Birthright Citizenship in the USA and the Supreme Court 2025

Birthright Citizenship

Birthright citizenship in the United States is a fundamental principle of American citizenship law. It guarantees that anyone born on U.S. soil automatically acquires U.S. citizenship, regardless of their parents’ citizenship or immigration status. This principle is enshrined in the 14th Amendment of the U.S. Constitution and has been the subject of interpretation by the U.S. Supreme Court over time.

This article provides a clear, detailed, and neutral overview of birthright citizenship, its constitutional foundation, key Supreme Court rulings, and practical implications.


What is Birthright Citizenship?

Definition and General Understanding

Birthright citizenship, also known by the Latin term “jus soli”—which translates to “right of the soil”—is a legal principle under which a person automatically acquires citizenship of a country simply by being born within its territorial boundaries. This doctrine is distinct from jus sanguinis (“right of blood”), which grants citizenship based on the nationality or ethnicity of one’s parents, regardless of place of birth.

In the context of the United States, birthright citizenship means that any child born within the borders of the country is granted U.S. citizenship at birth. This applies to all 50 states, the District of Columbia (Washington, D.C.), and the U.S. territories, which include Puerto Rico, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands. The status is granted regardless of the citizenship or immigration status of the child’s parents. In other words, even if a child’s parents are foreign nationals or undocumented immigrants, the child is still entitled to full U.S. citizenship if born on U.S. soil—so long as they are “subject to the jurisdiction” of the United States, as stated in the 14th Amendment.

This foundational concept plays a significant role in defining national identity and shaping immigration policy in the U.S. It provides immediate legal rights to those born in the country, including eligibility for a U.S. passport, the right to vote upon reaching adulthood, and protection under U.S. laws and constitutional rights from birth.

The 14th Amendment and Birthright Citizenship

The 14th Amendment, ratified in 1868, is the constitutional basis for birthright citizenship in the U.S. It states:

“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.”

This provision was originally intended to protect the citizenship rights of former slaves but applies broadly to all persons born in the U.S. under its jurisdiction.


Historical Background and Early Interpretations

Citizenship Before the 14th Amendment

Before the 14th Amendment, citizenship laws varied by state, and the U.S. Constitution did not explicitly define citizenship beyond “natural-born” status for presidential eligibility.

The Slaughter-House Cases (1873)

One of the early Supreme Court cases discussing the 14th Amendment was the Slaughter-House Cases. Although it addressed citizenship rights, it did not directly resolve questions about birthright citizenship.

United States v. Wong Kim Ark (1898)

A landmark ruling, United States v. Wong Kim Ark, involved a man born in San Francisco to Chinese immigrant parents. When Wong Kim Ark returned from abroad, he was denied re-entry on the claim he was not a citizen. The Supreme Court ruled in his favor, affirming that the 14th Amendment grants citizenship to nearly everyone born on U.S. soil, except certain limited exceptions.


Key Supreme Court Decisions on Birthright Citizenship

United States v. Wong Kim Ark (1898)

  • Issue: Whether a child born in the U.S. to foreign parents is a citizen.
  • Ruling: The Court confirmed birthright citizenship for persons born in the U.S. under its jurisdiction, except children of foreign diplomats or enemy forces.
  • Importance: This remains the definitive case establishing birthright citizenship.

Plyler v. Doe (1982)

Though not directly about birthright citizenship, Plyler v. Doe reaffirmed equal protection under the 14th Amendment by ruling that states cannot deny public education to children based on undocumented status, emphasizing constitutional protections tied to residency and citizenship.


Constitutional Interpretation and Legal Criteria

“Subject to the Jurisdiction Thereof”

This phrase in the 14th Amendment means:

  • A person must be subject to U.S. laws and authority at birth.
  • Children of foreign diplomats or occupying forces are excluded due to immunity or lack of jurisdiction.

Exceptions to Birthright Citizenship

Limited exceptions exist:

  • Children of foreign diplomats.
  • Children born to hostile occupying forces.

Contemporary Supreme Court Stance and Issues

The Supreme Court of the United States has consistently upheld the principle of birthright citizenship, especially as it was clearly defined in the landmark 1898 decision, United States v. Wong Kim Ark. In that case, the Court ruled that a child born in the U.S. to foreign parents, who were lawfully residing in the country, was indeed a U.S. citizen under the 14th Amendment. This decision set a powerful and lasting precedent that has guided citizenship law in the United States for over a century.

Since then, no major Supreme Court ruling has reversed or weakened this interpretation. In fact, the Court has avoided taking up recent challenges that attempt to reinterpret or restrict birthright citizenship, thereby reinforcing the legal stability of the doctrine. Legal scholars, constitutional experts, and the judiciary continue to recognize Wong Kim Ark as the authoritative source on the issue.

The lack of any recent changes or opposing decisions by the Supreme Court highlights the firm constitutional foundation of birthright citizenship. It remains a settled area of law, providing certainty for millions of Americans and maintaining consistency in how citizenship is determined in the United States.

Common Questions About Birthright Citizenship

  • Do children of undocumented immigrants born in the U.S. get citizenship?
    Yes, they do, following the Supreme Court’s ruling in Wong Kim Ark.
  • Are children born to foreign diplomats U.S. citizens?
    No. Due to diplomatic immunity, these children are not subject to U.S. jurisdiction and do not acquire citizenship by birth.
  • Can Congress change birthright citizenship?
    No. Birthright citizenship is constitutionally protected and can only be changed via a constitutional amendment.

Birthright citizenship is a deeply rooted and well-established constitutional right in the United States, forming a core part of the nation’s identity and legal framework. This principle is anchored in the 14th Amendment to the U.S. Constitution, which was ratified in 1868 in the aftermath of the Civil War. The amendment explicitly states that “all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” This powerful and unambiguous clause ensures that nearly every person born on American soil, regardless of their parents’ immigration status or nationality, is automatically granted full U.S. citizenship at birth.

The Supreme Court has repeatedly upheld this right, most notably in the landmark 1898 case United States v. Wong Kim Ark, which confirmed that even children born to foreign nationals are entitled to U.S. citizenship if born within the country’s jurisdiction. Through such rulings, the Court has helped solidify birthright citizenship as a constitutional guarantee.

This principle brings clarity and consistency to U.S. citizenship law, removing ambiguity around who qualifies as an American from birth. It also plays a crucial role in protecting the civil, political, and legal rights of millions of individuals born each year in the U.S., ensuring they can fully participate in society, access education and healthcare, vote upon reaching adulthood, and receive equal protection under the law.
