The Statutory Path: A Legal Strategy After Trump v. Barbara

Executive summary

Trump v. Barbara (2026) closed the executive path decisively and the direct judicial path presently. This paper maps what remains. Our conclusion, stated candidly: there is a real statutory path — the one Justice Kavanaugh’s concurrence identified — whose realistic near-term end is a well-built loss, and whose long-term value is a standing act of Congress awaiting a changed Court. Around it we propose an incremental ladder: six prospective steps, ordered from least to most constitutionally contested, each worth having on its own merits, each building the record for the next. The constitutional-amendment track runs in parallel, because it is the only outcome no future Court can revisit. Everything here is prospective only — no proposal NCI supports touches the citizenship of any person born before its effective date.

This is a work of legal strategy and advocacy. It assumes the analysis of our position paper and, like it, acknowledges Barbara as binding law unless and until it is confined, overruled, or superseded by amendment.

Background: what Barbara held — and what it left open

Chief Justice Roberts, writing for five justices, held that children born in the United States to parents unlawfully or only temporarily present “are citizens at birth” under the Fourteenth Amendment, reaffirming United States v. Wong Kim Ark (1898). Justice Kavanaugh concurred in the judgment only, resting solely on the citizenship statute, 8 U.S.C. § 1401: an executive order cannot override an act of Congress. He added that Congress “could amend” that law “or otherwise enact new legislation establishing exceptions to birthright citizenship for children born to foreign citizens unlawfully or temporarily in the country. But Congress has not yet done so.” Justice Thomas dissented, joined by Justice Gorsuch; Justice Alito dissented separately.

The constitutional alignment is therefore 5–1–3: five votes for the holding, three against, and one — the sixth vote for the judgment — expressly reserved on the constitutional question. That arithmetic is the single most important strategic fact after the holding itself.

What Barbara did not decide:

A statute was not before the Court. The case tested unilateral executive action against both the Constitution and an unamended § 1401. Justice Kavanaugh’s vote rested on the premise that the statute answers the question — which necessarily means a different statute presents a different question.
Categories of parents not before the Court — children of foreign-government employees who are not accredited diplomats; the traditional hostile-forces exception; births in unincorporated territories; and citizenship for births abroad, which is purely statutory.
The weight of a congressional record. What consideration a statute enacted on findings, hearings, and recorded votes would receive is an open question. The honest answer is likely “little on the constitutional merits” — but it is open.
Documentation and proof. Barbara establishes who is a citizen; it does not govern how citizenship and parental status are recorded at birth, which remain open to lawful, due-process-protected regulation.

Analysis

The Kavanaugh theory

If the sixth vote rested on § 1401 alone, then for at least one member of the Court the citizenship of these children currently rests on a statute — and what Congress grants by statute, Congress may prospectively narrow by statute. The concurrence does not merely tolerate that inference; it states it. A statute squarely presenting the constitutional question is therefore not defiance of Barbara — it is the completion of the analysis the concurrence deliberately left unfinished.

A statute is differently postured than the 2025 executive order in four ways. First, the unilateral-executive defect disappears: the order failed twice over, constitutionally for five justices and statutorily for a sixth, and the statutory defect is fully curable. Second, democratic legitimacy: an act of Congress arrives with findings, the 1866 record, and the presumption of constitutionality — courts approach striking down a statute differently than reviewing an order. Third, if any part of the majority’s reasoning leaned on the absence of congressional authorization or the impropriety of executive reinterpretation, a future Court could confine Barbara to executive action without overruling it — confinement is how the Court most often retreats. Fourth, a narrower statute presents a weaker case for the majority: Wong Kim Ark turned on parents with “permanent domicil and residence,” and a statute limited to children of short-term visitors sits at maximum distance from those facts.

Honest vote math

The three dissenters plus Justice Kavanaugh is at most four votes — and his is not committed. He took no position on the constitutional question; a justice who concluded the Fourteenth Amendment independently guarantees these children citizenship could vote to strike the statute too. His concurrence is an invitation to present the question, not a promise of the answer.

A fifth vote realistically comes from three sources: (a) composition change — the reason to enact the vehicle now, so the question is teed up whenever the Court changes rather than starting a legislative cycle afterward; (b) a majority justice whose vote was materially driven by the executive-unilateralism posture; or (c) the category itself — a temporary-visitor-only statute that even a justice unwilling to disturb the core holding might sustain by confining Barbara and Wong Kim Ark to parents with settled ties. The realistic near-term outcome of the full statute is reaffirmance of Barbara. We say so publicly. The statute’s value is not a quick win: it is the only vehicle by which the question can be re-presented, a standing enactment awaiting a changed Court, and the engine of the political case for the amendment.

Categories outside Barbara’s holding

Statutory action in five areas faces materially less constitutional risk:

Foreign-government personnel beyond accredited diplomats. The diplomatic exception is universally acknowledged and today implemented by regulation (8 C.F.R. § 101.3), not statute. Congress can codify it and rationally define its boundary. Small numbers — but it establishes the practice of Congress legislating Citizenship Clause exceptions.
The hostile-forces exception, equally traditional and never codified. One bright line: we do not endorse stretching “hostile forces” or “invasion” to cover unlawful migration generally — that argument persuaded no court in the 2025 litigation, and pressing it spends credibility for nothing.
Territorial birthright. Both circuits to decide the question have held the Citizenship Clause does not of its own force extend to unincorporated territories (Tuaua v. United States, D.C. Cir. 2015; Fitisemanu v. United States, 10th Cir. 2021, rehearing en banc and certiorari denied); citizenship there is statutory (8 U.S.C. §§ 1402–1407; § 1408 confers non-citizen national status for American Samoa — the very distinction Tuaua and Fitisemanu upheld). We use this line doctrinally, not legislatively: it proves a large body of birthright citizenship in American law is congressionally defined. We do not propose narrowing territorial citizenship — the territories are an argument, not a target.
Births abroad (jus sanguinis) are purely statutory (Rogers v. Bellei, 1971; Nguyen v. INS, 2001; Sessions v. Morales-Santana, 2017). Again chiefly doctrinal value: Congress routinely defines who is a “citizen at birth.”
Birth-tourism regulation at the visa stage. Regulating entry is not regulating citizenship. The State Department’s January 2020 rule (22 C.F.R. § 41.31) made travel for the primary purpose of obtaining citizenship for a child an impermissible B-visa purpose. Congress can codify and strengthen it with zero Citizenship Clause exposure.

The incremental ladder

Six prospective steps, least to most contested. Each stands on its own if the summit is never reached.

Codify birth-tourism entry restrictions. Statutory ineligibility, consular screening, penalties for commercial birth-tourism operations. Minimal risk; immediate effect; builds the factual record on the scale and structure of birth tourism.
Codify the settled exceptions (diplomats; hostile forces) in § 1401. Very low risk; replaces regulation with statute; establishes the institutional practice Rung 5 requires in a form no one can plausibly challenge.
Prospective tightening of jus sanguinis transmission rules where genuine policy needs support it. Low risk under Rogers v. Bellei; reinforces the premise that “citizen at birth” is, across much of the U.S. Code, a status Congress defines.
A uniform, due-process-protected birth-documentation framework — recording (not adjudicating) parental status in vital records, with presumptions in favor of the child, free documentation, notice-and-cure, and review. It must not condition any child’s citizenship on the record. This answers, in advance and in practice, the administrability objection that is the strongest practical argument against Rung 5 — and if it cannot be made to work accurately and humanely, that failure is a genuine reason to stop the ladder here, and we will say so.
Statutory exception: children of temporary visitors — the strongest test category, furthest from Wong Kim Ark’s facts, richest in equities from Rung 1’s record. Citizenship at birth where at least one parent is a citizen, national, lawful permanent resident, or lawfully present with settled ties (defined generously — long-term work and student visa holders qualify). High risk — Barbara covered temporary presence — and candidly a request that the Court confine the holding at its weakest point.
Statutory exception: children of unlawfully present parents — the core Barbara category, sequenced after or severably alongside Rung 5. Maximal risk; candidly what our position paper says it is: a request, through the one institution the concurrence identified, that the Court confine or reconsider Barbara.

Litigation design for Rungs 5–6: severability by category and application; a delayed effective date (births twelve or more months after enactment) so no child’s status is unsettled while review proceeds — or provisions effective only upon final judgment sustaining them; an express statelessness safeguard (any child who would otherwise be stateless is a citizen at birth); congressional findings carrying the 1866 record; and BCRA-style expedited review — a three-judge district court under 28 U.S.C. § 2284 with direct appeal to the Supreme Court, the model Congress used in the Bipartisan Campaign Reform Act and the Court accepted in McConnell v. FEC (2003). Because the United States defends its own statutes, test-case selection here means category sequencing in the statute itself — the drafting choices are the litigation strategy.

The amendment track, in parallel

The amendment stays on the table because it is the only outcome no future Court can revisit — and because the honest vote math above says the statutory track’s near-term ceiling is a well-postured loss. We propose: draft the amendment text now (short, expressly prospective, with the statelessness safeguard); build state-legislature memorializing resolutions into a visible, tracked count; and let the statutory fight do what it historically does — recorded votes, hearings, and, if Rungs 5–6 are struck down, the concrete demonstration that the people’s representatives enacted a policy the Constitution, as construed, forbids. That demonstration is what fuels amendments. (We take no position on an Article V convention strategy without separate analysis of the runaway-convention objection.)

Bright lines

These are conditions of the strategy’s legitimacy, stated publicly:

Prospective only — always. No proposal NCI supports may apply to any person born before its effective date. Afroyim v. Rusk (1967) forbids involuntary stripping of citizenship; every bill we support carries an express non-retroactivity clause.
No denaturalization expansion or documentation traps. Vance v. Terrazas (1980) and Maslenjak v. United States (2017) mark the due-process floor; we build above it.
A statelessness safeguard in every bill.
Due process in any documentation regime — presumptions favor the child; no child rendered undocumented by a records dispute.
Candor that Barbara is binding. Legislation and litigation are the constitutional methods of contesting precedent. We do not counsel, and will not associate with, executive or state defiance of the holding or of court orders.

What would change our mind

Candor is only credible if it is falsifiable, so we state the exits plainly:

If the documentation framework (Rung 4) cannot be made to work accurately and humanely in practice, that failure is a genuine reason to stop the ladder there — and we will say so.
If the Court reaffirms Barbara on the merits with a full statutory record before it, the statutory track is exhausted. We would say that too, and the work would continue on the amendment track alone.
If Congress enacts the statute and the Court sustains it, the constitutional amendment narrows to codifying what remains contested — or becomes unnecessary.

Counterarguments

We take the opposing case seriously.

Stare decisis. Barbara is a considered, recent constitutional holding; asking the Court to revisit it within years looks like attrition against precedent. Our response: constitutional stare decisis has always been the doctrine’s weakest form precisely because correction by amendment is so difficult — and the amendment process is being pursued in parallel. For one sitting justice the statutory question is genuinely undecided on his own stated terms; presenting it is not relitigating Barbara but litigating what its sixth vote reserved. If the Court reaffirms on the merits with a statutory record before it, the statutory track is exhausted and we will say so.
Wong Kim Ark’s breadth. Its common-law reasoning sweeps beyond its facts, and Barbara has now read it that way; the “permanent domicile” limitation is our gloss, twice rejected. Our response: conceded as a description of current law. Our claim is about original understanding and better reasoning — the accepted currency of constitutional contestation — and the temporary-visitor category is where the gloss is most defensible. We also note the countervailing authority honestly: Plyler v. Doe (1982) reasoned that unlawful presence does not remove a person from the Fourteenth Amendment’s “jurisdiction” for equal-protection purposes — a real obstacle, though addressed to a different clause and question.
Administrability. Conditioning citizenship on parental status means determinations at every birth, with errors falling on newborns. Our response: this is the strongest practical objection, which is why the documentation framework (Rung 4) precedes any status-based rule and must prove itself first. Peer democracies administer parentage-based rules, and the U.S. already administers parental-status rules for every birth abroad. If Rung 4 fails in practice, the ladder stops there.
Statelessness. Our response: every NCI-supported bill grants citizenship at birth to any child who would otherwise be stateless — a categorical answer at modest cost to the rule’s scope.
Punishing children for parents’ conduct. Our response: citizenship rules always turn on circumstances of birth the child did not choose — place, parentage, timing; jus sanguinis conditions children’s citizenship on their parents’ residence history today. Our proposal assigns the child the nationality of the parents rather than of the soil in defined cases; it denies no child a nationality and no person the protection of law. We make this response with restraint — the objection has moral force.
Feasibility. Rungs 5–6 require majorities and a signature; the amendment requires supermajorities that do not now exist. Our response: true, and our materials will never suggest otherwise. The ladder is designed so every rung yields real, defensible policy even if the summit is never reached — which is what distinguishes a strategy from a gesture.
