Supreme Court hears birthright citizenship case that could test a 125 year old rule

"The Supreme Court will hear oral arguments on April 1, 2026 in Trump v. Barbara. The case challenges President Trump's executive order signed on January 20, 2025, his first day in office in his second term, which ended automatic citizenship for children born in the United States to parents who are undocumented or in the country on temporary visas such as student, tourist, or work visas. Every federal district court that has considered the order has ruled it unconstitutional, per SCOTUSblog.\n\nThe order has never taken effect due to immediate injunctions issued by multiple district courts. The case has drawn more than 50 amicus briefs from legal scholars, civil rights organizations, state attorneys general, and congressional members on both sides. A decision is expected by late June or early July 2026."

"The 14th Amendment to the U.S. Constitution, ratified in 1868, states: "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," per the National Archives. The controlling precedent interpreting that clause is United States v. Wong Kim Ark, decided by the Supreme Court in 1898.\n\nIn Wong Kim Ark, the Court ruled 6-2 that a child born in San Francisco to Chinese immigrant parents was a U.S. citizen, even though Chinese immigrants at the time were barred from naturalization under the Chinese Exclusion Act. The Court held that birth on U.S. soil, with very limited exceptions such as children of foreign diplomats, creates automatic citizenship regardless of the parents' nationality or legal status. That ruling has been the governing interpretation for 128 years."

"The Trump administration's core legal argument is that "subject to the jurisdiction thereof" in the 14th Amendment was intended to require complete political allegiance to the United States. Undocumented immigrants and temporary visa holders, the administration argues, owe only partial allegiance, which means their children are not born fully "subject to the jurisdiction" and do not automatically qualify for citizenship, per SCOTUSblog.\n\nThe challengers argue this directly contradicts Wong Kim Ark, which the Court explicitly applied to children of immigrants barred from naturalization, a situation that clearly involved people without full political allegiance. The challengers also note that the historical record from the 14th Amendment's drafters focuses on excluding only two categories from citizenship: children of foreign diplomats, who have formal diplomatic immunity from U.S. jurisdiction, and children of members of occupying armies."

If the Supreme Court agrees with the Trump administration, an estimated 255,000 babies born in the United States each year would no longer automatically receive citizenship, according to the Migration Policy Institute and Pew Research Center. Those children would be born stateless, since their parents' home countries may not recognize them as citizens if they were born outside those countries. The immediate practical impact would require the federal government to determine, at birth, whether each child's parents have sufficient legal status to convey citizenship, per the ABA.

The American Bar Association filed an amicus brief warning that eliminating birthright citizenship would cause significant legal chaos, affecting birth certificate systems, hospital reporting requirements, Social Security number issuance, passport applications, and state benefit programs. House Democrats filed a bicameral amicus brief arguing the order is unconstitutional under Wong Kim Ark.

"The case carries a second contested legal question: the scope of nationwide injunctions. In 2025, the Supreme Court limited the ability of single district courts to issue injunctions blocking executive orders nationwide. The birthright citizenship executive order has been blocked by multiple district courts issuing individual injunctions, which together cover the entire country, per SCOTUSblog.\n\nThe administration argued that even if the order is unconstitutional, the Court should rule that no single district court can block the order for anyone other than the named plaintiffs. That argument would mean that unless the Supreme Court strikes down the order on its merits, the administration could begin enforcing it for newborns who are not individually covered by the specific plaintiffs' injunctions. The Court may address both the merits of the citizenship clause and the scope of injunctive relief in its ruling."

"University of Minnesota law professor Ilan Wurman is arguing on behalf of the Trump administration's position at oral argument. Solicitor General John Sauer also appears for the United States. Several leading constitutional scholars filed amicus briefs challenging the administration's interpretation of the citizenship clause, including professors at Yale, Harvard, and the University of Chicago, per SCOTUSblog.\n\nThe current 6-3 conservative Supreme Court majority has shown willingness to reconsider long-standing precedents, including overturning Roe v. Wade in 2022 and limiting federal agency authority in several cases since. Whether five or more justices are willing to overrule or narrow Wong Kim Ark, a 128-year-old precedent, is the central unknown going into oral argument."

"The 14th Amendment was ratified in 1868 primarily to overturn the Supreme Court's 1857 Dred Scott ruling, which held that Black Americans could never be U.S. citizens. The citizenship clause was written broadly to ensure citizenship for all persons born on U.S. soil. The drafters specifically rejected language that would have limited citizenship to the children of citizens, per the National Archives.\n\nWong Kim Ark applied the clause's full breadth in 1898 in a case that involved Chinese immigrants who were specifically excluded from naturalization by federal law, which is analogous in many ways to today's undocumented immigrants. The Court's 1898 reasoning, if followed, would preclude the administration's current argument. Overruling Wong Kim Ark would require the Court to conclude that its 1898 interpretation was wrong."
