The United States Citizenship and

as well as make copies of naturalization

papers.

USCIS refers to copies as "Certified

True Copies."

An appointment has to be made with

your local office to obtain "Certified True Copies."

The USCIS requires your original

naturalization certificate, and a copy.

Also, bring identification such as

a passport, or identification with

your photo on it.
