Becoming a U.S. citizen is a significant milestone—offering more security, rights, and peace of mind for you and your family. This complete guide walks you through Form N-400 (Application for Naturalization) step by step, updated for 2025, so that you can navigate the process with confidence.
1. Am I Eligible for Naturalization?
Before starting the N-400, make sure you meet the key requirements:
- Permanent Resident (Green Card Holder) for:
- 5 years, or
- 3 years if married to a U.S. citizen.
- Continuous residence and physical presence in the U.S.
- Good moral character (generally, no serious criminal history).
- English proficiency (reading, writing, speaking).
- Knowledge of U.S. government and history (civics).
- Attachment to the Constitution, meaning you must support the beliefs and values of the U.S.
If you’re unsure, consulting a family-based immigration attorney can help clarify if you meet the criteria or if any exceptions apply (e.g., military service, qualifying out-of-country residence).
2. Understand the 2025 Filing Fee & Fee Waivers
As of 2025, the Form N-400 filing fee is approximately $725—which includes the $640 application and the $85 biometric services fee.
- Low-income applicants might be eligible for a fee waiver using Form I-912.
- Some applicants can request a fee reduction via Form I-942.
Always check the USCIS website for the current fee schedule when filing.
3. Gather Required Documents
Having your documents in order can streamline your application:
- Form N-400 (fillable PDF or online USCIS account).
- ** Copy of your Green Card (front and back).**
- Photos (if filing by paper) following USCIS photo guidelines.
- Evidence of continuous residence if you’ve been outside the U.S. for 6 months or more (e.g., lease, utility bills).
- Tax returns, if required (especially if you’re asking for a fee waiver or adjustment due to taxes).
- Documentation of name or marital status changes (marriage certificate, divorce decree).
- Selective Service registration, if applicable (for males aged 18–26 when you became a permanent resident).
Sauce: USCIS instructions on N-400 and I-912.
4. Complete and Submit Form N-400
You can file online via the USCIS online account system or submit via mail:
- Online filing tends to be faster and lets you track your case easily. You’ll upload your documents directly.
- Paper filing requires a completed PDF, required signatures, and mailed packet.
Be sure to answer all questions fully and accurately. The form covers parts like:
- Personal information (address, employment, travel history).
- Moral character questions (e.g., criminal history, tax compliance).
- English and civics testing eligibility.
- Oath preference (English or another language).
5. Attend Biometric Appointment
After filing, USCIS will send a biometric appointment notice requiring you to attend a USCIS Application Support Center (ASC).
- Bring your appointment notice, valid ID, and Green Card.
- They collect fingerprints, photograph, and signature for background checks.
6. Prepare for the Naturalization Interview & Civics, English Tests
Expect to receive an interview notice with date/time in the mail or through your online account.
At the interview, you will:
- Review your application with an immigration officer.
- Take the English test:
- Reading: read one simple sentence aloud.
- Writing: write one simple sentence (36–38 characters).
- Speaking: answer questions about your application.
- Take the Civics test — 10 questions from a pool of 100 U.S. civics questions. You must answer at least 6 correctly.
- 2025 update: USCIS updated the civics question set but retained the 10-question test format.
If you have disability or qualify for a 65/20 exception (65+ years old with 20+ years as a permanent resident), you may not need to take the full test.
7. Respond to USCIS Requests & Interview Results
- If USCIS needs more evidence (Request for Evidence, or RFE), respond promptly with requested documents.
- At the interview, the officer may approve, deny, or continue your application:
- Continue if additional documents or retesting are needed.
8. Take the Oath of Allegiance & Receive Your Certificate
Once approved, USCIS will send a Oath Ceremony Notice. At the ceremony:
- You’ll take the Oath of Allegiance.
- You’ll receive your Certificate of Naturalization on the spot or via mail.
Congratulations—you’re now a U.S. citizen!
9. After Naturalization: What’s Next?
- Apply for your U.S. passport (Form DS-11).
- Register to vote in your state.
- Update your driver’s license, Social Security, and other official records with your new citizenship status.
