How and When to Apply for U.S. Citizenship

Most green card holders can file Form N-400 after 5 years of continuous residence. Filing at the right time, with the right documentation, is what separates a smooth approval from months of delays, RFEs, or denials.

Naturalization is the legal process by which a foreign-born permanent resident becomes a U.S. citizen. Once naturalized, you gain full and equal standing under the law, including the right to vote, hold a U.S. passport, petition for family members, and access federal benefits unavailable to non-citizens. To qualify, you generally must be a lawful permanent resident for at least 5 years (or 3 years if married to a U.S. citizen), meet continuous residence and physical presence requirements, pass an English and civics test, and demonstrate good moral character.

Before filing Form N-400, review all U.S. citizenship requirements, check whether you qualify for exceptions to the English and civics test, and if you have any past criminal history, read about how criminal records affect naturalization eligibility. Contact our office to evaluate your eligibility before you file.

The N-400 Naturalization Process, Step by Step

  1. File Form N-400. Submit your Application for Naturalization with required supporting documents and the USCIS filing fee. Accuracy here matters — errors are a leading cause of delays and RFEs.
  2. Biometrics appointment. USCIS will schedule you for fingerprinting at a local Application Support Center. Your fingerprints are submitted to the FBI for a background check.
  3. USCIS interview. An officer reviews your application, tests your English, and administers the civics exam. If you meet all requirements, you are scheduled for the oath ceremony.
  4. Oath of Allegiance. You become a U.S. citizen the moment you take the Oath of Allegiance, renouncing prior allegiances and pledging to support the Constitution.

When to Apply for Naturalization

An applicant filing under the general naturalization provision may file his or her application up to 90 days before he or she would first meet the required 5-year period of continuous residence as a legal permanent resident. Although an applicant may file early according to the 90 day early filing provision, the applicant is not eligible for naturalization until he or she has reached the required 5 year period of continuous residence as a legal permanent resident.


USCIS calculates the early filing period by counting back 90 days from the day before the applicant would have first satisfied the continuous residence requirement for naturalization. For example, if the applicant would satisfy the five-year continuous residence requirement for the first time on June 10, 2015 USCIS will begin to calculate the 90-day early filing period from June 9, 2015. In such a case, the earliest that the applicant is allowed to file would be March 12, 2015 (90 calendar days earlier).
