An application for citizenship is typically filed by an immigrant who has been a permanent resident in the US for five years. The application for citizenship consists of USCIS form N-400 and any required documentation or evidence. The application for citizenship and filing fee is mailed to a designated mailbox and processed by immigration officials. The citizenship application is then forwarded to the local USCIS office that handles applications for the applicant’s region of residence so that a fingerprint session and citizenship interview can be scheduled. A naturalization attorney can assist in filing an application for citizenship. See our N-400 citizenship application section for more information.
