Why It Matters
The United States Supreme Court is hearing arguments this week in a case that could fundamentally alter how birthright citizenship is defined and applied across the country. The case centers on whether children born on U.S. soil to parents who are in the country illegally or on temporary visas are automatically entitled to American citizenship under the 14th Amendment — a legal question that has implications for immigration policy, federal benefits programs, and the administrative systems of every state.
A ruling in favor of narrowing birthright citizenship could affect hundreds of thousands of births in the United States each year and would represent one of the most significant changes to constitutional interpretation in over a century.
What Happened
The Supreme Court agreed to hear arguments in a challenge to President Donald Trump’s executive order, signed in January 2025, which directed federal agencies to stop recognizing birthright citizenship for children born in the U.S. to parents who are in the country unlawfully or on temporary, non-immigrant visas.
Multiple federal courts quickly blocked the executive order, ruling that it conflicted with the 14th Amendment to the U.S. Constitution. The administration appealed, and the Supreme Court agreed to take up the matter. While the court is technically reviewing the scope of the lower court injunctions — specifically whether nationwide injunctions were appropriate — the underlying constitutional question of birthright citizenship is central to the arguments being presented.
Oral arguments are taking place before all nine justices. The case consolidates legal challenges brought by a coalition of states as well as by immigrant rights organizations that sued to block the executive order from taking effect.
The Constitutional Question
The 14th Amendment, ratified in 1868, states that “all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” The current legal consensus, supported by a 1898 Supreme Court precedent in United States v. Wong Kim Ark, holds that virtually anyone born on U.S. soil is automatically a citizen.
The Trump administration argues that the phrase “subject to the jurisdiction thereof” excludes children of individuals who are not lawfully present in the country or who hold only temporary immigration status. Opponents of the order contend that the 14th Amendment’s text and more than 125 years of legal interpretation establish an unconditional right to citizenship by birth on U.S. soil.
By the Numbers
- An estimated 150,000 to 300,000 children are born annually in the United States to parents who are in the country without legal status, according to federal demographic research.
- The 14th Amendment has been in force for more than 157 years, with birthright citizenship considered settled law since the Wong Kim Ark decision in 1898 — a precedent now over 125 years old.
- More than 20 states joined lawsuits challenging the executive order at the district and appellate court levels before the cases reached the Supreme Court.
- At least three separate federal circuit courts issued injunctions blocking the order prior to Supreme Court review.
- The Supreme Court is expected to issue a ruling by the end of its current term in late June 2025.
Zoom Out
The United States is one of approximately 30 countries that practice unconditional birthright citizenship, a legal principle known as jus soli, or “right of the soil.” Most developed nations, including those in Europe and Asia, apply jus sanguinis — citizenship derived from the nationality of one’s parents — rather than place of birth.
The debate over birthright citizenship has surfaced periodically in Congress over the past three decades, with legislative proposals to limit it never advancing to a floor vote. The Trump administration’s use of an executive order to address the issue, rather than pursuing a constitutional amendment or legislation, is itself a point of legal contention before the court.
What’s Next
The Supreme Court is expected to issue its decision before the end of June 2025. If the court rules in favor of the administration, the executive order could take effect, potentially prompting immediate legislative and legal responses from states and advocacy organizations. A ruling against the administration would leave current birthright citizenship practices unchanged and could narrow the executive branch’s authority to reinterpret constitutional provisions unilaterally. Legal analysts across the spectrum have described this case as one of the most consequential before the court in the current term.
