Citizenship · 7 min read
One seven-month trip can matter more than twenty short ones.
Citizenship has two travel tests, and they measure different things. Most people only know about one of them.
The short version
- Physical presence: at least 913 days in the U.S. in the last 5 years (548 days in 3 years if married to a U.S. citizen).
- Continuous residence: no single trip that breaks it. Over 6 months raises a question. 1 year or more usually breaks it.
- You can file up to 90 days before your 5- or 3-year green card anniversary.
Two tests, two questions
Physical presence asks: how much time did you actually spend here? It’s a total. Every trip adds up.
Continuous residence asks: did you ever really leave? It looks at each trip on its own. Twenty one-week trips don’t threaten it. One long one can.
You need to pass both.
Marco’s five years
Marco got his green card in March 2021. He travels a lot for work and spent seven months in Italy caring for his mother in 2023.
- Days in the 5-year window
- 1,826
- Days abroad, all trips
- 540
- Days in the U.S.
- 1,286
- Physical presence · 913 needed
- Pass
- Longest trip · 212 days
- Review
Marco clears the 913-day bar with room to spare. But the Italy trip ran over six months, so USCIS will presume his continuous residence was broken unless he shows otherwise.
That presumption can be rebutted. Marco kept his job, his apartment and his car, and filed U.S. taxes as a resident. That’s the kind of evidence an officer looks for.
How long is too long?
Under 6 months
Doesn’t break continuous residence. Still counts against physical presence.
6 to 12 months
Presumed broken. You can rebut it with evidence of ties to the U.S.
1 year or more
Breaks it, unless you had an approved Form N-470 before you left.
Evidence that helps after a long trip
- You kept your U.S. job, or didn’t take a job abroad
- Your spouse or children stayed in the U.S.
- You kept your home, lease or mortgage here
- You filed U.S. tax returns as a resident
Mistakes we see most
- 01Listing trips from memory. The N-400 asks for every trip over 24 hours. Mismatches with CBP records slow interviews down.
- 02Forgetting land crossings. Drives to Canada or Mexico sometimes show up with no port, or not at all. Check your own records.
- 03Filing too early. The 90-day window is counted back from your anniversary. A day early can mean a denial and a lost fee.
- 04Assuming N-470 covers everything. It can preserve continuous residence for certain jobs abroad. It doesn’t add physical presence days.
