Understanding Form N-400: Application for Naturalization

Who Should File Form N-400?

You may be eligible to file Form N-400 if you meet one of the following criteria:

  • Permanent residents for at least 5 years: Individuals who have held a green card for at least 5 years.
  • Spouses of U.S. citizens: You may file after 3 years of permanent residence if you have been married to and living with your U.S. citizen spouse for the duration.

Additional eligibility criteria include having good moral character, being proficient in English, and passing the U.S. civics test.

Required Supporting Documents

When submitting Form N-400, you will need to provide the following:

  • A copy of your green card (front and back).
  • Passport-style photos taken within the last 30 days.
  • Documents supporting your current marital status (e.g., marriage certificates, divorce decrees).
  • Proof of legal name changes, if applicable.
  • If applicable, proof of selective service registration.

If any of your supporting documents are in a language other than English, you must provide certified translations to comply with USCIS requirements. Certling offers certified translation services that meet these standards to ensure your application is processed smoothly.
