For naturalization under the 5-year rule, you must have maintained continuous residence in the United States for the 5 years immediately preceding your N-400 application. An absence of 6 months or more (but less than 1 year) is presumed to have broken continuous residence, and an absence of 1 year or more creates a stronger presumption of abandonment. Rules change. Consult an immigration attorney or check uscis.gov for current guidance. This is educational information, not legal advice.
Continuous Residence Details
Continuous residence does not mean you must stay in the United States every day. Travel is permitted. What it requires is that your primary home and domicile remain in the U.S. throughout the period. USCIS considers whether you maintained a U.S. residence (lease or mortgage), filed U.S. tax returns as a resident, kept your family here, and showed other ties indicating your life remained centered in the United States. The pattern of your ties matters as much as the length of any individual trip.
The 6-month rule
A single continuous absence of 6 months or more (180 days or more) is presumed to interrupt continuous residence. That presumption can sometimes be rebutted by showing strong U.S. ties throughout the absence, but rebuttal requires evidence and is not guaranteed. If you have had an absence of this length, consult an immigration attorney before filing.
The 1-year rule
An absence of 1 continuous year or more generally breaks continuous residence and may also affect lawful permanent resident status. In limited cases, applicants can apply to USCIS to preserve residence for absences over 1 year. Certain employees of U.S. companies abroad and qualifying religious workers are among those who may be eligible. The requirements are strict, and the application typically must be filed before departure.
How this differs from physical presence
Continuous residence is about maintaining U.S. ties and not abandoning your domicile. One long trip can break it. Physical presence counts actual days inside the country and can fall short through many shorter trips. Both requirements must be met independently. See physical presence requirements for the day-counting rules.
Maintaining continuous residence during the required period
The continuous residence period is the 5 years (or 3 years) immediately before you file Form N-400. Time before that window does not count. If you have a gap within the period (say, 9 months abroad), you may need to wait until you have a clean 5-year span before filing. An immigration attorney can calculate your specific eligibility date.
