Under the Fourteenth Amendment, birthright citizenship means that almost anyone born on U.S. soil is a U.S. citizen from the moment of birth, regardless of the parents’ nationality or immigration status. The rule sits in the Constitution itself, has been in force since 1868, and was confirmed by the Supreme Court in 1898. Changing it would take a constitutional amendment, not an ordinary law or executive order.
What the Citizenship Clause Actually Says
Section 1 of the Fourteenth Amendment opens with a single sentence that carries the entire rule: “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.”1National Archives. 14th Amendment to the U.S. Constitution: Civil Rights
Legal scholars describe the clause as self-executing. Congress does not need to pass a follow-up law to make it work, and it cannot quietly redefine who counts as a citizen through ordinary legislation. Any real change to the baseline would have to go through Article V, which requires a two-thirds vote in both chambers of Congress and ratification by at least 38 state legislatures.2Library of Congress. Overview of Article V, Amending the Constitution That threshold has been cleared 27 times in the country’s history.
No application, no approval, no waiting period. Citizenship attaches at birth.
Who Qualifies at Birth
The clause does not say “all persons born in the United States” and stop. It adds “subject to the jurisdiction thereof,” and for more than a century courts have read that phrase broadly. The controlling case is United States v. Wong Kim Ark (1898), where the Supreme Court held that a child born in San Francisco to Chinese parents who were long-term residents and business owners was a U.S. citizen at birth.3Justia U.S. Supreme Court Center. United States v. Wong Kim Ark, 169 U.S. 649 (1898) The parents’ foreign citizenship did not matter. What mattered was that the family lived and worked under American law.
Under Wong Kim Ark, a child born in the United States to tourists, students, temporary workers, or undocumented immigrants is a citizen at birth. The State Department’s Foreign Affairs Manual treats this as one of the two paths to citizenship at birth, alongside jus sanguinis, or citizenship acquired through a U.S. citizen parent.4U.S. Department of State Foreign Affairs Manual. 8 FAM 301.1 – Acquisition by Birth in the United States
The Narrow Exceptions
A handful of situations fall outside the rule because the “subject to the jurisdiction” qualifier is not satisfied. They are rare in practice.
Children of accredited foreign diplomats. Diplomatic officers hold sovereign immunity under international law and are not fully subject to U.S. legal authority, so a child born to such a diplomat in the United States does not acquire citizenship under the Fourteenth Amendment.5U.S. Citizenship and Immigration Services. Chapter 3 – Children Born in the United States to Accredited Diplomats
Children of members of a hostile occupying force. In the rare scenario of enemy troops occupying U.S. territory, a child born to those forces would not gain birthright citizenship. The exception has not been tested in modern times.
Members of Native American tribes, historically. In Elk v. Wilkins (1884), the Supreme Court held that Native Americans born as members of tribal nations were not automatically citizens under the Fourteenth Amendment because their primary allegiance ran to the tribe. Congress resolved this in the Indian Citizenship Act of 1924, which declared all Native Americans born within the United States to be citizens.6National Archives. Indian Citizenship Act of 1924
Outside these situations, the rule is close to universal.
Where the Rule Applies
The Fourteenth Amendment applies with full force across all 50 states and the District of Columbia. A birth anywhere within those borders triggers citizenship automatically, and there is no distinction between states. The geographic reach also extends to U.S. territorial waters, which stretch 12 nautical miles from the coastline under a 1988 presidential proclamation.7Ronald Reagan Presidential Library. Proclamation 5928 – Territorial Sea of the United States A birth aboard a vessel inside that zone falls under U.S. jurisdiction. Births in U.S. airspace present a murkier question. The general principle of jus soli would seem to apply, but there is no definitive court ruling on it, and the parents’ citizenship and the specific circumstances both factor in.
U.S. Territories: Same Result, Different Source
People born in Puerto Rico, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands are U.S. citizens at birth, but their citizenship comes from federal statute rather than the Fourteenth Amendment. The statute doing the work is 8 U.S.C. § 1401, which lists every category of person who qualifies as a citizen at birth.8Office of the Law Revision Counsel. 8 U.S.C. 1401 – Nationals and Citizens of United States at Birth The Supreme Court drew this line through the Insular Cases, a series of early-twentieth-century decisions holding that the Constitution does not fully extend to unincorporated territories. In practice, territorial citizens hold U.S. passports, live and work anywhere in the country, and qualify for federal benefits like anyone else.
American Samoa: Nationals, Not Citizens
American Samoa is the exception among the territories. People born there are classified as U.S. nationals rather than citizens under 8 U.S.C. § 1408. A national owes permanent allegiance to the United States and can carry a U.S. passport, but cannot vote in federal elections or hold certain government positions.9Office of the Law Revision Counsel. 8 U.S.C. 1408 – Nationals but Not Citizens of the United States at Birth In Fitisemanu v. United States, three American Samoan residents argued that the Citizenship Clause should apply to them; the Tenth Circuit disagreed, and the Supreme Court declined review in October 2022.10Justia. Fitisemanu v. United States American Samoan nationals who want full citizenship can naturalize after meeting standard residency requirements, including five years of U.S. residence.11U.S. Citizenship and Immigration Services. Chapter 2 – Becoming a U.S. Citizen
The 2025 Executive Order and Where Things Stand
On January 20, 2025, President Trump signed an executive order titled “Protecting the Meaning and Value of American Citizenship,” which directed federal agencies to stop issuing citizenship documents for children born in the United States when both parents lacked permanent legal status. The order targeted two categories: children whose mothers were unlawfully present and whose fathers were not citizens or lawful permanent residents, and children whose mothers were in the country on temporary visas with fathers who were likewise not citizens or permanent residents.12The White House. Protecting The Meaning And Value Of American Citizenship
Attorneys general from more than 20 states sued, and multiple federal district courts issued nationwide injunctions blocking enforcement. Every court that has reached the merits has concluded that the order violates the Citizenship Clause and contradicts the Immigration and Nationality Act.13Congress.gov. Birthright Citizenship: Litigation Status Update
On June 27, 2025, in Trump v. CASA, Inc., the Supreme Court partially stayed the lower-court injunctions, ruling that their universal scope likely exceeded judicial authority. The Court did not rule on whether the executive order itself was constitutional.14Supreme Court of the United States. Trump v. CASA, Inc. The Court then took up Barbara v. Trump, hearing oral arguments on April 1, 2026, with a decision on the constitutional question expected by mid-2026.13Congress.gov. Birthright Citizenship: Litigation Status Update The executive order remains blocked, and no child has been denied a birth certificate or citizenship documentation under it. Wong Kim Ark has stood for over 125 years, and no court reviewing the merits has found the order lawful.
Proving Your Citizenship
Being a citizen and proving you’re a citizen are two different problems. The Constitution confers the status, but you still need documents to get a passport, register to vote, or prove work eligibility.
The strongest proof is a U.S. passport, even an expired one, or a certified birth certificate issued by the city, county, or state where you were born. A valid birth certificate must include your full name, date and place of birth, your parents’ names, the registrar’s signature, a filing date within one year of birth, and the issuing authority’s seal.15U.S. Department of State. Citizenship Evidence Some states issue abbreviated birth abstracts that leave out some of these details. If yours falls short, request a long-form certificate showing the original record.
If no birth certificate exists at all, the process gets harder but not impossible. You can use a delayed birth certificate (one filed more than a year after birth) backed by early documentation such as a baptism certificate, hospital record, or school enrollment. If no record of any kind is on file, you’ll need a Letter of No Record from the state registrar combined with at least two early documents and a sworn birth affidavit on Form DS-10.15U.S. Department of State. Citizenship Evidence Fees for certified copies vary by state, generally between $10 and $30.
