How to Apply for U.S. Citizenship Without a Lawyer

WHO CAN APPLY FOR CITIZENSHIP

Most immigrants can apply for U.S. naturalization if they meet these basic requirements. You do NOT need a lawyer to apply — millions of immigrants file on their own every year.

Standard Requirements (5-Year Rule)

• You are at least 18 years old
• You have been a lawful permanent resident (green card holder) for at least 5 years
• You have lived in the U.S. for at least 30 months out of the last 5 years (continuous residence)
• You have not taken any single trip outside the U.S. lasting more than 6 months
• You can read, write, and speak basic English
• You have good moral character (no serious criminal history)

Married to a U.S. Citizen? (3-Year Rule)

If you are married to and living with a U.S. citizen, you only need 3 years as a permanent resident — not 5. This is a significant advantage.

DOCUMENTS YOU NEED FOR N-400

Before you fill out a single line of the N-400 form, gather these documents. Missing documents are the #1 reason applications get delayed.

• 01
  Permanent Resident Card (Green Card)

  Front and back copy. This is your most important document — don't lose it.
• 02
  Passport from Your Birth Country

  All passports, including expired ones from the past 5 years. Shows your travel history.
• 03
  Tax Returns — Last 5 Years

  Federal tax returns (Form 1040). Proves you've been living and filing taxes in the U.S.
• 04
  Travel Records

  A list of every trip outside the U.S. in the past 5 years — dates, destinations, duration.
• 05
  Marriage Certificate (If Applicable)

  Required if you are applying under the 3-year rule as a spouse of a U.S. citizen.
• 06
  Divorce Decrees (If Applicable)

  If you were previously married, you need documentation of how each marriage ended.
• 07
  Two Passport-Style Photos

  Taken within the last 30 days. Available at any post office, CVS, or Walgreens.
• 08
  Filing Fee Payment

  $725 total — $640 application fee + $85 biometrics fee. Check USCIS.gov for current amounts.

HOW TO FILL OUT THE N-400 FORM

The N-400 is a 20-part form available free at USCIS.gov. Here are the sections that trip people up most often.

Part 1 — Eligibility

Part 2 — Information About You

Part 4 — Addresses and Employment

Part 5 — Travel Outside the U.S.

N-400 INTERVIEW QUESTIONS

Your USCIS officer will ask you questions from the official civics test. You need to answer at least 6 out of 10 correctly. Here are the most important ones to know:

MOST COMMON MISTAKES TO AVOID

• Leaving questions blank. If a question doesn't apply to you, write "N/A" — never leave it blank.
• Forgetting trips outside the U.S. Even a long weekend in Canada or Mexico counts. List every trip.
• Not disclosing past legal issues. USCIS will find everything. Always disclose and explain.
• Using the wrong filing address. Your USCIS filing location depends on your state. Check USCIS.gov for the correct address.
• Sending original documents. Send copies only — never your originals unless specifically requested.
• Not signing the form. An unsigned N-400 will be rejected immediately.

TIMELINE — HOW LONG DOES IT TAKE

The N-400 process typically takes 8–24 months from filing to your oath ceremony. Here's what to expect:

• Week 1–2: USCIS receives your application and sends a receipt notice
• Month 1–3: Biometrics appointment (fingerprints and photo)
• Month 6–18: Interview notice arrives
• Interview day: English test, civics test, and review of your application
• After interview: Decision — approved, continued, or denied
• Oath ceremony: You become a U.S. citizen
