Step 1: Gather the Required Documents

Before you begin filling out Form N-400, collect all the necessary supporting documents. Missing documents can delay your application.

Document Checklist:

1. Green Card (Form I-551): A photocopy of both sides of your permanent resident card.
2. Proof of Marital Status:
   • Marriage certificate (if applying based on marriage to a U.S. citizen).
   • Divorce decrees or death certificates for previous marriages.
3. Evidence of Physical Presence:
   • Travel records, utility bills, or lease agreements proving residency.
4. Tax Returns:
   • Copies of your most recent federal income tax returns.
5. Selective Service Registration (for males 18-26): Proof of registration, if applicable.
6. Criminal Records (if applicable): Certified court dispositions for arrests or charges.

Pro Tip: Organize your documents into labeled folders for easy access during the interview process.

Step 2: Complete Form N-400

Form N-400 consists of 20 parts, each requiring accurate and thorough responses. Let’s break down some of the key sections:

Part 1: Personal Information

Provide your full legal name, aliases, and contact details. Ensure this matches the information on your green card.

Part 2: Eligibility

Indicate the basis of your eligibility (e.g., 5 years as a lawful permanent resident or 3 years through marriage).

Part 5: Residence and Employment History

List all addresses and employers for the last 5 years. Be precise and avoid gaps.

Part 9: Time Outside the U.S.

Document all trips abroad lasting 24 hours or more. Include dates, destinations, and total days.

Part 11: Good Moral Character

Answer questions about criminal history, tax compliance, and any affiliations with organizations. Be truthful, as inaccuracies can lead to denial or even legal consequences.

Step 3: Pay the Filing Fee

The current fee for Form N-400 is $640, plus an $85 biometrics fee, totaling $725. Fee waivers are available for applicants experiencing financial hardship—submit Form I-912 with your application if eligible.

Payment Options:

• Online via credit or debit card.
• By check or money order (if filing by mail).
  
  

Step 4: Submit Your Application

You can file Form N-400 online or by mail:

Online Filing:

1. Create a USCIS online account (my.uscis.gov).
2. Complete Form N-400 electronically.
3. Upload supporting documents.

Mail Filing:

1. Download the latest Form N-400 from the USCIS website.

Step 5: Attend the Biometrics Appointment

After submitting your application, USCIS will schedule a biometrics appointment at a local application support center (ASC). You’ll be notified of the date, time, and location.

At this appointment:

• USCIS collects your fingerprints, photo, and signature.

Step 6: Prepare for the Naturalization Interview

The interview is a crucial step in the naturalization process. Here’s how to prepare:

1. Review Your Application

Familiarize yourself with the answers you provided on Form N-400. USCIS officers may ask you to confirm or elaborate on specific details.

2. Study for the Civics Test

You’ll need to answer questions about U.S. history, government, and geography. USCIS provides a list of 100 possible questions—study materials are available on their website.

3. Practice English

The officer will assess your ability to read, write, and speak basic English.

Step 7: Attend the Naturalization Interview

The interview typically lasts 20–30 minutes and includes:

1. Review of Application: The officer will verify your information and ask follow-up questions.
2. Civics Test: Answer 6 out of 10 questions correctly to pass.
3. English Test:
   • Reading: Read one sentence out loud.
   • Writing: Write one dictated sentence.

Pro Tip: Stay calm and be honest. If you don’t pass, you can retake the failed portion within 60–90 days.

Step 8: Take the Oath of Allegiance

If your application is approved, USCIS will schedule an Oath of Allegiance ceremony. This is the final step to becoming a U.S. citizen.

What to Expect at the Ceremony:

• Check-in with your oath ceremony notice.
• Return your green card.
• Receive your naturalization certificate—your official proof of U.S. citizenship.

Pro Tip: Double-check the information on your certificate before leaving the ceremony.
