Apply for Citizenship
10 Steps to Naturalization: Understanding the Process of Becoming a U.S. Citizen
To apply for naturalization, you will need to file Form N-400, Application for Naturalization. Below you will find a general description of the application process.
Before you apply, be sure that you meet all eligibility requirements. Check if you qualify for any exceptions and accommodations. You can use the naturalization eligibility worksheet and document checklist to help you prepare.
General Steps in the Naturalization Process
Step 1. Determine if you are already a U.S. citizen.
What to do: If you are not a U.S. citizen by birth, or you did not acquire or derive U.S. citizenship from your parent(s) automatically after birth, go to the next step.
Step 2. Determine if you are eligible to become a U.S. citizen.
What to do: Review the naturalization eligibility worksheet to help you decide if you are eligible to apply for naturalization.
Step 3. Prepare your Form N-400, Application for Naturalization.
What to do: Download the form and read the instructions. Get 2 passport-style photos and collect the necessary documents to demonstrate your eligibility for naturalization. Use the document checklist to make sure you collect all the required documents.
Step 4. Submit your Form N-400, Application for Naturalization.
Once you submit Form N-400, USCIS will send you a receipt notice. You can check current processing times and the status of your application online or by calling the National Customer Service Center at 1-800-375-5283 or 1-800-767-1833 (hearing impaired).
Step 5. Go to the biometrics appointment, if applicable.
What to do: If you need to take biometrics, USCIS will send you an appointment notice that includes your biometrics appointment date, time, and location. Arrive at the designated location at the scheduled time. Have your biometrics taken.
Step 6. 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. You must report to the USCIS office at the date and time on your appointment notice. Please bring the appointment notice with you.
Step 7. Receive a decision from USCIS on your Form N-400, Application for Naturalization.
USCIS will issue you a written notice of decision.
Step 8. Receive a notice to take the Oath of Allegiance.
What to expect: If USCIS approved your Form N-400 in step 7, you may be able to participate in a naturalization ceremony on the same day as your interview. If a same day naturalization ceremony is unavailable, USCIS will mail you a notification with the date, time, and location of your scheduled ceremony.
Step 9. Take the Oath of Allegiance to the United States.
You are not a U.S. citizen until you take the Oath of Allegiance at a naturalization ceremony.
What to do: Complete the questionnaire on Form N-445, Notice of Naturalization Oath Ceremony. Report for your naturalization ceremony and check in with USCIS. A USCIS officer will review your responses to Form N-445. Turn in your Permanent Resident Card (Green Card). Take the Oath of Allegiance to become a U.S. citizen. Receive your Certificate of Naturalization, review it, and notify USCIS of any errors you see on your certificate before leaving the ceremony site.
