Learn the steps for becoming a U.S. citizen including how to apply, sample test questions and what is the naturalization process. Also, find information on dual citizenship, how to get proof of your U.S. citizenship if you were born abroad or replace your lost or stolen citizenship certificate.
Dual citizenship (or dual nationality) means a person may be a citizen of the United States and of another country at the same time. U.S. law does not require a person to choose one citizenship or another.
If you were born outside the United States and your U.S. parent(s) did not register your birth at the U.S. Embassy or consulate, you may apply for a U.S. passport, but you will need:
Your foreign birth record showing your parents' names
Evidence of your parent(s) U.S. citizenship
Your parents' marriage certificate
If you were born outside the U.S. and your U.S. parent(s) registered your birth with a U.S. Embassy, the U.S. Department of State (DOS) will be able to help you get a copy of a Consular Report of Birth Abroad (Form FS-240).
U.S. Citizenship for People Born Abroad or in U.S. Territories
You are a U.S. citizen if:
You have a birth certificate issued by a U.S. state.
You were born in a U.S. territory and have a birth certificate issued by that territory. If you don't have a birth certificate from your birth territory, you may be able to verify your citizenship status using other documents.
You were born outside of the U.S. to at least one U.S. citizen parent and your parent(s) recorded your birth with the U.S. Embassy or consulate in that country.
