How do I send my application to USCIS?

Mail your completed N-400, photos, fee (or fee waiver application), and any other required documents to the correct address listed in the N-400 instructions at the USCIS website.

If you are in the military, mail it to the address listed for military applicants.

Next Steps…

• Review, print, and sign your completed Form N-400.
• Click Gather Documents to make sure you have all the required documents. If any of those documents is not in English, you must also send an English translation.
• Include a check, money order, or your application for a fee waiver.
• Mail your application, documents, and fee/fee waiver to the correct address: https://www.uscis.gov/n-400
• Important! Make copies of all pages of your N-400 form and the required documents. Keep these for your records.

How to Prepare

• After you apply, USCIS will send you a Receipt Notice to say they received your application. If they need more information or documents, they will send another letter.
• Later, they will mail you information about a biometrics appointment and your citizenship interview (also called the test). Do NOT miss this appointment!
