Federal law lists everyone who becomes a U.S. citizen at birth in a single statute, 8 U.S.C. \u00a7 1401.1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span> U.S. citizens at birth fall into four practical groups: people born on American soil, people born abroad to one or two citizen parents who meet specific physical-presence rules, people born in most U.S. territories, and children of unknown parentage found in the United States before age five. Which rules apply to you depends on where you were born, how many of your parents were citizens, and whether your parents were married when you were born.<\/p>\n

Born on U.S. Soil<\/h2>\n

If you were born anywhere within the United States and are subject to its jurisdiction, you are a citizen at birth under 8 U.S.C. \u00a7 1401(a).1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span> The rule comes directly from the Fourteenth Amendment, which declares that all persons born in the United States and subject to its jurisdiction are citizens.2<\/a><\/sup>Legal Information Institute. 14th Amendment, U.S. Constitution<\/a><\/span><\/p>\n

The phrase “subject to the jurisdiction thereof” carves out one narrow group: children born on U.S. soil to accredited foreign diplomats, who hold diplomatic immunity and are therefore not considered subject to U.S. jurisdiction. For everyone else, birth on American soil is enough. The Supreme Court confirmed this in United States v. Wong Kim Ark<\/em> (1898), ruling that a man born in San Francisco to Chinese-national parents was a U.S. citizen even though his parents could never naturalize under the laws of that era.3<\/a><\/sup>Cornell Law School Supreme Court Collection. United States v. Wong Kim Ark, 169 U.S. 649 (1898)<\/a><\/span><\/p>\n

The statute also covers foundlings. A child of unknown parentage found in the United States before age five is presumed to be a citizen at birth, unless evidence surfaces before the child turns twenty-one showing otherwise.1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span><\/p>\n

The Status of the 2025 Executive Order<\/h3>\n

In January 2025, the president signed Executive Order No. 14160, which attempted to deny birthright citizenship to children born on U.S. soil if both parents were either unlawfully present or temporary visitors. Multiple district judges blocked it before it could take effect. A federal judge in Maryland issued a nationwide preliminary injunction, finding the order conflicted with the Fourteenth Amendment and over a century of Supreme Court precedent.2<\/a><\/sup>Legal Information Institute. 14th Amendment, U.S. Constitution<\/a><\/span> As of early 2026, the Supreme Court has agreed to review the case and the order remains on hold. The constitutional rule stands: if you are born on U.S. soil and subject to its jurisdiction, you are a citizen.<\/p>\n

Born Abroad to U.S. Citizen Parents<\/h2>\n

Birth outside the United States does not disqualify you from citizenship at birth, but the requirements are more demanding than the domestic rule, and they turn on whether both of your parents were citizens, only one was, and whether they were married. A distinction runs through all of these rules. “Physical presence” means your parent was actually on U.S. soil. “Residence” means they maintained a home in the United States. The two are not interchangeable, and confusing them is where a lot of citizenship claims run into trouble.4<\/a><\/sup>U.S. Citizenship and Immigration Services. Continuous Residence and Physical Presence Requirements for Naturalization<\/a><\/span><\/p>\n

Both Parents Are U.S. Citizens<\/h3>\n

If both parents were citizens when you were born, only one of them needs to have resided in the United States or its territories at any point before your birth. There is no minimum duration and no age requirement. This is the simplest overseas scenario.1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span><\/p>\n

One Citizen Parent and One Non-Citizen<\/h3>\n

When only one parent is a U.S. citizen and the other is a foreign national, the citizen parent must have been physically present in the United States for at least five years before the child’s birth, and at least two of those years must have come after the parent turned fourteen.5<\/a><\/sup>U.S. Department of State. Obtaining U.S. Citizenship for a Child Born Abroad<\/a><\/span> Time spent abroad on active military duty, working for the federal government, or living as the dependent of someone in those roles counts toward the physical-presence requirement.1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span><\/p>\n

A separate scenario applies when one parent is a citizen and the other is a U.S. national (someone from American Samoa or Swains Island, for instance). The citizen parent then needs only one continuous year of physical presence in the United States before the child’s birth.1<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth<\/a><\/span><\/p>\n

Children Born Abroad Out of Wedlock<\/h3>\n

When the parents are not married, 8 U.S.C. \u00a7 1409 adds another layer, and the law has historically treated citizen mothers and citizen fathers differently. A child born abroad out of wedlock to a U.S. citizen mother acquires citizenship at birth as long as the mother was physically present in the United States for one continuous year at any point before the birth.6<\/a><\/sup>Office of the Law Revision Counsel. 8 USC 1409 – Children Born Out of Wedlock<\/a><\/span><\/p>\n

For a U.S. citizen father, the bar is higher. The father must meet the same five-year physical-presence rule that applies under \u00a7 1401(g), and he must also satisfy four additional conditions before the child turns eighteen:<\/p>\n
