US Supreme Court upholds birthright citizenship and blocks Trump's bid to end it

The Supreme Court ruled 6-3 on June 30 that birthright citizenship remains protected under the Fourteenth Amendment, striking down President Donald Trump’s executive order that sought to deny citizenship to some children born in the United States.

Chief Justice John Roberts wrote the majority opinion, according to AP reporting. The decision blocks the administration’s effort to narrow who is recognized as a U.S. citizen at birth and preserves the long-standing legal understanding tied to the Constitution’s Citizenship Clause.

The ruling is a major setback for Trump and for supporters of his immigration crackdown. It also settles, for now, a high-stakes constitutional fight over whether children born on U.S. soil can be denied citizenship because of their parents’ immigration status.

How the case got here

Trump signed the executive order after returning to office in 2025, as part of a broader immigration push. The order sought to end birthright citizenship for some children born in the U.S. to undocumented immigrants or temporary visitors.

Lower courts had already blocked the order before the case reached the Supreme Court. The justices then left those blocks in place and rejected the administration’s bid to end birthright citizenship through executive action.

That sequence matters because it shows the administration did not succeed in changing the rule by decree, and the Court’s decision now makes clear that the constitutional question cannot be resolved that way.

What the Court said

The majority relied on the Fourteenth Amendment and the precedent associated with United States v. Wong Kim Ark, the 1898 case that has long been understood to protect citizenship for nearly all people born on U.S. soil.

The confirmed facts in the case point to a straightforward bottom line: children born on U.S. soil are citizens regardless of whether their parents are undocumented or temporarily present. That preserves the long-standing reading of the Citizenship Clause.

The decision also reinforces the limits of presidential power on immigration and citizenship. Any attempt to change birthright citizenship now would require a much broader legal or constitutional path than an executive order.

The split on the bench

The ruling exposed sharp divisions among the justices. Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented.

Justice Brett Kavanaugh agreed with the outcome but did not fully join the constitutional reasoning, according to AP. That left Roberts writing for a majority that preserved the status quo while still revealing internal disagreement over how the Court should explain it.

The split matters because it suggests the Court was united on the immediate result even if not on every legal theory behind it. For future disputes, that could shape how far the administration or Congress can push on related immigration questions.

Political fallout

Trump criticized the ruling and suggested Congress could try to act instead. His response signaled that the issue is likely to remain part of the broader immigration fight even though the Court has settled the constitutional question for the near term.

The case affects immigration policy, civil rights and the legal status of children born in the United States. It also has immediate practical implications for families who could have been affected by the order, including people navigating birth records, passports and other citizenship documentation.

Supporters of birthright citizenship quickly framed the ruling as a reaffirmation of a core constitutional protection. Reaction coverage on June 30 also highlighted praise from the great-grandson of Wong Kim Ark, whose case remains central to the precedent the Court relied on.

What happens next

The most likely next phase is political rather than judicial. Congress could face pressure to advance legislation, but the research packet does not show any realistic path that would avoid major legal and constitutional obstacles.

The White House or the Justice Department could issue additional post-ruling guidance, but no formal administrative instructions were confirmed in the available reporting. That leaves some implementation questions open even as the core legal rule is now settled.

For now, the Court’s decision keeps in place the rule that children born in the United States are citizens, regardless of whether their parents are undocumented or temporarily present. It also narrows the administration’s options as it continues its broader immigration agenda.

The case is likely to remain a touchstone in debates over immigration, civil rights and the meaning of being born in the United States.
