Birthright Citizenship: Constitutional Rules, Exceptions, and 2025 Order

Birthright citizenship is the rule that anyone born in the United States and subject to its jurisdiction is a U.S. citizen at the moment of birth, regardless of the parents’ nationality or immigration status. The rule comes from the first sentence of the Fourteenth Amendment, ratified in 1868, and was applied to children of foreign nationals by the Supreme Court in 1898. Because it sits in the Constitution rather than in an ordinary statute, it cannot be repealed by Congress or overridden by a president acting alone.

What the Constitution Says

The Citizenship Clause of the Fourteenth Amendment reads: “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.”1Congress.gov. Fourteenth Amendment Before the amendment, there was no uniform national rule; states decided who counted as a citizen, and the Supreme Court had held in Dred Scott v. Sandford (1857) that people of African descent could never be citizens.2National Archives. Dred Scott v. Sandford (1857) The amendment was written to overturn that ruling and to lock a birth-based citizenship rule into the Constitution itself so no future legislature could take it away.

Congress mirrored the constitutional text in the Immigration and Nationality Act. Under 8 U.S.C. § 1401(a), a person born in the United States and subject to its jurisdiction is a national and citizen of the United States at birth.3Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth Federal agencies use that statute when they issue passports and other citizenship documents.

What “Subject to the Jurisdiction” Means

Almost every dispute about birthright citizenship turns on those five words. Two readings have competed since the amendment was drafted.

The narrow reading treats “jurisdiction” as full political allegiance, so a child whose parents owe allegiance to a foreign government would not qualify. Supporters point to statements during the Senate debate, including Senator Lyman Trumbull’s remark that the phrase meant “not owing allegiance to anybody else.”4Congress.gov. Salvaging the Original Meaning of the Citizenship Clause

The broad reading treats “jurisdiction” as being physically present within U.S. territory and subject to U.S. law. Under this view, nearly everyone born on American soil qualifies. Senator Jacob Howard, who introduced the amendment’s language on the Senate floor, said it would “include every other class of persons” born in the country, excluding only children of foreign diplomats.

The Supreme Court adopted the broad reading in 1898, and that has been the governing interpretation ever since.

The Wong Kim Ark Decision

United States v. Wong Kim Ark is the controlling case. Wong Kim Ark was born in San Francisco in 1873 to parents who were Chinese citizens but had established a permanent home and business in the United States.5Justia U.S. Supreme Court Center. United States v. Wong Kim Ark, 169 US 649 (1898) After a trip abroad, immigration officials refused to readmit him, arguing he was not a citizen because his parents were ineligible for naturalization under the Chinese Exclusion Act.

The Court ruled 6-2 that he was a citizen. Justice Horace Gray wrote that the Fourteenth Amendment “affirms the ancient and fundamental rule of citizenship by birth within the territory” and covers “all children here born of resident aliens,” with only narrow exceptions for children of foreign diplomats, children born on foreign public ships, and children of enemies during hostile occupation. Any foreign citizen living in the United States, even temporarily, is “within the allegiance and the protection, and consequently subject to the jurisdiction, of the United States.” Parents’ nationality, race, and immigration status do not prevent their U.S.-born child from being a citizen. Because that reading rests on a constitutional amendment, ordinary legislation cannot change it.

Children of Undocumented and Temporary Residents

Wong Kim Ark’s parents were lawful residents, so the ruling did not squarely address children born to parents without legal status. The consensus since 1898, followed by every federal agency, is that the ruling’s reasoning extends to all children born on U.S. soil regardless of the parents’ immigration status. No court has held otherwise.

The strongest supporting authority is the Supreme Court’s 1982 decision in Plyler v. Doe. That case dealt with public education, but the Court directly addressed whether undocumented immigrants are “within the jurisdiction” of the United States for Fourteenth Amendment purposes. A person’s unlawful entry, the majority wrote, “cannot negate the simple fact of his presence within the State’s territorial perimeter. Given such presence, he is subject to the full range of obligations imposed by the State’s civil and criminal laws.”6Justia U.S. Supreme Court Center. Plyler v. Doe, 457 US 202 (1982) Physical presence subject to U.S. law puts a person within U.S. jurisdiction.

The State Department and USCIS have issued citizenship documents to U.S.-born children on that basis for decades. That practice was challenged by executive order in 2025.

Who Is Not Covered

The exceptions are narrow, and they track exceptions that existed under English common law before the Fourteenth Amendment.

Children of Foreign Diplomats

Children born in the United States to accredited foreign diplomatic officers do not acquire citizenship at birth. Diplomats represent their home governments and are not subject to the full legal authority of the host country; they cannot be prosecuted for most crimes, cannot be taxed as ordinary residents, and are generally immune from civil suits. Because they are not fully subject to U.S. jurisdiction in the constitutional sense, their children are not citizens.7U.S. Citizenship and Immigration Services. Chapter 3 – Children Born in the United States to Accredited Diplomats Federal regulations give these individuals a path to apply for lawful permanent resident status instead.8eCFR. 8 CFR 1101.3 – Creation of Record of Lawful Permanent Resident Status for Person Born Under Diplomatic Status in the United States

Hostile Occupation

Wong Kim Ark also recognized an exception for children “born of alien enemies in hostile occupation” of U.S. territory. It has never been applied in a reported case because no foreign military has occupied U.S. territory since the doctrine was articulated. It is a legal inheritance from English common law rather than a live concern today.

Native Americans, Historically

In Elk v. Wilkins (1884), the Supreme Court held that a Native American born as a member of a recognized tribe was not “born subject to the jurisdiction of the United States” within the meaning of the Fourteenth Amendment, even after voluntarily leaving his tribe.9Justia U.S. Supreme Court Center. Elk v. Wilkins, 112 US 94 (1884) The Court reasoned that tribal members owed immediate allegiance to their tribes. Congress ended the exclusion in the Indian Citizenship Act of 1924, which made all non-citizen Indians born within the territorial limits of the United States citizens.10National Archives and Records Administration. Indian Citizenship Act of 1924 Today, all Native Americans born in the United States are citizens at birth.

Birth in U.S. Territories

Whether the Citizenship Clause reaches unincorporated territories has not been answered by the Supreme Court applying the amendment directly. Instead, Congress has passed a separate statute for each territory:

American Samoa is the exception. People born there are “nationals, but not citizens, of the United States” under 8 U.S.C. § 1408.14Office of the Law Revision Counsel. 8 USC 1408 – Nationals but Not Citizens of the United States at Birth Non-citizen nationals can live and work anywhere in the United States, but they cannot vote in federal elections and must naturalize to become full citizens. Some American Samoans have argued in court that the Fourteenth Amendment should apply to them directly.

Because territorial citizenship rests on statute rather than the Constitution, Congress could in theory repeal it. Mainland birthright citizenship cannot be changed without a constitutional amendment.

The 2025 Executive Order and Pending Litigation

On January 20, 2025, President Trump signed an executive order titled “Protecting the Meaning and Value of American Citizenship.” It directed federal agencies to stop issuing citizenship documents to two groups of children born in the United States: those whose mothers were unlawfully present and whose fathers were not citizens or lawful permanent residents, and those whose mothers were present on temporary visas (tourist, student, or work visas) and whose fathers were not citizens or lawful permanent residents.15The White House. Protecting the Meaning and Value of American Citizenship The order was set to apply to children born 30 days after signing.

Federal courts blocked the order within weeks. Four separate district judges issued injunctions. Senior U.S. District Judge John Coughenour, ruling in a case brought by Washington, Arizona, Illinois, and Oregon, called the order “blatantly unconstitutional.” Judges in Maryland, New Hampshire, and Massachusetts followed with similar injunctions.

The litigation reached the Supreme Court. In Trump v. CASA, Justice Amy Coney Barrett wrote that the lower courts’ universal injunctions likely exceeded their authority, which addressed the reach of the injunctions rather than the underlying constitutional question. A separate challenge, Trump v. Barbara, was argued on April 1, 2026, and remains pending. The lower court in that case held that the challengers were likely to succeed on the merits.

The constitutional problem with the order is direct. The Citizenship Clause is self-executing: it does not authorize Congress to grant citizenship, it declares that persons born in the United States and subject to its jurisdiction “are citizens.” A president cannot rewrite constitutional text by executive order, and Wong Kim Ark has been the Supreme Court’s reading of that text for more than 125 years. Whether the current Court will reaffirm, modify, or overturn that precedent is the question in the pending case.

How to Prove Birthright Citizenship

For a child born in the United States, the state or territorial birth certificate is the primary proof of citizenship. Certified-copy fees vary by state and generally range from $10 to $45.

If you were born in the United States but have no birth certificate, the federal government accepts secondary evidence, including hospital birth records, baptismal certificates, census records, and early school records.16USAGov. Prove Your Citizenship: Born in the U.S. With No Birth Certificate Before relying on secondary evidence, contact the vital records office in your birth state and request a “Letter of No Record” confirming the state could not locate a certificate. That letter, combined with secondary documents, can substitute for the missing certificate when you apply for a passport or other citizenship documentation.
