On June 30, 2026, the U.S. Supreme Court, in Trump v. Barbara, struck down President Donald Trump's executive order seeking to limit birthright citizenship and affirmed that nearly everyone born on U.S. soil becomes a citizen regardless of the parents' immigration status — subject to narrow historical exceptions. Below: exactly what the Court held, how it got there, how this differs from last year's ruling on judicial injunctions, and what it means in practice.
In brief
By a 6–3 vote, the Supreme Court held Executive Order 14160 unlawful and left birthright citizenship in place.
The key holding rests on the Constitution (the Fourteenth Amendment) with five justices — meaning ordinary legislation cannot change the rule.
The order never took effect; for those born in the U.S., a birth certificate remains sufficient proof of citizenship.
Current status as of July 2026. Trump v. Barbara (No. 25-365) was decided on June 30, 2026: Executive Order 14160 was struck down and birthright citizenship continues as before. Because the majority grounded its ruling in the Fourteenth Amendment, the rule can be changed only by a constitutional amendment or a new Supreme Court decision.

What the Supreme Court ruled
The Court held that children born in the U.S. to parents who are present unlawfully or temporarily fall within the Fourteenth Amendment's Citizenship Clause and are citizens at birth. Trump's order, which sought to exclude such children, was held unconstitutional. The ruling affirmed the lower court's decision (District of New Hampshire) and the line taken by every court that had previously considered the question.
What birthright citizenship is
Birthright citizenship (Latin jus soli, "right of the soil") is the principle by which a person becomes a citizen of a country by the fact of being born on its territory, regardless of the parents' citizenship or status. Put simply: if a child is born in the U.S., that child is a U.S. citizen at birth. The U.S. is one of several dozen countries — mostly in North and South America, including Canada, Mexico, and Brazil — where this rule is expressly established.
Separately, jus sanguinis ("right of blood") applies: citizenship passes to the child of a U.S. citizen even when born abroad. These are different bases; the Court's ruling concerns jus soli specifically.
The Fourteenth Amendment and Wong Kim Ark: a short history
The basis for the rule is the Citizenship Clause of the Fourteenth Amendment to the U.S. Constitution (ratified in 1868): "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."
The amendment was adopted after the Civil War to overturn Dred Scott v. Sandford (1857), which had denied citizenship to Black Americans. In 1898, in United States v. Wong Kim Ark, the Supreme Court applied the clause to a child born in San Francisco to parents who were subjects of China, holding that a person born on U.S. soil is a citizen even if the parents were not. That holding remained the settled understanding for more than a century. Citizenship for Native Americans was separately secured by the Indian Citizenship Act (1924).
Historically, only a narrow set of exceptions was recognized — chiefly the children of foreign diplomats (and, in the past, children of hostile occupiers); today the one that matters in practice is the children of diplomats.
Executive Order 14160: what it proposed
Executive Order 14160, "Protecting the Meaning and Value of American Citizenship," was signed by President Trump on January 20, 2025, the first day of his second term. It provided that children born in the U.S. to parents present unlawfully — or lawfully but temporarily (on a visa) — would not receive automatic citizenship. More precisely, the order covered children whose mother was present unlawfully, or lawfully but temporarily, and whose father was neither a U.S. citizen nor a lawful permanent resident (LPR).
The order was to take effect 30 days later, around February 19–20, 2025, but never did: federal courts across the country blocked its enforcement as unconstitutional. According to the Migration Policy Institute, the order would have affected roughly 250,000 children a year.
How the case reached the Supreme Court: two different rulings
It is important not to confuse two Supreme Court rulings that are often conflated.
Trump v. CASA (June 27, 2025). Here the Court decided not the citizenship question but the powers of the lower courts. By a 6–3 vote it held that federal district courts generally may not issue "universal" (nationwide) injunctions binding everyone in the country; such an injunction should extend only to those who sued. The constitutionality of birthright citizenship itself was not at issue then.
Trump v. Barbara (June 30, 2026). After the CASA ruling, a class action was filed in New Hampshire on behalf of all children the order would affect. On July 10, 2025, Judge Joseph Laplante issued a preliminary injunction protecting that class. The administration went to the Supreme Court directly (September 26, 2025); the Court took the case on December 5, 2025, heard argument on April 1, 2026, and on June 30, 2026 affirmed the lower court — this time on the merits.
How the justices voted
The overall vote was 6–3 to strike down the order, but the Court split on the reasoning.
Constitutional majority (5 votes): Chief Justice John Roberts, joined by Justices Sotomayor, Kagan, Barrett, and Jackson. They held that the Fourteenth Amendment itself guarantees birthright citizenship. Roberts relied on Wong Kim Ark and the common-law rule (jus soli).
Brett Kavanaugh concurred in the result but on a different basis: in his view the order violates a federal statute (8 U.S.C. §1401(a)), not the Constitution, and Congress could in principle create new exceptions.
Dissents: Clarence Thomas (the principal dissent, joined by Gorsuch), along with separate opinions from Samuel Alito and Neil Gorsuch.
Because the majority grounded its decision in the Constitution rather than a statute, there is a direct consequence: the rule cannot be changed by ordinary legislation.
The parties' arguments
The dispute turned on the meaning of the words "subject to the jurisdiction thereof" in the Fourteenth Amendment.
The plaintiffs (and the majority that agreed with them) took the view that "jurisdiction" here is geographic: it extends to everyone born on the country's territory, save for narrow exceptions (children of diplomats and the like), and does not depend on the parents' status or intentions. Wong Kim Ark, in their view, confirms this directly.
The administration argued for "domicile": birthright citizenship supposedly presupposes the parents' lawful permanent residence, which unlawful migrants and holders of temporary visas lack. In dissent, Thomas developed the domicile theory and Alito a theory of "allegiance" solely to the United States. The majority rejected these arguments, noting that the historical record of the amendment's ratification does not support a domicile requirement.
What the ruling means in practice
Executive Order 14160 is invalid and does not apply. The rule is unchanged: a person born on U.S. soil is a citizen at birth.
A U.S. birth certificate remains sufficient proof of citizenship.
The rule applies to children regardless of whether the parents are present unlawfully or on a temporary visa; the exceptions are narrow (chiefly the children of foreign diplomats).
Whom the ruling does not affect, and what has not changed
The ruling concerns only birthright citizenship (jus soli). It does not affect:
naturalization — obtaining citizenship through the established process (residence, exam, oath);
green cards and how they are obtained;
visas and visa categories;
the citizenship or status of the parents themselves — these are not changed by the child's birth.
Nor has anything changed in how a child born in the U.S. confirms status and obtains documents:
getting a Social Security number (SSN);
obtaining a U.S. passport;
getting a birth certificate and registering the birth with the state.
The process here is the same as before: a child born on U.S. soil is a citizen, and the birth certificate remains proof of that.
Can birthright citizenship now be abolished
After the ruling, President Trump called on Congress to limit birthright citizenship by statute. However, because the Court's constitutional majority derived the right directly from the Fourteenth Amendment, legal scholars note that an ordinary federal statute cannot override a constitutional provision. Changing the rule would require a constitutional amendment (a demanding process requiring approval by two-thirds of Congress and three-quarters of the states) or the Supreme Court's reconsideration of its position in the future.
Whom it affects
The ruling primarily affects children born each year in the U.S. to noncitizen parents — an estimated 250,000 a year — and their families. For the broader public, the ruling means that proof of citizenship still rests on the fact of birth on U.S. soil, not on a check of the parents' status.
The bottom line
Trump v. Barbara neither expanded nor narrowed the right to birthright citizenship — it affirmed the understanding of the Fourteenth Amendment that has stood for more than a century and rendered an attempt to change that rule by executive order legally untenable. If the practice ever changes, it will most likely be only through a constitutional amendment or a new Supreme Court precedent.
