Certificate of Naturalization
Your certificate of naturalization number appears in red on the certificate. If you lose your certificate of naturalization or if it is damaged and you need to replace it, you must submit Form N-565 to the USCIS. If you must replace it because of USCIS clerical errors or a misstatement of facts, there is no fee. You can update your certificate if you change your name through marriage or divorce or change your gender, but fees apply.
