Do long trips outside the US break continuous residence for US citizenship?

Checked on 2026-10-25

Key facts

Absences between six months and a year

The law (8 U.S.C. 1427(b)) says an absence of more than six months but less than one year breaks continuous residence, unless you establish that you did not in fact abandon your US residence. This applies to the period before you file and also to the time between filing and your interview.

The regulation (8 CFR 316.5(c)(1)(i)) lists evidence that can show you kept your residence during the absence:

• you did not end your US employment;
• your immediate family stayed in the US;
• you kept full access to your US home;
• you did not take a job abroad.

The USCIS N-400 checklist asks applicants with trips of more than six months but less than a year for evidence such as rent or mortgage statements or pay statements, bank and credit card statements with regular transactions, car registration and insurance, passport stamps, and IRS tax transcripts.

Absences of a year or more

An absence of one continuous year or more breaks continuous residence (8 U.S.C. 1427(b)). The regulation then sets when you can apply again: four years and one day after you return to resume permanent residence if you need five years, or two years and one day if you are on the three-year route for spouses of US citizens (8 CFR 316.5(c)(1)(ii)).

Form N-470: keeping residence while working abroad

The law allows an exception for permanent residents who have been physically present and residing in the US for at least one uninterrupted year after getting the green card, and then work abroad for the US government, a recognised American research institution, an American firm (or its majority-owned subsidiary) engaged in developing US foreign trade and commerce, or a public international organisation of which the US is a member and which hired you only after you became a permanent resident. You apply on Form N-470 before you have been absent for a continuous year. An approval also covers your spouse and dependent unmarried children living abroad with you as part of your household (8 CFR 316.5(d)(1)(ii)).

N-470 protects continuous residence only. You still need the physical presence time (half of the residence period) unless you work for or under contract with the US government (8 U.S.C. 1427(c)).

Taxes count too

8 CFR 316.5(c)(2) says that if you voluntarily claim nonresident alien status to get special income tax exemptions, or don’t file federal or state income tax returns because you consider yourself a nonresident, there is a rebuttable presumption that you have given up the privileges of permanent resident status.
