How to Apply for US Citizenship

1 Determine if you are eligible to become a US citizen

Take our Citizenship Eligibility Test to help you decide if you are eligible to apply for naturalization.

2 Prepare your Application for Naturalization

Fill out Form N-400 (Application for Naturalization).

Collect all necessary documents to demonstrate your eligibility for naturalization:

3 Submit the Application for Naturalization

Once you submit Form N-400, USCIS will send you a receipt notice.

4 Go to the biometrics appointment

If USCIS determines that you need to take biometrics, they will send you an appointment notice that includes the date, time, and location of your appointment.

5 Complete the interview

Once all the preliminary processes on your case are complete, USCIS will schedule an interview with you to complete the naturalization process. Learn more about the Naturalization Interview.

6 Receive a decision from USCIS

USCIS will issue you a written notice of decision. If your application is approved, you will also receive a notice to take the Oath of Allegiance.

7 Take the Oath of Allegiance to the United States

You are not a US citizen until you take the Oath of Allegiance at a naturalization ceremony.
