Birthright citizenship remains in effect in the United States while the Supreme Court considers a case that could decide whether President Donald Trump can restrict automatic citizenship for some children born on U.S. soil.
The case, Trump v. Barbara, centers on an executive order Trump signed on January 20, 2025. The order seeks to deny U.S. citizenship documents to children born in the United States when their mother was unlawfully present and their father was neither a U.S. citizen nor a lawful permanent resident. It would also apply when the mother was in the country lawfully but temporarily, such as on a student, work or tourist visa, and the father was neither a citizen nor a lawful permanent resident.
The Supreme Court heard oral arguments on April 1, 2026, according to the court audio page. A final decision is expected by the end of the current term, making birthright citizenship one of the biggest immigration and constitutional cases before the court.
The question has drawn new attention after The Atlantic examined what could happen if the court changes how the 14th Amendment is applied, while CBS News explained how the current rule works and why the Trump order is being challenged.
What Trump Order Would Change?
The executive order is not written to strip citizenship from everyone born in the United States. It targets children born after the order takes effect who fall into two categories.
- Children whose mother was unlawfully present in the United States at the time of birth, when the father was not a U.S. citizen or lawful permanent resident.
- Children whose mother was lawfully but temporarily present in the United States, such as under a student, work or tourist visa, when the father was not a U.S. citizen or lawful permanent resident.
Under the order, federal agencies would not issue documents recognizing U.S. citizenship to those children. That would affect passports, citizenship recognition and other federal records tied to birth status.
The order says the policy would apply prospectively. In ordinary terms, the fight is mainly about babies born after implementation, rather than people already treated as citizens for years.
Could Birthright Citizenship Change Right Away?
No immediate change has taken effect nationwide as of June 22, 2026. Lower courts blocked the policy after lawsuits from states, civil rights groups and immigrant-rights organizations.
The Supreme Court already handled one related issue in 2025, when it limited the ability of lower courts to issue universal injunctions. That ruling did not decide whether the executive order is constitutional. It dealt with how broad court orders can be when judges block federal policy.
The current case puts the core question before the justices: whether the order is allowed under the Citizenship Clause and federal citizenship law.
Who Would Be Most Affected?

The people most directly affected would be newborns in the United States whose parents do not include a U.S. citizen or lawful permanent resident, and where the mother is either unlawfully present or temporarily present.
That could include children born to undocumented parents. It could also include children born to parents in the United States on temporary visas, including students, workers, tourists and some other temporary categories.
The change would create practical problems very quickly. Hospitals, state vital-record offices, passport agencies and families would need to determine parental immigration status at birth. Parents could face delays or denials when trying to obtain documents for a child. Schools, health programs and other systems would then face questions about status that current practice avoids.
For demographic context, we covered how immigration shapes long-term U.S. labor and population trends in our report on how immigration shapes the U.S. workforce. A change to birthright citizenship would sit inside that larger debate over population growth, legal status and future labor supply.
Why The Supreme Court Case Is So Big?
The case is big because it reaches the first sentence of the 14th Amendment. That amendment was adopted after the Civil War and overturned the logic of Dred Scott v. Sandford, the 1857 decision that said Black Americans could not be citizens.
The Atlantic noted that the case asks a basic question about who gets to be American. CBS News described the issue as a direct challenge to the long-standing understanding that people born on American soil are citizens at birth regardless of parental immigration status.
The National Constitution Center said the April 2026 arguments focused on who the 14th Amendment Citizenship Clause covers, how to read the 1898 Wong Kim Ark precedent and whether the government has authority to narrow birthright citizenship by executive order.
What Supporters Of The Trump Order Argue?

Supporters of the order say the phrase “subject to the jurisdiction thereof” should exclude children whose parents are in the country unlawfully or only temporarily. They argue that mere birth on U.S. soil should not automatically settle citizenship when the parents lack permanent legal ties to the United States.
The White House order says the 14th Amendment has never been interpreted to extend citizenship universally to every person born in the country. It also says Congress has tied citizenship at birth to being born in the United States and subject to U.S. jurisdiction.
The administration position asks the court to accept a narrower reading of the Citizenship Clause than the one used by federal agencies for generations.
What Opponents Of The Order Argue?
Opponents say the order violates the plain language of the 14th Amendment, the 1898 Supreme Court precedent and federal citizenship law. They argue that the main exceptions historically involved children of foreign diplomats, not children of immigrants living under U.S. law and subject to U.S. courts.
The Brennan Center for Justice says the order is an attempt to end the 14th Amendment guarantee of birthright citizenship and notes that state attorneys general, civil rights groups and immigrant-rights groups quickly filed lawsuits.
Opponents also warn about practical fallout. A child born in the United States could be denied federal citizenship documents, while still having no clear citizenship elsewhere. That could create legal uncertainty for families, schools, health programs and state agencies.
What Happens If The Court Upholds The Order?
If the Supreme Court upholds the order, federal agencies could begin applying new citizenship rules to the affected categories of children born after the effective date. The administration would likely issue guidance to agencies that handle passports, immigration records and other citizenship documents.
States would then face pressure over birth certificates, public benefits and proof of status. A U.S. birth certificate shows birth in the country, but the federal government would no longer treat that fact alone as enough for citizenship in the affected cases.
More lawsuits would likely follow over implementation, documentation, retroactivity, state responsibilities and the rights of children whose status is disputed.
What Happens If The Court Rejects The Order?
If the court rejects the order, the current understanding of birthright citizenship would remain in place. Children born in the United States would continue to be treated as citizens at birth, with the narrow historical exceptions that already exist.
A ruling against the administration could also limit future attempts by presidents to change citizenship rules by executive order. Congress would still debate immigration and citizenship policy, but the 14th Amendment would remain the barrier against ending citizenship by birth for the covered groups.
Birthright citizenship is separate from naturalization, but the two debates now appear in the same political moment. Naturalization is the process through which immigrants become citizens after meeting legal requirements. Birthright citizenship covers people who become citizens because they are born in the United States.
Our team at NCHStats recently covered the administration focus on citizenship enforcement in our report on the denaturalization push under the Trump DOJ. That issue applies to naturalized citizens accused of fraud or serious legal problems in the naturalization process. Birthright citizenship is different because it concerns citizenship from birth.
The two debates still point to the same larger question: how far the federal government can go in narrowing who counts as an American citizen.
Why The Decision Could Affect Population And Immigration Data
A change in birthright citizenship would also affect how the country measures population, immigration and legal status. The United States has already seen major shifts in population growth tied to births, deaths and migration.
We tracked those changes in our report on U.S. population by state and city, as well as our coverage of unauthorized immigration and U.S. border crossing data. If citizenship at birth changes for some U.S.-born children, future population categories could become more complicated for agencies, schools and local governments.
Bottom Line
Birthright citizenship has not changed as of June 22, 2026. Children born in the United States are still treated as citizens at birth under the long-standing interpretation of the 14th Amendment.
The Supreme Court case could change that for children born to certain noncitizen parents if the justices uphold the Trump executive order. A ruling against the order would keep the current rule in place and reaffirm the broad understanding of citizenship at birth.
The decision will decide more than paperwork. It will determine whether a president can narrow one of the oldest and most consequential rules of American citizenship by executive action.
