Trump v. Barbara
The Supreme Court ruled that children born on U.S. soil are American citizens at birth even if their parents are undocumented immigrants or only temporarily in the country, striking down President Trump's executive order that tried to deny them citizenship.
The 6-3 decision (with a further split over the reasoning) preserves more than a century of understanding that birth on American soil, not a parent's immigration status, determines citizenship, though several justices wrote separately urging a narrower or different approach.
“A child born on American soil and subject to American law was made an American citizen.”
The majority's core statement of the rule linking birthplace and citizenship.
How it got here: A New Hampshire federal court certified a nationwide class and blocked the order; the Supreme Court took the case before the First Circuit could rule, bypassing the normal appeals process.
The Case in Depth
What happened
President Trump issued an executive order in January 2025 declaring that children born in the United States to parents who are unlawfully or only temporarily present are not entitled to citizenship. Several immigrant parents, including pregnant women from Honduras, Taiwan, and Brazil, sued on their own behalf and their children's, arguing the order violated the Fourteenth Amendment and federal immigration law.
The question before the Court
Does the Constitution guarantee citizenship to children born in the United States to parents who are in the country illegally or only temporarily?
The Court's answer
The Constitution does not let the government deny citizenship to children born on U.S. soil just because their parents are undocumented or only temporarily present. The Court ruled that the Fourteenth Amendment's Citizenship Clause carried forward a long-standing rule that birth within the country's territory, combined with being subject to its laws, is enough to make someone a citizen at birth, with only narrow historical exceptions for children of foreign diplomats and members of sovereign Indian tribes.
The Court rejected the government's argument that a child's parents must be domiciled here or hold a certain immigration status for the child to qualify. It found no solid historical evidence that the Fourteenth Amendment's framers intended such a limit, and read its own 1898 Wong Kim Ark precedent as confirming the broader rule. As a result, President Trump's executive order excluding these children from citizenship was struck down as unconstitutional.

Why it matters
Millions of children already born in the United States to undocumented or temporarily present parents keep their citizenship, and future children born here will too, regardless of executive action. Hospitals, schools, and government agencies can continue treating any child born on U.S. soil as a citizen without new bureaucratic screening based on parents' immigration status.
What changes now
The executive order's exclusions from birthright citizenship are unconstitutional and remain permanently blocked nationwide, and the case is not being sent back for further fact-finding on the constitutional question. This is a final merits ruling, not a temporary order, though several justices suggested Congress could still legislate around the edges of immigration policy without altering who the Constitution itself makes a citizen at birth.
What this does not decide
The Court resolved a facial challenge to the executive order, meaning it addressed the order's core exclusions broadly. It did not resolve every possible narrower dispute — for example, Justice Gorsuch flagged unresolved questions about whether long-term undocumented residents count as legally domiciled, an issue courts may still need to sort out case by case.
Concurrences and dissents
How the Justices voted
Majority (5). Justice Roberts (author), joined by Justice Sotomayor, Justice Kagan, Justice Barrett, and Justice Jackson.
Dissent (4). Justice Kavanaugh (author), joined by Justice Gorsuch.
Concurrence — Justice Jackson
Justice Jackson, joined by Justice Sotomayor only as to the introduction and Part I, argued the Fourteenth Amendment was not a narrow racial 'spot treatment' for freed slaves but a universalist, antisubordination transformation of the whole Constitution. She traced how Black activists at 19th-century Colored Conventions argued for citizenship on universal birthright grounds rather than as a race-specific remedy, and criticized Justice Thomas's dissent as wrongly treating the Amendment as protecting only formerly enslaved people and those in analogous circumstances.
Dissent in part — Justice Kavanaugh
Justice Kavanaugh agreed the executive order is unlawful, but only because it violates a federal statute, 8 U.S.C. §1401(a), not the Constitution. He would have decided the case on that narrower statutory ground, and argued that Wong Kim Ark's four exceptions to birthright citizenship are not a permanently closed set; Congress could add new exceptions for children of unlawfully or temporarily present parents by amending the statute, though it has not yet done so.
Dissent — Justice Thomas
“The Citizenship Clause was enacted for people who were born in this country and called it home.”Thomas's central objection that citizenship should depend on a parent's domicile.
Justice Thomas argued that both the 1866 Civil Rights Act and the Fourteenth Amendment required not just birth in the U.S. but domicile here, and that historical practice for decades after ratification confirms children of temporary foreign visitors were not citizens. He would treat Wong Kim Ark as limited to parents actually domiciled in the country and would uphold the executive order's application to temporary visitors and at least some undocumented immigrants.
Dissent — Justice Alito
Justice Alito argued the Citizenship Clause requires that a person's allegiance run exclusively to the United States, not partly to a foreign power, and that Wong Kim Ark's actual holding was limited to children of parents permanently domiciled here. He warned the majority's rule could grant citizenship to children with no meaningful ties to America, while urging Congress, not the courts, to address the humane treatment of children already raised here.
Dissent — Justice Gorsuch
Justice Gorsuch largely joined Justice Thomas's reasoning but wrote separately to stress that the case was a facial challenge, which fails if the executive order has any lawful application — such as to children of temporary visitors. He questioned, however, whether the order could lawfully apply to children of parents who have long made the U.S. their permanent home despite lacking legal status. Read the full dissent →
How the Court got there
The legal reasoning, step by step
- The Court traced the English common-law rule of jus soli, under which anyone born within the sovereign's territory owed natural allegiance and became a subject at birth, with only narrow exceptions for lands outside the sovereign's control, temporarily lost territory, and diplomats.
- It found that this common-law rule crossed into early America and was rejected only by Dred Scott v. Sandford, which the Reconstruction Congress and the Fourteenth Amendment's Citizenship Clause were designed to repudiate by writing the common-law criteria — birth in the country plus being subject to the government's power — directly into the Constitution.
- Interpreting the phrase 'subject to the jurisdiction thereof,' the Court relied on Chief Justice Marshall's account in Schooner Exchange v. McFaddon of a nation's 'full and complete power' over everyone within its territory, finding that power waived only for narrow categories like foreign diplomats and members of quasi-sovereign Indian tribes — not for people present unlawfully or briefly.
- The Court read United States v. Wong Kim Ark, a 1898 decision, as confirming this common-law-based rule and rejecting any requirement that a child's parents be citizens or hold any particular immigration status for the child to be a citizen at birth.
- The Court rejected the government's proposed rule that citizenship depends on a parent's domicile or a heightened form of allegiance, concluding that the ratification-era historical record contains no real evidence Congress meant to impose such a limit, and that later scholarship promoting a domicile theory could not override the Constitution's text and original understanding.
