Donald Trump loses landmark birthright citizenship case in 6 to 3 Supreme Court ruling

The United States Supreme Court has upheld birthright citizenship for children born on American soil to parents who are unlawfully or temporarily present in the country, rejecting one of President Donald Trump’s most consequential attempts to reshape United States immigration policy.

In a 6 to 3 ruling issued on Tuesday, June 30, 2026, the Supreme Court affirmed a lower court order blocking Executive Order 14160. The presidential directive would have denied automatic citizenship to specified children unless at least one parent was a United States citizen or lawful permanent resident at the time of birth.

Five justices held that the Fourteenth Amendment itself protects the citizenship of children born in the United States regardless of whether their parents are undocumented immigrants, temporary visa holders or other non-permanent residents. Justice Brett Kavanaugh supplied the sixth vote against the executive order on the narrower ground that it violated the Immigration and Nationality Act.

The ruling immediately preserves the citizenship status of children who could have been affected by Donald Trump’s order and prevents federal agencies from implementing a system that would have required many parents to prove their own citizenship or immigration status before obtaining citizenship documents for newborn children. Experts had estimated that the order could directly affect as many as 250,000 births each year.

What did Donald Trump’s birthright citizenship executive order attempt to change?

Donald Trump signed Executive Order 14160 on January 20, 2025, the first day of his second presidential term. The order directed federal departments and agencies not to recognise automatic United States citizenship for two categories of children born after the directive took effect.

The first category covered children whose mothers were unlawfully present in the United States when they gave birth and whose fathers were neither United States citizens nor lawful permanent residents. The second covered children whose mothers were lawfully but temporarily present on arrangements such as student, work, tourist or visa waiver status, again where the father was not a citizen or permanent resident.

The administration argued that the Fourteenth Amendment’s phrase requiring a person to be subject to United States jurisdiction excluded children whose parents lacked permanent allegiance to the country. Under that interpretation, physical birth inside the United States would not be sufficient when neither parent had citizenship or permanent residence.

The executive order would have required federal agencies to stop issuing or recognising citizenship documents for affected children. The practical consequences could have extended to passports, Social Security numbers, access to some public programmes and the ability to prove lawful status throughout a person’s life.

The Supreme Court rejected that parental-status test. The court held that children born in the United States to parents who are unlawfully or temporarily present are subject to United States law and jurisdiction and consequently become citizens at birth.

Why did five justices conclude that the Fourteenth Amendment protects these children?

Chief Justice John Roberts wrote the controlling opinion, joined by Justices Sonia Sotomayor, Elena Kagan, Amy Coney Barrett and Ketanji Brown Jackson. The five-justice majority examined the language of the Citizenship Clause, its historical background and the legal tradition surrounding citizenship at birth.

The Citizenship Clause states that all persons born or naturalised in the United States and subject to its jurisdiction are citizens of the United States and of the state in which they reside. The majority found that temporary presence, unlawful presence and parental domicile do not appear among the constitutional text’s citizenship conditions.

The majority concluded that a child born inside the country is generally subject to United States jurisdiction because American law applies to that child and the child’s parents. The recognised exceptions are narrow and historically concern situations in which the United States does not exercise ordinary legal authority, such as children born to accredited foreign diplomats or enemy forces occupying American territory.

John Roberts rejected the administration’s argument that parental domicile or permanent allegiance must be added to the constitutional test. The opinion found little evidence that the Fourteenth Amendment’s authors intended to make a newborn child’s citizenship depend on the lawful or permanent residence of the parents.

The court also noted that the language repeatedly used in Donald Trump’s order, including references to mothers, fathers, lawful presence and temporary presence, is absent from the Citizenship Clause. The majority concluded that introducing those conditions through executive action would rewrite rather than interpret the constitutional provision.

How did the 1898 Wong Kim Ark ruling shape the Supreme Court’s decision?

The Supreme Court relied heavily on United States v. Wong Kim Ark, the 1898 decision that recognised the citizenship of a man born in San Francisco to Chinese parents who were barred from naturalising under the discriminatory laws then in force.

The federal government argued that Wong Kim Ark was narrower because the parents in that case were permanently domiciled in the United States. Donald Trump’s administration maintained that the decision did not resolve the status of children whose parents were undocumented or temporarily present.

The majority rejected that attempt to limit the precedent. John Roberts concluded that Wong Kim Ark’s reasoning established a general territorial rule under which birth in the United States confers citizenship, subject only to narrow historical exceptions.

The ruling also connected birthright citizenship with the history of the Fourteenth Amendment. The amendment was ratified in 1868 after the Civil War and repudiated the Supreme Court’s 1857 Dred Scott v. Sandford decision, which had denied federal citizenship to people of African descent.

The majority treated the Citizenship Clause as an effort to create a clear national citizenship rule that could not be changed through ordinary political preferences or administrative decisions. Making citizenship depend on a later examination of parental domicile would introduce uncertainty into a provision designed to settle citizenship at birth.

The court’s reasoning means Wong Kim Ark remains a broad constitutional precedent rather than a ruling limited to children of lawfully domiciled immigrants. That interpretation significantly restricts the ability of future presidents to narrow birthright citizenship through executive action.

Why was the ruling described as 6 to 3 when only five justices joined the constitutional opinion?

The result against Donald Trump’s executive order was 6 to 3, but the justices did not all agree on why the order was unlawful.

John Roberts and four other justices concluded that the order violated the Fourteenth Amendment. That five-justice constitutional majority creates the controlling rule that the amendment protects children born in the United States to undocumented and temporarily present parents.

Brett Kavanaugh agreed that the order could not be enforced but would have decided the case under federal legislation rather than the Constitution. Brett Kavanaugh found that Section 1401 of Title 8 already provides citizenship at birth using language modelled on the Fourteenth Amendment and that Congress had not authorised the new exceptions created by Donald Trump.

Brett Kavanaugh maintained that Congress could amend the law to create exclusions for children of undocumented or temporarily present parents. That position did not command a majority and does not displace the five-justice holding that the Constitution itself prohibits the broad exclusions contained in the executive order.

Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented. The dissenting opinions argued in different forms that birthright citizenship historically depended on complete allegiance or parental domicile and that the Wong Kim Ark precedent did not necessarily protect every child born to temporary visitors or undocumented immigrants.

The ideological alignment was notable. Amy Coney Barrett, appointed by Donald Trump, joined the constitutional majority, while Brett Kavanaugh, another Donald Trump appointee, voted to block the executive order on statutory grounds.

Can Donald Trump and Congress still restrict birthright citizenship through legislation?

Donald Trump responded by urging Congress to legislate new limits and argued that a constitutional amendment would not be necessary. The Supreme Court’s divided reasoning makes that path considerably more difficult than the presidential response suggested.

Brett Kavanaugh’s separate opinion accepted that Congress could amend federal law and create new exceptions. However, the five-justice majority concluded that the Fourteenth Amendment already guarantees citizenship to the children covered by Donald Trump’s order.

An ordinary federal statute denying citizenship to those same children would consequently face the majority’s constitutional barrier. Congress cannot override the Constitution through normal legislation, and a law closely reproducing the executive order would almost certainly generate another immediate court challenge.

Congress could attempt narrower legislation addressing documentation, fraud or particular circumstances at the edges of the citizenship rule. It could not confidently abolish broad territorial birthright citizenship while the June 30 constitutional holding remains controlling precedent.

A constitutional amendment would provide the clearest legal route for changing the Citizenship Clause itself, but the amendment process requires approval by two-thirds of both houses of Congress and ratification by three-quarters of the states. That threshold makes a fundamental citizenship change politically difficult.

The ruling therefore does more than invalidate one executive order. It limits the ability of both future presidents and ordinary congressional majorities to remove birthright citizenship from the children of undocumented immigrants and temporary visa holders.

What practical consequences would Donald Trump’s order have created for families and states?

The executive order would have required government institutions to determine parental immigration status at or shortly after a child’s birth. Hospitals, state vital-records offices, passport authorities and the Social Security Administration could have faced new demands for immigration evidence.

Families in which neither parent was a citizen or lawful permanent resident could have been required to produce passports, visas, immigration files or other records before their children received federal recognition as citizens. The system could also have affected families with complicated documentation, pending asylum applications or uncertainty over a parent’s status.

The legal status of affected children would have shaped access to passports, employment, voting upon adulthood and protection against deportation. Children denied citizenship could potentially have inherited their parents’ nationality, but nationality laws differ widely, creating a risk that some children would face uncertain or stateless status.

States could also have developed inconsistent procedures for recording births and determining eligibility for documents or programmes. A child might have possessed a state birth certificate while lacking federal recognition as a citizen, creating long-term disputes over identity and legal rights.

The nationwide class-action order upheld by the Supreme Court prevented those administrative systems from taking effect. The ruling gives federal and state institutions a uniform rule under which nearly every person born on United States territory is recognised as a citizen from birth.

How does the ruling relate to the Supreme Court’s earlier decision on nationwide injunctions?

The birthright citizenship dispute had already reached the Supreme Court in 2025 through a procedural case concerning nationwide injunctions. The court then restricted the ability of individual federal judges to block government policies for people who were not parties to a lawsuit.

That 2025 decision did not determine whether Donald Trump’s citizenship order was constitutional. It left opponents searching for other procedural mechanisms capable of protecting all potentially affected children.

A federal judge in New Hampshire subsequently provisionally certified a nationwide class consisting of children who would be denied citizenship under the executive order. The judge then blocked enforcement for that class, allowing the legal challenge to produce national protection without relying solely on a universal injunction.

The Supreme Court’s June 30 ruling affirmed that judgment. The decision therefore demonstrates that class actions can remain a route to nationwide relief when a government policy affects a clearly defined group in the same way.

The procedural history will influence future litigation against federal policies. Advocacy organisations and state governments may place greater emphasis on class certification after the Supreme Court’s restrictions on nationwide injunctions.

The final ruling also resolves the substantive citizenship issue that the 2025 case deliberately left unanswered. Donald Trump’s order is now blocked because the country’s highest court has rejected its legal foundation, not merely because of disagreement over the geographic reach of a lower court’s injunction.

What does the birthright citizenship defeat mean for Donald Trump’s immigration agenda?

The judgment represents a major limit on Donald Trump’s use of presidential authority to reshape immigration policy without congressional legislation or a constitutional amendment.

The Supreme Court has supported parts of Donald Trump’s second-term immigration programme, including decisions affecting asylum processing and humanitarian protections. The birthright citizenship ruling shows that the court’s conservative majority is not prepared to approve every executive action simply because it concerns immigration or national sovereignty.

The administration can continue enforcing immigration laws against undocumented parents. The ruling does not provide parents with legal status, prevent deportation or create a right for a citizen child’s family to remain in the United States.

It does establish that a child’s citizenship cannot be withdrawn because of the parents’ immigration category at the time of birth. A United States-born child remains a citizen even when one or both parents are later removed from the country.

Donald Trump can pursue legislation, additional immigration enforcement and policies aimed at what the administration describes as birth tourism. The administration cannot revive Executive Order 14160 in substantially the same form without confronting the Supreme Court’s constitutional ruling.

The decision consequently preserves a distinction that has long shaped United States immigration law. The government may control the admission, detention and removal of non-citizens, but the Constitution determines the citizenship of children born within the country.

What are the key takeaways from the United States Supreme Court birthright citizenship ruling?

• The United States Supreme Court ruled 6 to 3 on June 30, 2026, that Donald Trump’s executive order restricting birthright citizenship could not be enforced against children born to undocumented or temporarily present parents.
• Five justices held that the Fourteenth Amendment itself protects the citizenship of children born on United States soil, creating a binding constitutional rule that ordinary legislation cannot simply override.
• Justice Brett Kavanaugh supplied the sixth vote against the order on narrower statutory grounds, concluding that existing federal law grants birthright citizenship and that Congress had not authorised Donald Trump’s proposed exceptions.
• Executive Order 14160 targeted children whose mothers were undocumented or temporarily present when the fathers were neither United States citizens nor lawful permanent residents at the time of birth.
• The Supreme Court relied on the 1898 United States v. Wong Kim Ark precedent and rejected the argument that citizenship depends on a parent’s lawful domicile, permanent residence or political allegiance.
• The ruling preserves citizenship for potentially hundreds of thousands of children born each year and prevents federal agencies from introducing parental immigration checks before recognising newborn children as citizens.
• Donald Trump urged Congress to legislate new restrictions, but the five-justice constitutional holding means any broad law reproducing the executive order would face a serious and probably decisive Fourteenth Amendment challenge.
• The judgment does not protect undocumented parents from deportation or grant them legal status, but it confirms that their United States-born children remain citizens regardless of the parents’ immigration position.
