Citizenship By Birth & Derivative U.S. Citizenship

Citizenship By Birth & Derivative U.S. Citizenship


The United States follows the principle of jus soli, meaning most people born in the U.S. automatically receive U.S. citizenship. This rule generally applies to everyone except children of certain foreign diplomats.

U.S. Citizenship by Birth Abroad

Even if you were born outside the United States, you may still be a U.S. citizen through one or both parents. U.S. citizenship laws for children born abroad are complex, and some people are citizens without realizing it.

Citizenship by birth abroad depends on several factors, including:

Your date of birth

Whether one or both parents were U.S. citizens at the time of your birth

The nationality of any noncitizen parent

Your parents’ periods of physical presence in the U.S.

Your marital status at birth

Derivative U.S. Citizenship

If you were not a U.S. citizen at birth, you may have derived U.S. citizenship later. This can occur if you became a lawful permanent resident and one or both parents naturalized before you reached the required age (usually 18).

Proving U.S. Citizenship

If you believe you or a family member may be a U.S. citizen, legal guidance can help confirm eligibility. An attorney can assist with applying for a Certificate of Citizenship through USCIS or a U.S. passport through the U.S. Department of State.
