The U.S. Supreme Court upheld birthright citizenship and rejected an executive order by President Donald Trump seeking to end automatic citizenship for children of undocumented migrants [1].

The ruling preserves a fundamental pillar of American immigration law by ensuring that citizenship remains tied to birth on U.S. soil rather than the legal status of parents. This decision prevents the administration from unilaterally altering the legal status of millions of people born in the United States.

In a six-three decision [1], the justices ruled that the executive order was unconstitutional. The Court said the order conflicted with the long-standing interpretation of the 14th Amendment, which guarantees citizenship to all persons born in the U.S. [1, 2].

Chief Justice John Roberts and the associate justices said that the precedent for birthright citizenship has existed for 150 years [1]. The Court found that the President lacks the authority to override the constitutional guarantee through an executive order, a move that would have stripped citizenship from children of undocumented migrants and temporary-visa holders [1, 2, 3].

The ruling follows a period of intense legal debate over the scope of presidential power regarding immigration. The court's decision reaffirms that the 14th Amendment provides a clear and absolute mandate that cannot be circumvented by administrative policy [2].

The decision was delivered on a Tuesday in June 2025 [2]. While some reports indicated the court had only agreed to hear the appeal, the final ruling confirms the rejection of the administration's position [1, 2].

“The Court said the executive order was unconstitutional because it conflicted with the 14th Amendment.”

This ruling reinforces the judiciary's role in limiting executive overreach regarding constitutional interpretations. By upholding the 14th Amendment, the Court ensures that birthright citizenship remains a legal certainty, preventing a shift toward a system where citizenship is determined by parental lineage or visa status, which would have fundamentally altered the demographic and legal landscape of the U.S.
