On June 30, 2026, the Supreme Court issued its decision in Trump v. Barbara, blocking the federal government from implementing President Trump’s executive order restricting birthright citizenship. The Court affirmed a nationwide preliminary injunction, meaning that the executive order could not take effect anywhere in the country while the case was in process. Five Justices concluded that the executive order violated the Citizenship Clause of the Fourteenth Amendment. A sixth Justice, Justice Brett Kavanaugh, agreed that the order could not be enforced because it conflicted with existing federal law. The decision is a significant development in the legal battle over birthright citizenship, one of the country’s longest-standing constitutional protections.
What Did the Executive Order Attempt to Do?
The case, Trump v. Barbara, concerned an executive order issued by President Trump directing federal agencies not to recognize certain children born in the United States as US citizens. The order covered two categories of children:
The first category included children whose mothers were unlawfully present in the United States at the time of birth and whose fathers were neither US citizens nor lawful permanent residents, commonly known as green card holders.
The second category included children whose mothers were lawfully but temporarily present in the United States and whose fathers were neither US citizens nor lawful permanent residents. This category included mothers in the United States through the Visa Waiver Program or in temporary student, work, or tourist status.
The order did not apply simply because one or both parents were undocumented or held temporary immigration status. Whether it applied depended on the mother’s immigration status and whether the father was a US citizen or green card holder. The Trump administration argued that children born under these circumstances were not automatically entitled to citizenship under the Constitution.
Why Did the Supreme Court Reject the Order?
The case centered on the Citizenship Clause of the Fourteenth Amendment, which states that anyone born or naturalized in the United States and "subject to the jurisdiction" of the United States is a US citizen. The Trump administration argued that children born to undocumented immigrants or certain temporary visa holders are not fully "subject to the jurisdiction" of the United States and therefore should not automatically receive citizenship.
Five Justices, the majority, disagreed. The justices explained that being "subject to the jurisdiction" of the United States generally means being required to follow US laws and subject to the authority of US courts and government. Because virtually everyone living in the United States, including undocumented immigrants and temporary visitors, is subject to US law, their children born in the country are also covered by the Constitution's guarantee of birthright citizenship.
The Court also pointed to the long-established legal principle of jus soli, a Latin phrase meaning "right of the soil." Under this principle, citizenship is determined by where a person is born rather than by the immigration status or nationality of their parents.
The justices rejected the argument that parents must be US citizens, lawful permanent residents, or otherwise permanently settled in the country before their US-born children can become citizens. Instead, the Court explained that birthright citizenship has only a few narrow exceptions that have been recognized for more than a century, such as children born to accredited foreign diplomats or children born in areas under the control of a hostile occupying military force.
Finally, the Court also relied on more than a century of legal precedent, including the landmark 1898 decision in United States v. Wong Kim Ark. In that case, the Supreme Court held that a child born in the United States to noncitizen parents who lived permanently in the country was a US citizen. In Barbara, the majority concluded that the same constitutional reasoning applies when a child’s parents are temporarily or unlawfully present in the United States.
What Does the Decision Mean in Practice?
The decision means that children born in the United States will continue to receive US citizenship at birth, regardless of their parents’ immigration status in most circumstances. The narrow historical exceptions remain in place, including the exception for children born to accredited foreign diplomats. The nationwide preliminary injunction against the Executive Order also remains in effect. As a result, federal agencies cannot implement Executive Order No. 14160 anywhere in the United States while the injunction remains in place. Children who would have been affected by the order must continue to be recognized as US citizens at birth.
Birthright citizenship has been a defining feature of American law for generations. Supporters argue that it reflects the country’s history as a nation shaped by immigration and creates a clear and consistent rule for determining citizenship. Opponents argue that the rule encourages unauthorized immigration and should be reconsidered. Those broader policy disagreements were not the central issue before the Court. The legal question was whether the president could, through an executive order, exclude certain US-born children from citizenship despite the Fourteenth Amendment, existing federal law, and longstanding Supreme Court precedent.
The Supreme Court’s decision resolves the immediate challenge and establishes, under current law, that the executive branch cannot deny citizenship at birth to the children covered by the executive order. Congress may consider legislation addressing birthright citizenship, particularly in light of Justice Kavanaugh’s concurring opinion. However, legislation creating the same restrictions would face a significant constitutional challenge because five Justices concluded that those restrictions are inconsistent with the Fourteenth Amendment. For now, the Court’s ruling preserves the longstanding rule that a person born in the United States is generally a US citizen from birth.
