The Future of Birthright Citizenship: Trump v. Barbara and the 14th Amendment

For over a century, a simple principle determined who counts as a U.S. citizen: If you were born on U.S. soil, you are an American (subject to a very narrow set of exceptions). This is known as birthright citizenship, and it touches millions of families.

The U.S. Supreme Court upheld birthright citizenship against legal challenges in its June 2026 ruling in Trump v. Barbara. The case struck down a 2025 executive order that sought to bypass the long-settled rule on birthright citizenship by restricting eligibility based on parental immigration status.

This article discusses the legal basis for birthright citizenship, as confirmed by the U.S. Supreme Court, and what it means for those living in America. If you need legal regarding whether you or your child can receive U.S. citizenship, consult an experienced immigration attorney.

Where Birthright Citizenship Comes From

Birthright citizenship is guaranteed by the U.S. Constitution. The first sentence of the 14th Amendment, the Citizenship Clause, 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.”

The Citizenship Clause provides two pathways for citizenship:

1. Being born in the United States
2. Being naturalized (a legal process for immigrants)

The 14th Amendment was enacted following the Civil War and was intended to reverse the Dred Scott v. Sandford (1857) decision. This decision’s infamous ruling declared that Black people could not be citizens of the United States, regardless of whether they were enslaved or free.

Members of Congress passed a statute codifying birthright citizenship for all babies born in the United States. All babies born on U.S. soil are birthright citizens, subject to limited exceptions.

What the Citizenship Clause Means for People in the US

The U.S. Supreme Court has interpreted the Citizenship Clause to mean that nearly all children born in the United States are U.S. citizens, regardless of whether their parents were citizens or have legal immigration status.

The Legal Challenge To Birthright Citizenship

Birthright citizenship has come under political attack in recent years. Most recently, President Trump has long maintained that the U.S. Constitution does not guarantee birthright citizenship for babies born on U.S. soil.

2025 Executive Order Challenging Birthright Citizenship

On the first day of his second term in 2025, President Trump signed Executive Order 14160, Protecting the Meaning and Value of American Citizenship. It barred citizenship for children born in the United States if their parents entered the country illegally or are working legally in the U.S. on temporary visas.

The executive order sought to interpret “subject to the jurisdiction thereof” in the Citizenship Clause to limit who qualifies as a U.S. citizen from birth. It outlined two categories of people that it says are not “subject to the jurisdiction” of the United States:

1. A child whose mother was not lawfully present in the United States, and whose father was not a U.S. citizen (or lawful permanent resident) at the moment the child was born
2. A child whose mother was lawfully but temporarily in the United States, and whose father was not a U.S. citizen or lawful permanent resident, when the child was born

The executive order directed the U.S. Secretary of State, the Attorney General, and the Commissioner of Social Security to ensure that their policies are consistent with the order.

Legal Challenge to Trump’s Birthright Citizenship Executive Order: Trump v. Barbara

In response to the executive order, immigrant rights groups and almost half of the U.S. states challenged it through a case called Trump v. Barbara.

U.S. district courts hearing the case ruled that Executive Order 14160 was unconstitutional, and three U.S. Courts of Appeals refused to lift the block on those orders during the appeals process. The U.S. Supreme Court granted certiorari and ultimately ruled that the executive order is unconstitutional.

The Supreme Court’s Ruling in Trump v. Barbara

On April 1, 2026, the U.S. Supreme Court heard oral arguments in Trump v. Barbara. On June 30, 2026, the Court ruled 6-3 that Executive Order 14160 is unconstitutional and violates the Fourteenth Amendment. The Court upheld the century-old understanding that anyone born on U.S. soil is automatically a citizen.

Why Wong Kim Ark Matters in the Trump v. Barbara Case

Both parties argued to the U.S. Supreme Court that one of its prior cases on the Citizenship Clause, United States v. Wong Kim Ark (1898), supported their arguments and that the Court should follow that precedent and rule in their favor.

Wong Kim Ark is about the citizenship of a man born in the United States to parents who had emigrated from China. His parents lived in San Francisco for more than twenty years, during which time Wong Kim Ark was born.

His parents were lawfully residing in the United States but were ineligible to naturalize under existing law. In 1890, his parents returned to China. Several years later, Wong Kim visited his parents in China and then returned to the United States. Upon his return, he was barred from entering the country.

Wong Kim Ark argued that he was a birthright citizen because he was born on U.S. soil, even though his parents were not citizens. The U.S. Supreme Court agreed. The Court ruled that the Citizenship Clause meant that Wong Kim Ark was a birthright citizen, even though his parents were not citizens and were ineligible to become citizens at the time of his birth.

This has been a stable rule. A child born on U.S. soil is an American citizen, subject to narrow exceptions, such as the children of foreign diplomats, who are not fully “subject to the jurisdiction” of the United States.

Main Arguments in Trump v. Barbara

The U.S. Supreme Court Justices considered two competing views of the same constitutional text. Here is a look at each side’s arguments, which are also supported by amicus briefs from groups that have an interest in the case.

The Case for Limiting Birthright Citizenship

Those defending the executive order (the Petitioners) argued the following:

• “Subject to the jurisdiction” has a narrower meaning. They contend the phrase requires more than simply being born on U.S. soil. They argue that the Clause was meant to exclude people who owe allegiance to another country. These arguments rely on domicile having a subjective-intent element — a person’s intent to remain in the United States.
• The framers of the U.S. Constitution and Amendments had specific intent. They argue that the amendment was written primarily to secure citizenship for freed slaves. They do not believe that the Fourteenth Amendment protects every child born to people without lawful status, i.e., illegal aliens.
• The executive can clarify the rule. They assert that the executive order provides a permissible interpretation rather than rewriting the Constitution.

The Petitioners agreed that the ruling in Wong Kim Ark would govern the case. The Solicitor General requested a constitutional ruling from the Court.

The Case for Protecting Birthright Citizenship

Those challenging the order, the Respondents (the plaintiffs in the lawsuit), argued the following:

• The text is broad and clear. Nearly everyone born in the United States is “subject to the jurisdiction” of its laws, since they must obey those laws and be prosecuted under them.
• Precedent strongly supports their position. Wong Kim Ark and more than a century of practice confirm that parental immigration status, whether that be noncitizens, undocumented immigrants, or otherwise, does not change a child’s birthright citizenship.
• Only a constitutional amendment could change the rule. The Respondents argue that an executive order cannot override the plain meaning of the Fourteenth Amendment.

The Respondents asked the court to reaffirm its decision in United States v. Wong Kim Ark. The Court ultimately sided with the Respondents in striking down the order.

Native American Birthright Citizenship

The question of Native American birthright has a distinct constitutional history. In Elk v. Wilkins (1884), the Supreme Court held that enrolled members of Indian Tribes were not automatically citizens at birth.

The Court based its decision on the fact that, at the time, Native Americans were understood to owe allegiance to tribal sovereigns. It was believed that they were not subject to U.S. political jurisdiction under the Citizenship Clause. Congress later changed the rule, making Native Americans born in the United States citizens, regardless of tribal enrollment.

In Trump v. Barbara, the Petitioners cite Elk. They argue that the Citizenship Clause has limits tied to “direct and immediate allegiance.” On the other hand, the Respondents argue that Elk reflects only a narrow, historically closed set of exceptions rather than a broad power to restrict citizenship more generally.

Get Help Understanding Your Rights Under Immigration Law

Birthright citizenship rests on the Fourteenth Amendment’s promise that American citizenship is given to all people born on U.S. soil and subject to its laws. For more than a century, most U.S.-born children have had a clear path to U.S. citizenship. In Trump v. Barbara, the U.S. Supreme Court upheld this long-established understanding of birthright citizenship.
