Quick Summary
Birthright citizenship is the legal principle that anyone born on US soil automatically becomes a US citizen, regardless of their parents’ immigration status. It is guaranteed by the Citizenship Clause of the 14th Amendment and has remained a settled feature of American law for more than 150 years, reaffirmed most recently by the Supreme Court in its June 2026 ruling in Trump v. Barbara.
What Birthright Citizenship Means
Birthright citizenship follows a legal principle known as jus soli, Latin for “right of the soil,” under which citizenship is determined by where a person is born rather than the citizenship of their parents. With very narrow exceptions, such as children born to foreign diplomats with immunity, anyone born within US territory is automatically a US citizen at birth, with no application or naturalization process required.
This stands in contrast to many other countries, which rely primarily on jus sanguinis, or “right of blood,” where citizenship passes through parents rather than birthplace. The US recognizes both principles simultaneously.
The Legal Foundation: The 14th Amendment
The constitutional basis for birthright citizenship is the Citizenship Clause of the 14th Amendment, ratified in 1868, which states that all persons “born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” The amendment was adopted after the Civil War specifically to overturn the Supreme Court’s 1857 Dred Scott decision and to guarantee citizenship to formerly enslaved people and their descendants.
The Supreme Court gave the clause its most influential interpretation in the 1898 case United States v. Wong Kim Ark. Wong was born in San Francisco to Chinese immigrant parents barred from naturalizing under the Chinese Exclusion Act. When denied reentry after a trip abroad, the Court ruled he was a citizen by birth, establishing that children born on US soil to noncitizen parents are covered by the Citizenship Clause, a precedent that has stood for well over a century.
How It Works in Practice
A birth certificate showing a US place of birth is generally sufficient proof of citizenship, regardless of the immigration status of the parents. Narrow exceptions exist for children born to foreign diplomats with accredited immunity, and historically for some Native Americans on tribal land until Congress extended citizenship to all Native Americans in 1924.
Common Misconceptions
A frequent misconception is that birthright citizenship allows parents to gain legal status simply because their child is a US citizen. In reality, a US-citizen child does not confer any immigration benefit on their parents until the child turns 21 and can sponsor a parent, and even that does not protect parents from deportation in the interim.
Another common misunderstanding involves the term “anchor baby.” While a practice sometimes described as “birth tourism” does exist, it is legally distinct from unauthorized immigration, and US authorities pursue fraud-based prosecutions against organized schemes without altering the underlying constitutional guarantee of citizenship for the child.
Recent Legal Challenges
Birthright citizenship faced its most significant legal test in decades after Trump signed an executive order in January 2025 seeking to deny citizenship to children born to undocumented or temporarily present parents. Every federal court that reviewed the order found it unconstitutional. The Supreme Court ruled 6-3 in June 2026 in Trump v. Barbara that the order violated the 14th Amendment, reaffirming Wong Kim Ark.
Why It Matters
Birthright citizenship affects an estimated 255,000 children born in the US each year to noncitizen parents. For these families, automatic citizenship provides immediate legal status, access to public education, and eventual eligibility to vote and hold most federal jobs.
