that Lopez was not a U.S. citizen and
“affirm[ed]” the IJ’s 2018 ruling that he was “removable.” Supp. JA 1050. But the Board
concluded the IJ erred in handling Lopez’s CAT claim and “remand[ed] the record for
additional fact-finding and the entry of a new decision regarding [that] claim.” Id.
On remand, the IJ again ordered Lopez removed and denied his request for relief
3
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 4 of 23
under the CAT. Lopez later claimed he did not receive a copy of the IJ’s order and, as a
result, did not immediately appeal it. In January 2023, immigration officials took Lopez
into custody to execute the IJ’s then‑administratively final removal order. The next day,
Lopez filed a motion asking the IJ to reopen his removal proceedings based on lack of
notice. The IJ granted that motion and, on January 25, 2023, the IJ once again “found
[Lopez] removable” and “re-entered” the removal order “as of th[at] date.” Supp. JA 812.
Seven months later, the IJ granted Lopez deferral of removal to El Salvador under the CAT.
Both Lopez and the government appealed to the Board.
In its next decision—which we will call the 2024 Remand Order—the Board
dismissed Lopez’s appeal, sustained the government’s appeal, and once again remanded to
the IJ “for further proceedings consistent with [the Board’s] opinion and entry of a new
decision.” Supp. JA 344. The Board concluded Lopez had “not established a reason to
revisit” its previous ruling that he did not obtain derivative citizenship through his mother.
Supp. JA 343. But the Board agreed with the government that the IJ had failed to
adequately explain the decision to grant CAT relief and “remand[ed] the record for further
proceedings on [Lopez’s] application for deferral of removal under the CAT.”
Supp. JA 344. Lopez filed a petition for review of the 2024 Remand Order, which is
docketed as No. 24‑1208 in this Court.
On remand, the IJ again ordered Lopez removed to El Salvador and again granted
deferral of removal under the CAT. Both sides appealed, and the Board dismissed the
appeals in a decision we will call the 2025 Dismissal Order. In that order, the Board
“reaffirm[ed]” its previous conclusion that Lopez was not a U.S. citizen. Supp. JA 11.
4
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 5 of 23
Lopez also petitioned for review of the 2025 Dismissal Order, which is docketed as
No. 25‑1076 in this Court. He is currently in immigration detention.1
II.
The Immigration and Nationality Act authorizes us to review “final order[s] of
removal.” 8 U.S.C. § 1252(a)(1). The government and Lopez agree there is a final order of
removal here but disagree about which of the Board’s orders merit that description.
Having reviewed the record, this Court’s precedent, and intervening Supreme Court
authority, we conclude the Board’s 2024 Remand Order was a final order of removal and
that we have jurisdiction in No. 24-1208. We therefore deny the government’s motion to
dismiss that petition for review. We also conclude we have jurisdiction in No. 25-1076
because the Board’s 2025 Dismissal Order expressly declined Lopez’s request to
reconsider the Board’s previous conclusion that he is removable.
A.
An order of removal is one “concluding that” a person “is deportable or ordering
deportation.” Riley v. Bondi, 606 U.S. 259, 267 (2025) (quoting 8 U.S.C.
§ 1101(a)(47)(A)). When, as here, an IJ makes the initial removability decision, such an
order becomes “final” when the Board makes “a determination . . . affirming such order”
or the time for seeking Board “review of such an order” expires, whichever happens first.
1
Lopez also sought habeas relief in the United States District Court for the Eastern
District of Virginia. The district court granted summary judgment to the respondents,
see Lopez v. Doe, No. 1:23-cv-68, 2024 WL 4304837 (E.D. Va. Sep. 25, 2024), and Lopez
appealed to this Court. That appeal (No. 24-6951) is being held in abeyance pending
resolution of these consolidated petitions for review.
5
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 6 of 23
8 U.S.C. § 1101(a)(47)(B). Our threshold question is thus when the Board “affirm[ed]” the
IJ’s conclusion that Lopez is removable from the United States. Id.
We conclude the first final order of removal in this case was the Board’s 2022
Remand Order. In 2018, the IJ ordered Lopez “removed from the United States to El
Salvador,” Supp. JA 1129, which was an order of removal. And in its 2022 Remand Order,
the Board expressly “affirm[ed] the Immigration Judge’s holding that” Lopez was
“removable” under two provisions of the Immigration and Nationality Act. Supp. JA 1050.
At that point, there was a final order of removal from which Lopez could have sought
judicial review.
Lopez, of course, did not petition for review at that point. (To be fair, as we will
explain later, the law in this area is in flux and this Court’s then-existing precedent
suggested such a petition would have been premature.) But we conclude there was a later,
superseding final order of removal from which Lopez properly sought judicial review.2
On January 25, 2023, the IJ granted Lopez’s motion to “reopen his removal
proceedings,” “vacate[d]” its earlier decision ordering Lopez removed from the United
States, and issued a new order “as of th[at] date” finding that Lopez was “removable” and
ordering his removal to El Salvador. Supp. JA 831 (first quote), 812–13 (second, third, and
fourth quotes). By its terms, that decision was a new “order of removal” because it
concluded Lopez was “deportable” and actually “order[ed]” his “deportation.” Riley,
2
Even if there were no superseding final order here, the 30-day time limit for filing
a petition for review is not jurisdictional and is thus subject to both waiver and forfeiture.
See Riley, 606 U.S. at 272–77.
6
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 7 of 23
606 U.S. at 267 (quotation marks removed). That new order, in turn, became final when
the Board, in its 2024 Remand Order, declined to revisit its previous rulings and
“dismissed” Lopez’s appeal. Supp. JA 344.3 We therefore have jurisdiction in
No. 24‑1208, which seeks review of the Board’s 2024 Remand Order.
That leaves No. 25-1076, which seeks review of the 2025 Dismissal Order. On first
view, that order does not seem to be a new final order of removal because—unlike in
2024—the IJ had neither granted a motion to reopen nor vacated its previous ruling that
Lopez was removable from the United States. Compare Supp. JA 125–36, with
Supp. JA 812–13. But even assuming that the 2025 Dismissal Order was not a final order
of removal, we conclude we have jurisdiction because the Board denied Lopez’s request
to reconsider the previous orders of removal. The Immigration and Nationality Act
“expressly contemplates” judicial “review of decisions refusing to reopen or reconsider”
final orders of removal. Mata v. Lynch, 576 U.S. 143, 147 (2015) (citing 8 U.S.C.
§ 1252(b)(6)); see also 8 U.S.C. § 1252(b)(9). The Board’s “reason” for denying such a
request “makes no difference to the jurisdictional issue.” Mata, 576 U.S. at 148. In its 2025
Dismissal Order, the Board once again rejected Lopez’s claim that he derived U.S.
citizenship through his mother and “reaffirm[ed]” its conclusion that he is removable from
3
We do not hold that any reference to removability—or even a reiteration of the
IJ’s previous conclusion that Lopez was removable—would have been enough to make the
IJ’s January 25, 2023, order a new order of removal. Instead, our holding rests on the fact
that the decision expressly vacated a previous decision ordering Lopez removed and
“re‑entered” a new order “as of th[at] date” that ordered his removal. Supp. JA 812. We
also do not decide whether the Board’s 2022 Remand Order actually authorized the IJ to
reopen the removability question or how our analysis might have changed had the Board’s
2024 Remand Order concluded the IJ had not been permitted to do so.
7
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 8 of 23
the United States. Supp. JA 11. That is enough to permit our review in No. 25-1076 as well.
B.
Despite agreeing we have jurisdiction in No. 25-1076, the government sees things
quite differently. In its view, the only final order of removal here is the 2025 Dismissal
Order and we must dismiss the petition for review of the 2024 Remand Order
(No. 24‑1208) for lack of jurisdiction. In so arguing, the government relies heavily on
Kouambo v. Barr, 943 F.3d 205 (4th Cir. 2019). Although we agree that decision supports
the government’s position, we conclude intervening Supreme Court authority has
abrogated Kouambo’s holding and reasoning.
The relevant facts of Kouambo are much like those here. An IJ concluded a
noncitizen was removable and denied his asylum application but nonetheless granted
withholding of removal. See Kouambo, 943 F.3d at 208. The noncitizen appealed the denial
of his asylum application to the Board, which dismissed the noncitizen’s appeal but
remanded to the IJ for additional proceedings related to the grant of withholding of
removal. See id. at 209. Without waiting “for the IJ to issue an order on remand,” the
noncitizen immediately petitioned for judicial review of the Board’s decision. Id.
This Court concluded there was no “final order of removal” and dismissed the
petition for review “on jurisdictional grounds.” Kouambo, 943 F.3d at 207, 209 (quotation
marks removed). Our opinion gave two primary reasons for this conclusion. First, the Court
stated that the jurisdictional statute’s “use of the term ‘final’ counsels against concluding
that an order of removal can be subject to judicial review prior to the conclusion of all
substantive proceedings on remand.” Id. at 212. Second, the Court reasoned that permitting
8
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 9 of 23
judicial review while proceedings were still ongoing before the IJ “would require us to
resolve these cases in fits and starts,” thus sacrificing “judicial efficiency” and creating a
bifurcated system of judicial review in which noncitizens may not be able to effectively
challenge decisions like the denial of withholding of removal. Id. at 211 (quotation marks
removed); see id. at 213–14.
We take the government’s point that Kouambo suggests we lack jurisdiction in
No. 24-1208 because the Board’s 2024 Remand Order contemplated further substantive
proceedings about Lopez’s request for CAT relief. But we conclude that Kouambo’s
holding and reasoning cannot be squared with—and have thus been abrogated by—the
Supreme Court’s later decisions in Nasrallah v. Barr, 590 U.S. 573 (2020), and Riley v.
Bondi, 606 U.S. 259 (2025).
Standing alone, Nasrallah would not have been enough to abrogate Kouambo.
See Short v. Hartman, 87 F.4th 593, 605 (4th Cir. 2023) (describing the “high bar” for
concluding that circuit precedent has been “overrule[d] or abrogate[d]” by intervening
Supreme Court authority); cf. Garcia v. Garland, 73 F.4th 219, 228 n.5 (4th Cir.
2023) (reiterating Kouambo’s jurisdictional rule after Nasrallah but before Riley, though
without discussing Nasrallah). The disagreement between the parties in Nasrallah did not
involve the meaning of “final order of removal,” or when or how a noncitizen may seek
judicial review of a removability determination. Instead, it involved “the scope of judicial
review of CAT orders for . . . noncitizens who have committed” certain crimes and whether
that scope incorporates limits Congress has placed on judicial review of the underlying
removability determination. Nasrallah, 590 U.S. at 576.
9
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 10 of 23
That said, much of the Supreme Court’s reasoning in Nasrallah is hard to square
with this Court’s reasoning in Kouambo. Whereas Kouambo focused on “the agency’s
decisionmaking process” as a whole, 943 F.3d at 213 (quotation marks removed),
Nasrallah was careful to distinguish between proceedings about removability (which
culminate in a final order of removal) and other proceedings. Nasrallah emphasized that
“[a] CAT order is not itself a final order of removal because it is not an order ‘concluding
that the alien is deportable or ordering deportation.’” 590 U.S. at 582 (quoting 8 U.S.C.
§ 1101(a)(47)(A)). The Court also stated that a CAT order neither “disturb[s]” nor
“affect[s] the validity of the final order of removal” because it does not prevent a noncitizen
from being removed from the United States. Id. That reasoning undermines this Court’s
conclusion in Kouambo that there can be no “final order of removal” until “the conclusion
of all substantive proceedings on remand.” Kouambo, 943 F.3d at 212; accord Kolov v.
Garland, 78 F.4th 911, 927–28 (6th Cir. 2023) (Murphy, J., concurring) (concluding
Nasrallah and a 2021 Supreme Court decision “seemingly reject” the reasoning of
decisions like Kouambo).
To be sure, Kouambo identified another justification for its holding: the desirability
of consolidating all judicial review of agency action into a single proceeding.
See Kouambo, 943 F.3d at 211–14. And “when a Supreme Court decision abrogates one
portion of our rationale in a prior case but not another, the rationale not abrogated by the
Supreme Court” continues to “bind[] future panels.” Taylor v. Grubbs, 930 F.3d 611, 619
(4th Cir. 2019). But we conclude the Supreme Court’s even more recent decision in Riley
abrogated the portions of Kouambo’s reasoning that survived Nasrallah.
10
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 11 of 23
Unlike Nasrallah—and like this case—Riley directly involved the meaning of the
words “final order of removal.” Riley, 606 U.S. at 263 (quoting 8 U.S.C. § 1252(b)(1));
accord id. at 266–72. Echoing this Court’s reasoning in Kouambo, the parties in Riley
identified various “practical problems” that would “arise if a removal order becomes final
before the issue of withholding-only relief is decided.” Id. at 271; cf. Kouambo, 943 F.3d
at 213–14. The Supreme Court rejected those arguments, emphasizing both the need to
“follow the statutory text” and identifying various ways to address the “legitimate practical
concerns” the parties had identified. Riley, 606 U.S. at 272. The Court also reiterated that
“[t]he finality of the order of removal . . . does not depend in any way on the outcome of ”
a later‑concluded “withholding-only proceeding.” Id. at 269 (alterations and quotation
marks removed).
We acknowledge the differences between the administrative processes underlying
Riley and those involved here. In Riley, a noncitizen reentered the country after being
removed and was subject to expedited removal proceedings in which his removal order
was issued by the Department of Homeland Security and could not be challenged in
proceedings before the IJ or the Board (both of which are housed in the Department of
Justice). See 606 U.S. at 264, 267. Here, in contrast, Lopez is in “ordinary removal
proceedings,” which afford him the opportunity to contest removability before the IJ and
the Board. Kolov, 78 F.4th at 924 (Murphy, J., concurring).
That said, we see no way to read Riley’s rejection of the efficiency- and fairness-
based arguments made in that case “harmoniously,” Taylor, 930 F.3d at 619 (quotation
marks removed), with this Court’s reasoning in Kouambo—much less the portions of
11
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 12 of 23
Kouambo’s reasoning that remained good law after Nasrallah. Cf. Riley, 606 U.S. at 269
(referencing “the lessons taught by Nasrallah”). Thus, while “we do not lightly presume
that the law of this circuit has been overturned,” Doe v. Sidar, 93 F.4th 241, 245 (4th Cir.
2024) (alterations and quotation marks removed), we conclude that high bar is satisfied
here. We hold that Nasrallah and Riley abrogated Kouambo and therefore deny the
government’s motion to dismiss No. 24-1208.4
III.
We now arrive at the merits question: Did Lopez automatically become a U.S.
citizen when his mother naturalized? We have jurisdiction to review that “question[] of
law.” 8 U.S.C. § 1252(a)(2)(D). And because we conclude there are no genuine issues of
material fact, we can—and must—decide the issue for ourselves. See § 1252(b)(5)(A) (“If
the petitioner claims to be a national of the United States and the court of appeals finds . . .
that no genuine issue of material fact about the petitioner’s nationality is presented, the
court shall decide the nationality claim.” (emphasis added)). Applying the traditional tools
of statutory construction, we conclude Lopez is a U.S. citizen. We therefore grant the
petitions for review, vacate the underlying orders, and remand with instructions to
terminate the removal proceedings against him. See, e.g., Ng Fung Ho v. White, 259 U.S.
4
We recognize that our holding represents a major change about when some
immigrants seeking CAT relief will need to file an initial petition for review, but that does
not mean we will need “to resolve these cases in fits and starts.” Kouambo, 943 F.3d at 211.
Rather, as the Supreme Court explained in Riley, even when a person files an immediate
petition for review from a final order of removal, this Court can await the conclusion of
any “withholding-only proceedings” and decide all issues at once. 606 U.S. at 272;
see 8 U.S.C. § 1252(b)(9) (zipper clause).
12
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 13 of 23
276, 284 (1922); Johnson v. Whitehead, 647 F.3d 120, 125 (4th Cir. 2011); cf. Frank v.
Rogers, 253 F.2d 889, 890 (D.C. Cir. 1958) (“Until the claim of citizenship is resolved, the
propriety of the entire proceeding is in doubt.”).
A.
The parties agree the relevant derivative-citizenship statute is the one in effect when
Lopez’s mother naturalized in 1998. See Jahed v. Acri, 468 F.3d 230, 234–35 (4th Cir.
2006) (analyzing a petitioner’s citizenship claim under a then-repealed statute that had been
in effect when the relevant parent naturalized); cf. Duarte-Ceri v. Holder, 630 F.3d 83, 87
(2d Cir. 2010) (“To determine whether a petitioner obtains derivative citizenship, the court
applies the law in effect when [the] petitioner fulfilled the last requirement to qualify.”
(alterations and quotation marks removed)). Because we will return to that statute’s
provisions several times, we begin by quoting it in full:
A child born outside of the United States of alien parents, or of an alien parent
and a citizen parent who has subsequently lost citizenship of the United
States, becomes a citizen of the United States upon fulfillment of the
following conditions:
(1) The naturalization of both parents; or
(2) The naturalization of the surviving parents if one of the parents is
deceased; or
(3) The naturalization of the parent having legal custody of the child when
there has been a legal separation of the parents or the naturalization of the
mother if the child was born out of wedlock and the paternity of the child has
not been established by legitimation; and if
(4) Such naturalization takes place while such child is unmarried and under
the age of eighteen years; and
(5) Such child is residing in the United States pursuant to a lawful admission
for permanent residence at the time of the naturalization of the parent last
naturalized under clause (1) of this subsection, or the parent naturalized under
clause (2) or (3) of this subsection, or thereafter begins to reside permanently
13
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 14 of 23
in the United States while under the age of eighteen years.
8 U.S.C. § 1432(a) (1952).5
The parties agree about most of the relevant questions under this statute. They agree
Lopez was born outside the United States to parents who were then both noncitizens. They
agree subsections (1) and (2) are inapplicable because only Lopez’s mother naturalized and
nothing in the record suggests his biological father is deceased. They also agree that
Lopez’s parents were never married, which makes subsection (3)’s first clause
inapplicable. Cf. Barthelemy v. Ashcroft, 329 F.3d 1062, 1065 (9th Cir. 2003) (concluding
subsection (3)’s first clause could not apply to a petitioner whose “natural parents never
married and thus could not legally separate” (emphasis removed)). For that reason, only
subsection (3)’s second clause remains in play. Further narrowing our inquiry, the parties
agree Lopez was born of out wedlock and that he satisfies subsections (4) and (5) because
he was unmarried, less than 18 years old, and a lawful permanent resident when his mother
naturalized.
So narrowed, this case comes down to a single controlling question: When Lopez’s
mother became a naturalized U.S. citizen in 1998, had his “paternity . . . been established
by legitimation” within the meaning of those terms in the then-governing federal statute?
We hold that it had not and that Lopez is therefore a U.S. citizen.
As always, we start with the statutory text. For Lopez to have automatically become
5
This statute was repealed in 2001 and replaced by a new one establishing different
rules for obtaining derivative citizenship. See Child Citizenship Act of 2000, Pub. L.
No. 106–395, §§ 101 & 103(a), 114 Stat. 1631, 1631–33 (2000).
14
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 15 of 23
a citizen when his mother naturalized, the relevant text instructs that a certain thing (“the
paternity of the child”) must not yet have “been established” in a certain way (“by
legitimation”). 8 U.S.C. § 1432(a)(3) (1952). The question is not whether the identity of
Lopez’s biological father was known when his mother naturalized or whether his birth had
been deemed ‘legitimate’ (as opposed to ‘illegitimate’) for some—or even all—purposes.
Instead, the question is whether Lopez’s paternity had then been established by
legitimation.
When the relevant statute was enacted, as now, the word “by” meant “through the
medium of,” “via,” or “through the agency or instrumentality of.” By, Merriam-Webster
Dictionary, https://www.merriam-webster.com/dictionary/by [https://perma.cc/4ETH-
YSMG] (citations removed). Congress’s use of “by” thus shows “that legitimation must be
the means through which paternity was established.” Flores‑Torres v. Holder,
680 F. Supp. 2d 1099, 1105 (N.D. Cal. 2009) (emphasis added).
To be sure, when Lopez was born, Mario Rene Cabrera Cortez signed the birth
certificate. But even assuming that act “established” Lopez’s “paternity,” we cannot see—
nor does the government explain—how signing a birth certificate establishes paternity “by”
a process United States law would have called “legitimation” when the relevant statute was
enacted in 1952. Cf. S. Rep. No. 81-1515, at 692–93 (1950) (“As a general proposition,
legitimation is accomplished by the marriage of the parents with acknowledgment of
15
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 16 of 23
paternity by the putative father.”).6 That alone is fatal to the government’s position.
B.
The government launches a flurry of counterarguments. We are unpersuaded.
1.
Relying on Berenyi v. District Director, Immigration and Naturalization Service,
385 U.S. 630 (1967), the government insists it is Lopez’s “burden to prove that he is a U.S.
citizen” and that “any doubts should be resolved in favor of” the government and against
him. Gov’t Br. 15–16 (quotation marks removed). It is, at minimum, unclear whether that
principle applies here. This is not “a naturalization case” and Lopez is not a “moving party”
who is “affirmatively” seeking relief in these proceedings. Berenyi, 385 U.S. at 636–37.
Instead, Lopez claims he is already a U.S. citizen and that the government is wrongfully
threatening to remove him despite that fact.
At any rate, we conclude it does not matter which side bears the burden of proof of
showing Lopez is or is not a U.S. citizen. The role of a burden of proof is to assign
responsibility for proving or disproving material facts that bear on the proper resolution of
a dispute. See, e.g., Smith v. United States, 568 U.S. 106, 112 (2013) (“Where the facts
with regard to an issue lie peculiarly in the knowledge of a party, that party is best situated
to bear the burden of proof.” (alterations and quotation marks removed)). Here there is no
dispute about what happened or whether the evidence that exists is enough to show that an
6
We do not hold that a later marriage is the only possible way to establish
“paternity . . . by legitimation” under former Section 1432(a)(3). Instead, our decision turns
on the absence of any act that established Lopez’s paternity by legitimation.
16
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 17 of 23
established legal standard (for example, “reasonable care”) has been satisfied. Instead, the
parties disagree about what the statutory words “the paternity of the child has not been
established by legitimation” mean. That is a purely legal question about which we must
exercise our own “independent judgment.” Loper Bright Enters. v. Raimondo, 603 U.S.
369, 412 (2024).
2.
The government’s next set of arguments involve an exegesis of Salvadoran family
law. The government starts by defining legitimation as “the act of placing a child born out
of wedlock in the same legal position as a child born in wedlock.” Gov’t Br. 18 (quoting
Matter of Moraga, 23 I. & N. Dec. 195, 197 (B.I.A. 2001) (en banc)). It next states that in
1983—two years after Lopez was born but 15 years before his mother naturalized—
El Salvador adopted a new constitution providing that all “children born in and out of
wedlock have equal rights.” Id. at 19. The government further represents that, under
Salvadoran law, “paternity can be established by voluntary recognition, including on the
birth certificate of the child.” Id. at 19–20 (alterations and quotation marks removed).
“Because Mr. Lopez’s father acknowledged paternity on [Lopez’s] birth certificate,” the
government insists Lopez automatically became “a legitimate child” when the new
Salvadoran constitution was adopted in 1983. Id. at 20.
We may assume—solely for the sake of argument—that the government is right
about everything in the previous paragraph. Even so, the government’s argument that those
changes in Salvadoran law bar Lopez from citizenship cannot be squared with the language
Congress chose.
17
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 18 of 23
We begin by emphasizing that our task is to interpret and apply the laws of the
United States. Like any other sovereign, El Salvador is free to keep, change, or abolish
legal distinctions between children born to married and unmarried parents, as well as create
rules for how a child’s paternity is determined for purposes of its own law. But whether
Lopez’s “paternity” had or had not “been established by legitimation” under former
Section 1432(a)(3) “is not ultimately governed by the law of [El Salvador], whatever that
may be.” JPMorgan Chase Bank v. Traffic Stream (BVI) Infrastructure Ltd., 536 U.S. 88,
98 (2002). As always, the meaning of terms used in a federal statute and how that meaning
applies in a particular situation are “matter[s] of federal law,” not Salvadoran law. United
States v. National Bank of Com., 472 U.S. 713, 727 (1985).
The government reads former Section 1432(a)(3) as imposing two separate
requirements—paternity and legitimation—that together rendered Lopez ineligible for
automatic citizenship. But that is not what the statute said. The statute did not say Lopez
was ineligible for citizenship so long as his paternity had been established and his
out‑of‑wedlock birth had later been legitimized. Instead, it said Lopez automatically
became a U.S. citizen when his mother naturalized so long his as his “paternity . . . ha[d]
not been established by legitimation.” 8 U.S.C. § 1432(a)(3) (1952) (emphasis added).
Even if Cabrera Cortez’s signature on the birth certificate established Lopez’s “paternity”
under either U.S. or Salvadoran law, it did not do so via or through a process of
“legitimation.” And even if later changes to Salvadoran law rendered Lopez’s birth
“legitimate” in some general sense, those changes “did not, of [their] own force, establish
[Lopez’s] paternity.” Lainez v. Bondi, 141 F.4th 393, 402 (2d Cir. 2025) (emphasis added).
18
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 19 of 23
The government’s contrary arguments either ignore the statutory text or change
“Congress’s chosen language in some material way.” Julmice v. Garland, 29 F.4th 206,
208 (4th Cir. 2022).7
3.
Plunging ahead, the government insists our sister circuits “widely agree with” it
(and its reading of the Board’s precedent) “on this issue.” Gov’t Br. 21. Not so. Each case
the government cites had materially different facts, interpreted materially different
statutory language, and/or was decided before the Supreme Court instructed federal courts
not to defer to administrative agencies like the Board about questions of statutory
interpretation. See Solis-Florez v. Bondi, 159 F.4th 205, 211 (4th Cir. 2025) (stating that,
after Loper Bright, “we no longer defer to the Board’s interpretation” of statutory terms).
Take the first case the government cites, the Ninth Circuit’s decision in
Romero‑Mendoza v. Holder, 665 F.3d 1105 (9th Cir. 2011). See Gov’t Br. 21 (describing
Romero‑Mendoza as “[p]articularly persuasive”). The government claims that “[t]he only
7
At points, the government suggests that the 1983 Salvadoran constitution’s
elimination of all distinctions between children born to married and unmarried parents was
itself sufficient to disqualify Lopez from derivative citizenship. That argument drifts even
further from the statutory text by eliminating the need to establish a child’s “paternity” via
any means. But see Lainez, 141 F.4th at 401 (“When Congress enacted the [Immigration
and Nationality Act] in 1952, it knew how to write provisions . . . such that certain
immigration consequences follow from a child merely being ‘legitimated.’” (citing other
provisions of the Act)). When asked about this problem, the government responded that
“El Salvador has already taken that part”—i.e., the need to establish paternity—“out of it
for us” by abolishing any distinctions between ‘legitimate’ and ‘illegitimate’ children.
Oral Arg. 28:52–:57. We return to the point we made earlier: Former Section 1432(a)(3)
was a law of the United States, and the government of El Salvador had no power to add to
or subtract from its requirements.
19
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 20 of 23
difference” between that case and Lopez’s is that, in Romero-Mendoza, the petitioner’s
“parents ultimately married.” Id. at 21 n.11 (emphasis added). But that difference is critical.
In Romero-Mendoza, the “parents’ subsequent marriage prior to [the petitioner’s] mother’s
naturalization” was what “established [his] paternity by legitimation.” 665 F.3d at 1108.
Here, there was no such marriage.
Other decisions cited by the government involved materially different statutory
language. For example, two involved a provision of the Immigration and Nationality Act
that asked whether a child was “legitimate” or had been “legitimated” rather than whether
the child’s paternity had been established by legitimation. De Los Santos v. Immigration &
Naturalization Serv., 690 F.2d 56, 58–60 (2d Cir. 1982); Lau v. Kiley, 563 F.2d 543, 544–
46 (2d Cir. 1977). And two other decisions involved a statutory provision whose text—
unlike this one’s—made clear that whether a person had been “legitimated under the law
of the person’s residence or domicile” and whether that person’s “paternity” had been
established were separate requirements that could be satisfied in different ways. 8 U.S.C.
§ 1409(a)(4) (1964); see Iracheta v. Holder, 730 F.3d 419, 423 (5th Cir. 2013) (construing
that provision); Anderson v. Holder, 673 F.3d 1089, 1097 (9th Cir. 2012) (same).
The government cites three other decisions that involved the same statute we
address here. But two of those cases were decided before Loper Bright and thus deferred
to the Board’s understanding of the relevant legal framework. See Miranda v. Sessions,
853 F.3d 69, 74 (1st Cir. 2017); Brandao v. Attorney Gen., 654 F.3d 427, 430 (3d Cir.
2011). The final decision—Colin-Villavicencio v. Garland, 108 F.4th 1103 (9th Cir.
2024)—was argued seven months before Loper Bright issued and decided only a month
20
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 21 of 23
later. And in that decision, the Ninth Circuit relied on its own pre-Loper Bright decisions
that had themselves deferred to the Board and repeatedly noted that the petitioner before it
“never disputed that her father’s paternity had been established by legitimation.”
Colin‑Villavicencio, 108 F.4th at 1114; see id. at 1112–13 (citing Romero‑Mendoza and
Anderson); see also Loper Bright, 603 U.S. at 412 (emphasizing pre-Loper Bright
decisions remain binding as a matter of “statutory stare decisis”). Those three decisions
are therefore of limited value here.
In contrast, we could not agree with the government’s position without creating a
circuit split. In Lainez v. Bondi, 141 F.4th 393 (2d Cir. 2025), the Second Circuit rejected
the same argument the government makes here and held the changes to Salvadoran law
that abolished all legal distinctions between children born to married and unmarried parents
“did not establish [the petitioner]’s paternity by legitimation.” Id. at 400. The government
argues Lainez is distinguishable because there the petitioner’s mother naturalized before
the Salvadoran civil code was amended to confirm that signing a child’s birth certificate is
a valid way of establishing paternity whereas here Lopez’s mother naturalized after that
change. But—for a final time—even assuming the government’s claims about Salvadoran
law are true, that would not matter. The issue before us is not whether, under the laws of
El Salvador, Lopez is a “legitimate” child whose “paternity” has been established in some
way. Rather, it is whether his “paternity” has or “has not been established by legitimation”
under the governing federal statute. 8 U.S.C. § 1432(a)(3) (1952) (emphasis added).
4.
The government’s final argument is that construing this since-repealed statutory
21
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 22 of 23
provision as meaning what it said would deprive that provision of real-world impact in
many situations. The government represents that many jurisdictions—not just El
Salvador—have abolished the traditional legal distinctions between ‘legitimate’ and
‘illegitimate’ children and have also eliminated any legal mechanism for establishing a
child’s paternity by legitimation. In such jurisdictions, the government asserts that
following the statutory text would defeat the statute’s “whole purpose” by leaving an
unmarried, noncitizen father with no way of protecting his parental rights by preventing
his child’s naturalization as a U.S. citizen. Oral Arg. 25:38–26:05.
That argument reprises a tactic the Supreme Court has repeatedly rejected. “[N]o
amount of policy-talk can overcome a plain statutory command.” Niz-Chavez v. Garland,
593 U.S. 155, 171 (2021). “[I]t is never our job to rewrite a constitutionally valid statutory
text under the banner of speculation about what Congress might have done had it faced a
question that, on everyone’s account, it never faced.” Henson v. Santander Consumer USA
Inc., 582 U.S. 79, 89 (2017). Rather, “our job” is “to apply faithfully the law Congress has
written.” Id.
Here, “it is entirely possible that Congress wrote a law in 1952 that assumed a world
in which ‘illegitimate’ children had to be ‘legitimated,’ and as the world moved away from
those distinctions, our law was a little slow to catch up.” Lainez, 141 F.4th at 403. But we
have no license to ignore the text of the law that Congress enacted and speculate about
what Congress would have wanted had it considered the possibility that some (or even
many) jurisdictions may later abolish all legitimacy-based distinctions. See Henson,
582 U.S. at 89. It is no more “a proper function of interpretation (as opposed to
22
USCA4 Appeal: 25-1076 Doc: 50 Filed: 02/13/2026 Pg: 23 of 23
amendment) to ensure” that every limitation that Congress placed on derivative citizenship
continues to apply to every country (no matter how that country alters its own family law)
than it is to ensure “that every development in foreign law has a corresponding benefit
under U.S. law.” Wedderburn v. Immigration & Naturalization Serv., 215 F.3d 795, 798
(7th Cir. 2000). Instead, we “must presume that a legislature says in a statute what it means
and means in a statute what it says there.” Connecticut Nat’l Bank v. Germain, 503 U.S.
249, 253–54 (1992). And based on what Congress said here, Lopez automatically became
a U.S. citizen when his mother naturalized.
