Subject to the Jurisdiction

What the executive order tried to do.

Executive Order 14160, "Protecting the Meaning and Value of American Citizenship," was signed on January 20, 2025. It directed every federal agency to stop issuing or recognizing proof of citizenship, passports, Social Security numbers, and the rest, for a baby born in the United States in two situations: when the mother was in the country unlawfully, or when she was here only temporarily, on a student, work, or tourist visa, and in either case the father was not a citizen or green-card holder.

It was set to apply to children born about 30 days later, on or after February 19, 2025. By one widely cited estimate, it would have denied citizenship to roughly 150,000 to 250,000 babies every year. The order did not change a single law passed by Congress. It reinterpreted six words in the Constitution, and it was blocked by federal judges within days. It never took effect anywhere.

What it was meant to accomplish.

The order was sold as closing a loophole. Birthright citizenship, the argument goes, is a "magnet" for illegal immigration: come to the United States, have a child who is automatically a citizen, and that "anchor baby" lets the family put down roots and stay. The order folded two different things into that one idea, the "anchor babies" of undocumented parents and "birth tourism" by visitors on temporary visas.

Trump has made the case the same way for a decade, and it tends to fall apart on inspection. Here is how he put it when he first promised to end it by executive order:

Two things in that one sentence are wrong. Citizenship is not a temporary "85-year" benefit; it is for life. And the United States is far from the "only country" that grants it: roughly 30 to 35 nations do, including Canada and Mexico and most of the Americas. Fact-checkers have rated the "only country" claim false for years. The premise behind the order was shaky before the order was even written.

The anchor-baby version is mostly a myth, too, because of how immigration law actually works.

• A citizen child cannot sponsor a parent for a green card until the child turns 21. A newborn does nothing for two decades.
• Even at 21, a parent who entered illegally usually has to leave the country to apply, which triggers a 3- or 10-year bar on returning. The hardship waiver that can excuse it counts hardship to a citizen spouse or parent, not to a child.
• A citizen child is no shield from deportation. Parents of citizen children are removed routinely; in this administration's first months, at least 11,000 citizen children had a parent detained.
• And people do not migrate to have citizen babies. The research is consistent that they come for work, family, and safety.

So a child born here gives undocumented parents essentially no usable immigration benefit for at least 21 years, and often not even then. The "anchor" mostly is not one.

Birth tourism, the order's other target, is real, but small and separate: foreigners on tourist visas who come to give birth, not undocumented residents having children. The estimates are shaky and range from a few thousand to a few tens of thousands a year, against roughly 3.6 million U.S. births. A genuine if minor thing, and a different one than the "anchor baby" rhetoric implied.

And here is what undercuts the order on its own terms: because migration is driven by work and safety, not by a baby's passport, ending birthright citizenship would not have reduced illegal immigration. By the best projections it would have done the reverse, manufacturing a large and growing population of U.S.-born people with no status.

The clause the order collided with.

Birthright citizenship is not a statute or a policy. It is written into the Constitution, in the first sentence of the 14th Amendment.

It was written for a specific reason. In 1857, in Dred Scott, the Supreme Court had ruled that Black people could never be citizens. The 14th Amendment was passed after the Civil War to erase that ruling and to guarantee, in the Constitution itself, that citizenship belongs to everyone born here, no matter their ancestry or their parents' status.

The meaning of those words was settled in 1898. In United States v. Wong Kim Ark, the Court held that a man born in San Francisco to Chinese immigrant parents, people who by law could never become citizens themselves, was a citizen from birth. For more than 125 years, "subject to the jurisdiction" has been understood to exclude only a few narrow categories: the children of foreign diplomats, the children of an invading army, and, historically, some Native Americans on tribal land. Not the children of ordinary immigrants.

The case turned on six words.

The administration's theory rested entirely on the phrase "and subject to the jurisdiction thereof." It argued the words mean more than simply being subject to American law while on American soil. They require, on this reading, full political allegiance to the United States, which the children of people here illegally or temporarily do not have, because their parents still owe allegiance to another country. For support it reached back to an 1866 Senate debate, where the clause's sponsor said it would not cover "foreigners, aliens," and it argued that Wong Kim Ark applied only to the children of immigrants here lawfully and permanently.

This is a real constitutional argument, made for years by a small group of originalist scholars. But it has always been the minority view, and it is rejected even by prominent conservatives.

How the Court ruled, 6 to 3.

Chief Justice John Roberts wrote the majority opinion, joined by Justices Sotomayor, Kagan, Barrett, and Jackson. The Court held that children born in the United States to parents who are here unlawfully or temporarily are "subject to the jurisdiction" of the country and are citizens at birth, exactly as the 14th Amendment says. Roberts called citizenship "the right to have rights," and wrote that the Amendment "extended that promise to 'every free-born person in this land.'"

This is where "narrowly" comes in, and it is worth being precise. The vote against the order was 6 to 3, not close. But only five justices reached the constitutional holding. The sixth, Justice Kavanaugh, agreed the order had to fall but wrote that the Court "could have (and in my respectful view, should have) decided the case on that narrow ground" of federal statute, without ruling on the Constitution at all. So the order lost decisively, while the constitutional rule that a birth here makes a citizen rested on a one-vote margin.

In dissent, Justice Thomas wrote that the Court had "repurposed the Fourteenth Amendment." Justice Alito warned that the ruling "confers citizenship on virtually everyone who happens to be born in this country, including the children of 'birth tourists.'" Notably, two of the three justices Trump appointed in his first term, Barrett and Kavanaugh, agreed the order could not stand.

How it got here: four federal judges blocked the order in early 2025. In June 2025, in Trump v. CASA, the Court limited the power of judges to issue nationwide injunctions, but pointedly did not decide whether the order itself was legal. A nationwide class action by affected families kept it frozen, and the Court finally took up the merits, deciding them today.

The country the order would have built.

This was not a narrow administrative fix. Ending birthright citizenship would have created, year after year, a population of people born in the United States who belong to no country at all.

The order would have denied citizenship to roughly 255,000 babies a year. That is a city the size of Buffalo or St. Louis, born every year and locked out of the country of their birth. Over a decade it is about 2.5 million people, another Chicago, all of them American by birth and foreign by decree.

For each of those children it would mean being born in an American hospital with no Social Security number, no passport, and no legal right to work or to vote, undocumented from the first day of life in the only country they will ever know. Some would be stateless, claimed by no nation on earth.

That is the world the 14th Amendment was written to close: the world of Dred Scott, where citizenship could be withheld by ancestry no matter where a person was born. The Amendment made being born on American soil enough, precisely so citizenship could never again be denied down a bloodline. The order would have begun to rebuild what the Amendment tore down.
