What Is Birthright Citizenship?

Birthright citizenship is the principle that people born in the United States are Americans—full members of our society from the moment they are born. It reflects a simple and powerful idea: if you’re born here, you belong here. In the United States, birthright citizenship is guaranteed by the Fourteenth Amendment to the Constitution, adopted in 1868 in the aftermath of the Civil War. The amendment 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 constitutional guarantee was intentionally written to ensure equality under the law, regardless of race, ancestry, or parentage. It was enacted to overturn the Supreme Court’s infamous 1857 Dred Scott decision, which had declared that Black people born in the United States could never be citizens.

How Birthright Citizenship Works in the United States

The United States recognizes two primary paths to citizenship at birth:

Birthplace‑Based Citizenship (Jus Soli)

The U.S. follows a principle known as jus soli, or “right of the soil,” meaning that nearly everyone born on U.S. soil is a U.S. citizen, regardless of their parents’ immigration status. The Supreme Court confirmed this interpretation over a century ago, in United States v. Wong Kim Ark (1898), holding that children born in the U.S. to immigrant parents are citizens at birth. The only narrow exceptions are children born to foreign diplomats, who are not considered “subject to the jurisdiction” of the United States.

Ancestry‑Based Citizenship (Jus Sanguinis)

U.S. law also allows children born abroad to U.S. citizens to acquire citizenship through their parents, provided certain legal requirements are met. Together, these rules create a clear, fair, and race‑neutral standard for who is an American—one that does not depend on lineage, wealth, or skin color.

Why Birthright Citizenship Matters

It Guarantees Equality and Prevents a Two‑Tiered Society

Birthright citizenship ensures that all people born in the United States are treated equally under the law. Weakening or ending this principle would create a dangerous two‑tiered system in which some U.S.‑born children could be denied citizenship because of who their parents are. Millions of U.S. citizen children have at least one immigrant parent. Stripping birthright citizenship could leave many children stateless or vulnerable to deportation from the only country they have ever known.

It Strengthens Belonging and Social Cohesion

Birthright citizenship promotes a shared sense of belonging. When people are recognized as full members of society, they are more likely to invest in their communities, pursue education and careers, and participate in civic life. This inclusion strengthens democracy and brings communities together. Creating a permanent subclass of people who grow up in the U.S. but are denied full membership undermines national unity and weakens the social fabric.

It Reflects Core American Values

Birthright citizenship embodies deeply held American ideals of fairness, opportunity, and non‑discrimination. It affirms that citizenship is not inherited through bloodlines or ancestry, but grounded in shared commitment and equal rights. Most countries in the Western Hemisphere recognize some form of birthright citizenship. Ending it would make the United States an outlier and betray a long‑standing constitutional tradition.

Birthright Citizenship and the Courts Today

Birthright citizenship has been settled law for more than 125 years. Ending or limiting it would require either:

• A constitutional amendment (which requires approval by two‑thirds of Congress and ratification by three‑quarters of the states), or
• A radical departure by the Supreme Court from long‑standing precedent interpreting the Fourteenth Amendment.

While political actors have periodically called for restricting birthright citizenship through legislation or executive action, such efforts would conflict with the Constitution as it has consistently been interpreted. As courts consider renewed challenges, what is at stake is not just a legal doctrine—but a foundational promise of equality and belonging.

Bottom Line

Birthright citizenship provides a simple, fair, and unifying rule: if you are born in the United States, you are an American. It ensures equal treatment under the law, prevents statelessness, strengthens communities, and reflects our nation’s highest ideals. Protecting birthright citizenship means protecting the idea that everyone belongs—and that our future is stronger when we uphold equality for all.
