Trips abroad and continuous residence: the 6-month and 1-year rules

Naturalization looks at your time in the U.S. in two ways, and you must meet both:

• Continuous residence: you must have lived continuously in the U.S. as a permanent resident for the 5 years before filing (3 years on the marriage route), and keep living here until you take the oath. Long single trips are the danger.
• Physical presence: you must have been physically in the U.S. for at least 30 months of the 5 years before filing (18 months, or 548 days, of the 3 years on the marriage route). Every day abroad counts, including many short trips.

You also need 3 months of residence in the state or USCIS district where you file.

A single trip of 6 months or less does not by itself break continuous residence. But those days still count against physical presence, so add up every trip.

The N-400 asks for every trip outside the U.S. of more than 24 hours during the statutory period. Compare your list with your passport stamps and your I-94 travel history from U.S. Customs and Border Protection (i94.cbp.dhs.gov).

An absence of more than 180 days but less than 365 days is presumed to break continuous residence. You can rebut (overcome) the presumption with evidence, for example that:

• You did not end your U.S. job or take a job abroad.
• Your immediate family stayed in the U.S.
• You kept full access to your U.S. home, or continued to own or lease it.

Bring that evidence (employer letters, lease or mortgage, family records) to the interview. If you cannot rebut the presumption, you need a new statutory period. In a USCIS Policy Manual example, an applicant on the 5-year route who came back from an 8-month trip on August 1, 2018 could file again from February 1, 2023.

An absence of 365 days or more breaks continuous residence automatically, whether it happens before or after you file. USCIS must deny an N-400 in that situation unless you have an approved Form N-470.

After coming back from such a trip, the USCIS Policy Manual says the earliest you can file is:

• 5-year route: 4 years and 1 day after your return, but you will then have to rebut the 6-month presumption, because the period still includes more than 6 months of that trip. Waiting 4 years and 6 months after your return avoids the presumption.
• 3-year marriage route: 2 years and 1 day after your return (with the same rebuttal), or 2 years and 6 months to avoid it.

A reentry permit protects your green card during a long trip, but it does not preserve continuous residence for naturalization.

Form N-470, Application to Preserve Residence for Naturalization Purposes ($420), can protect continuous residence during long work abroad for:

• The U.S. government or a recognized American research institution.
• An American firm (or a subsidiary more than 50% American-owned) engaged in U.S. foreign trade and commerce.
• Certain public international organizations the U.S. belongs to.
• A religious denomination or mission organization, for religious work.

You must have been physically present in the U.S. as a permanent resident for an uninterrupted year before leaving, and you must file before you have been abroad for 1 continuous year. An approved N-470 does not count the time abroad as physical presence (except for U.S. government employees and certain religious workers), and it does not stop USCIS from finding that you abandoned your residence.

• Count your days abroad yourself; do not rely on memory.
• Remember that the time after filing counts too: a long trip while your N-400 is pending can make you ineligible.
• Plan travel around your biometrics, interview and oath appointments.
• If you have had any trip over 6 months, consider talking to an immigration attorney or DOJ-accredited representative before filing. USCIS decides each case on its own facts, and this guide is not legal advice.
