What is continuous residence?

Continuous residence means living in the United States permanently as a lawful permanent resident, without taking trips abroad long enough to break the residency clock. Section 316(a) of the Immigration and Nationality Act (8 U.S.C. section 1427(a)) requires most naturalization applicants to maintain continuous residence in the United States for the entire five-year statutory period before filing (or three years for those qualifying under section 319(a) as the spouse of a U.S. citizen). Continuous residence is a different requirement from physical presence (which counts the actual days the applicant was inside the country) and from maintaining lawful permanent resident status (which an applicant can keep with shorter trips).

Three rules govern continuous residence. First, an absence from the United States of more than six months but less than one year creates a rebuttable presumption that continuous residence has been broken; the applicant can overcome the presumption with evidence (continuous employment in the U.S., U.S. tax returns filed, family remained in the U.S., U.S. home maintained, lack of foreign employment) but must affirmatively rebut the presumption at the interview. Second, an absence of one year or more automatically breaks continuous residence, even with evidence of intent to remain a permanent resident. After such a break, the applicant must accumulate a new continuous residence period: typically four years and one day for most applicants under section 316, or two years and one day for spouses of citizens under section 319, before they can file again.

Third, applicants on certain types of qualifying employment abroad (employees of the U.S. government, U.S. research institutions, U.S. corporations engaged in foreign trade, public international organizations, or religious organizations) may apply for Form N-470 (Application to Preserve Residence for Naturalization Purposes) to preserve continuous residence during long absences. The applicant must file Form N-470 before the cumulative absences reach one year, and they must have one year of unbroken physical presence after admission as a lawful permanent resident before they can apply. Continuous residence is verified at the interview through travel history reported on Form N-400 and through review of the applicant's passport entry and exit stamps.
