How To Get Proof of U.S. Citizenship

In order to qualify for the benefits of being a U.S. citizen, one must be able to provide proof of citizenship.


Proof of citizenship can be documented in a variety of ways. Among the most common documents that establish US citizenship are:


* A U.S. Birth Certificate;

* A U.S. Passport;

* A Certificate of Citizenship; and

* A Naturalization Certificate.



If you were born in the United States, you were a US citizen at birth. You do not need to apply to USCIS for any evidence of citizenship. Your birth certificate (issued where you were born) is proof of your citizenship.


If you are not a U.S. citizen by birth or did not acquire U.S. citizenship automatically after birth, you may still be eligible to become a citizen through the normal naturalization process. Qualifying individuals who are 18 years and oder may submit an “Application for Naturalization” (N 400 Form) to become naturalized citizens. If you are already a naturalized U.S. citizen, then a copy of your naturalization certificate will prove your citizenship.
