Rule guide
US naturalization: physical presence
Physical presence and continuous residence are separate US naturalization requirements. Under the general INA 316 basis, an applicant usually needs at least 30 months of physical presence during the five years before filing; qualifying spouses applying under INA 319(a) generally need 18 months during three years. Other bases and exceptions can change the period or requirement.
Two requirements, two reviews
Physical presence measures time actually in the United States. Continuous residence addresses whether residence was maintained across the statutory period and can be affected by absences under separate rules. Meeting the day minimum does not by itself establish continuous residence.
Use the correct statutory basis
USCIS sets different periods for the general five-year route and the three-year spouse-of-a-US-citizen route. Qualifying employment abroad, certain family circumstances and military provisions may modify or remove requirements, so identify the filing basis before choosing a counter.
- Count the departure and return days as US physical-presence days under USCIS policy.
- Keep every trip outside the United States available for review.
- Check Chapter 5 and basis-specific policy before applying a general threshold.
Fictional example
Example only: Jordan plans to file under the general five-year basis and has 920 recorded US days. That may exceed the general physical-presence minimum, but Jordan still reviews continuous residence, the timing of every absence, jurisdiction and all other eligibility requirements.
