What are the naturalization requirements? Continuous residence, physical presence, and good moral character

Naturalization requires three main requirements: continuous residence, physical presence, and good moral character. Under INA 316(a), an applicant must have resided continuously in the United States for at least 5 years and be physically present for at least half of that period (913 days) before filing Form N-400. Good moral character must be demonstrated during the statutory period, measured against the standards of the average citizen.

Details / How it works

Continuous Residence requires the applicant to maintain a permanent dwelling place in the United States for the statutory period (generally 5 years under INA 316(a) or 3 years for certain spouses under INA 319(a)). USCIS reviews records and testimony to determine compliance. Physical Presence is a separate requirement: the applicant must be physically present in the United States for at least half the continuous residence period (at least 30 months or 913 days under INA 316(a)). Departure and return days count as physical presence. Good Moral Character (GMC) means character that measures up to the standards of average citizens of the community. The applicant must show GMC during the statutory period and up to the time of the Oath of Allegiance. USCIS evaluates the applicant's record, statements, and testimony on a case-by-case basis. Certain criminal conduct automatically precludes a finding of GMC.

Numbers & thresholds

Requirement Statutory Period Numerical Threshold
Continuous Residence 5 years (INA 316) or 3 years (INA 319(a)) Absence >6 months but <1 year presumptively breaks continuity; absence ≥1 year automatically breaks continuity.
Physical Presence Same as continuous residence period At least 30 months (913 days) in the United States before filing under INA 316(a).
Good Moral Character The applicable statutory period (e.g., 5 years under INA 316) No fixed numerical threshold; evaluated by standards of average citizens. INA 101(f) lists conduct that precludes GMC.

Exceptions & edge cases

Exceptions to Continuous Residence: Certain classes of applicants may be eligible for a reduced period of continuous residence, constructive continuous residence while outside the United States, or an exemption from the continuous residence requirement. These include certain military members and certain spouses of U.S. citizens. An applicant with an approved Form N-470 (Application to Preserve Residence for Naturalization Purposes) may maintain continuous residence while abroad. Breaks in Continuous Residence: An absence of more than 6 months but less than 1 year creates a rebuttable presumption of a break; the applicant may overcome it by evidence that they did not disrupt residence (e.g., kept employment, family remained in U.S., retained a home). An absence of 1 year or more automatically breaks continuity unless the applicant has an approved Form N-470. Good Moral Character Edge Cases: Conduct outside the GMC period may still impact the determination. The catch-all provision in INA 101(f) means that even conduct not explicitly listed can preclude GMC if it offends accepted moral standards. USCIS may rely on local counsel in cases involving specific jurisdictional case law.
