Process and timing

Continuous residence and physical presence

Also called continuous residence, physical presence.

Continuous residence and physical presence are the two separate naturalization tests in 8 U.S.C. 1427(a): an unbroken five year residence in the United States after admission as a permanent resident, and at least 30 months, or 913 days, actually spent inside the country during those five years.

What it decides

They break in different ways, which is why they are counted separately. Under 8 U.S.C. 1427(b) an absence of more than six months but less than a year is presumed to break continuous residence and the presumption can be rebutted, while an absence of one year or more breaks it outright. USCIS then treats an applicant as eligible again either four years and six months after returning, which pushes the whole absence out of the five year window, or four years and one day after returning, which leaves an absence of more than six months inside the window and so still requires rebutting the presumption. The regulation, 8 CFR 316.5(c)(1)(ii), gives only the four years and one day figure. Physical presence is a pure day count, and USCIS counts both the day of departure and the day of return as days present. An approved Form N-470 preserves continuous residence during qualifying employment abroad, but 8 U.S.C. 1427(c) says it does not relieve the physical presence requirement except for people employed by or under contract with the US government.

Governed by 8 U.S.C. 1427(a), (b) and (c); 8 CFR 316.2(a)(3) for continuous residence and 316.2(a)(4) for the 30 months of physical presence; 8 CFR 316.5(c)(1)(i) and (ii); USCIS Policy Manual, Volume 12, Part D, Chapter 3, section C, Breaks in Continuous Residence, and Chapter 4, section A, Physical Presence, both showing current as of 5 August 2026. The four years and six months alternative and the 913 day figure appear in the Policy Manual only; the regulation gives four years and one day and the statute says only half the time.
