Supreme Court Deals Trump a Major Loss — Birthright Citizenship Is Here to Stay

If you were born in the United States, this ruling is about the legal foundation of your citizenship — and for hundreds of thousands of babies born here every year, it just got a major defense.

The Supreme Court handed President Trump a significant defeat on June 30, 2026, blocking his attempt to rewrite one of the most fundamental rules in American law: that if you're born on U.S. soil, you're a U.S. citizen. The Court blocked Trump's contentious attempt to limit citizenship at birth for those born on U.S. soil, delivering a major blow to his agenda.

Here's the backstory: The case stems from an executive order Trump signed on his first day of his second term in January 2025, declaring that children born to parents who are in the United States illegally or temporarily are not American citizens. Under Trump's plan, children born in the U.S. to temporary visitors, those on student visas or work permits, or undocumented immigrants would not be citizens at birth.

The Court wasn't having it. The court, divided 6-3, ruled the executive order was unlawful. Five justices said it fell afoul of the Constitution's 14th Amendment, which has long been interpreted to bestow birthright citizenship on almost anyone born in the U.S. One justice, conservative Brett Kavanaugh, said the order violated federal law but not the Constitution.

Chief Justice John Roberts wrote the majority opinion, leaning hard on history. Roberts said that children born to parents who are in the United States unlawfully or temporarily are "born in the United States" and "subject to the jurisdiction thereof." He also pointed to a precedent that's over 125 years old: the Supreme Court, in an 1898 ruling called United States v. Wong Kim Ark, ruled that a man born in San Francisco to parents who were both from China was a U.S. citizen. Roberts noted the arguments Trump made were essentially the same ones that lost back then.

On the other side, three conservative justices dissented. In a separate dissent, Alito said the ruling "preserves a powerful incentive to enter or remain in this country illegally," adding that it saddles the U.S. with a "medieval rule" defining citizenship. In a 91-page dissent — more than three times as long as Roberts' opinion — Justice Thomas argued the 14th Amendment "was designed and understood to secure equal rights for the freed blacks."

The real-world stakes here are enormous. An estimated 255,000 children born every year to noncitizen parents would have lost legal status under the order, according to the Migration Policy Institute. Some may have faced difficulty establishing citizenship in any country, effectively being born as "stateless." And it wasn't just undocumented immigrant families at risk — while Trump has largely focused on illegal immigration in his rhetoric and actions, the birthright restrictions also would have applied to people who are legally in the United States, including students and applicants for green cards.

Importantly, the executive order has never been in effect — lower courts quickly blocked it after Trump signed it. So there's been no change to how citizenship works for babies born here. That stays the same.

Trump is not giving up quietly. Trump and some of his congressional allies quickly said they believed one path was to pass a law including the same provisions as his defeated order. But with the current makeup of Congress, that legislation would be dead on arrival. With a majority ruling that the executive order ran afoul of the 14th Amendment, a constitutional amendment would most likely be necessary to achieve Trump's goal — and that's a towering bar to clear, requiring two-thirds of Congress and three-fourths of states.

House Speaker Mike Johnson said Congress is considering both a constitutional amendment and legislation in response to the ruling. But legal experts are skeptical. As one legal commentator put it: "Congress could change the statutory question, but that doesn't defeat the fact that there were still 5 votes from this court saying that the Constitutional mandate is what it is."

Bottom line: birthright citizenship survives, the order never took effect, and the legal path to changing it just got a lot harder for the administration.
