The Supreme Court is now weighing a question that has been mostly dormant for generations: who counts as an American citizen at birth. The justices will hear arguments over President Donald Trump’s executive order aimed at narrowing birthright citizenship, a move his team says is meant to preserve the meaning and value of U.S. citizenship and to curb abuses like birth tourism.
The case concerns Executive Order 14160, “Protecting the Meaning and Value of American Citizenship,” and whether the president can reinterpret the Citizenship Clause of the 14th Amendment. The clause reads, “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,” and the administration argues judges have misread its scope for more than a century.
Trump signed the order to deny automatic citizenship to those born after February 19, 2025 to parents who are in the country unlawfully or only on temporary visas. The order also directs federal agencies not to issue or accept documents that recognize citizenship for those children, and it frames citizenship as “a priceless and profound gift” that has been stretched beyond its intended meaning.
The Justice Department told the high court that lower courts got this wrong, saying those rulings rested on a “mistaken view” with potentially “destructive consequences.” “The lower courts’ decisions invalidated a policy of prime importance to the president and his administration in a manner that undermines our border security,” John Sauer, U.S. Solicitor General, said as he prepares to argue the case in person.
“Those decisions confer, without lawful justification, the privilege of American citizenship on hundreds of thousands of unqualified people,” Sauer added, framing the order as a necessary fix to an exploited policy. Supporters stress that enforcing a stricter rule protects national sovereignty and stops industries built around bringing foreign nationals here solely to give a child American citizenship.
Opponents call the plan unprecedented and unconstitutional, warning it would immediately affect roughly 150,000 births a year to noncitizen parents and millions of children raised with undocumented parents. The ACLU and other advocacy groups have charged that the president is trying to “unilaterally rewrite the 14th Amendment,” and they argue courts have consistently rejected the administration’s approach.
“The federal courts have unanimously held that President Trump’s executive order is contrary to the Constitution, a Supreme Court decision from 1898, and a law enacted by Congress,” said ACLU legal director Cecillia Wang, who will argue for the plaintiffs in the courtroom session. Plaintiffs — including families and immigrant-rights coalitions — seek to protect access to benefits tied to citizenship such as Social Security and Medicaid.
The century-old Supreme Court precedent at the center of the fight is Wong Kim Ark, which first clarified how the Citizenship Clause applied to children born in the United States to foreign parents. In that decision the court wrote, “A child born in the United States, of parents of Chinese descent, who, at the time of his birth, are subjects of the Emperor of China, but have a permanent domicil and residence in the United States… becomes at the time of his birth a citizen of the United States, by virtue of the first clause of the Fourteenth Amendment of the Constitution.”
Justices probed how an order like this would work in practice, raising practical concerns about hospitals and states handling birth certificates. “On the day after it goes into effect — it’s just a very practical question of how it’s going to work,” asked Justice Brett Kavanaugh. “What do hospitals do with a newborn? What do states do with a newborn?”
Other justices warned about consequences for children, with Justice Sonia Sotomayor saying the government’s position “makes no sense whatsoever” and worrying it could leave some kids “stateless.” “So as far as I see it, this order violates four Supreme Court precedents,” added Sotomayor during earlier arguments, underscoring the legal stakes at play.
Critics fear chaotic, uneven enforcement across states and families, and legal experts warn of a patchwork where some children would be treated differently from others. Amanda Frost, director of the Immigration, Migration and Human Rights Program at the University of Virginia School of Law, warned of immediate harms, saying, “Denied all the benefits and privileges of citizenship and theoretically deportable on day one of their life. And then every single American family having a child will now have to prove their status before that child is considered a citizen by the U.S. government.”
Supporters counter that the order targets specific abuses like birth tourism and restored clarity would strengthen borders and protect taxpayers. Figures such as Peter Schweizer have described a commercialized “birth tourism” market that, they say, exploits loose interpretations of birthright citizenship and merits a robust legal response.
The case captioned as Trump v. Barbara (25-365) names a Honduran plaintiff who joined the suit while pregnant, and the high court is expected to issue a ruling within months. Whatever the outcome, the decision will reshape how the nation defines membership, who receives federal benefits, and how immigration policy is enforced across the country.
