How the count works
The general route counts 913 days in the US in 5 years. The spouse route counts 548 days in 3 years. Days before permanent residence do not count.
- Both departure and return days count in the US; only whole days outside are subtracted.
- The green card anniversary minus 90 days sets the early filing floor. Physical presence and other clocks may push the date later.
- Trips of more than 180 whole days outside can affect continuous residence. A trip of 365 whole days or more resets its clock.
- After a reset, the general route waits 4 years and 1 day from return; the spouse route waits 2 years and 1 day.
- The spouse clock starts at the latest of permanent residence, marriage and the spouse becoming a US citizen.
- For Still away, the count assumes a return tomorrow. Planned trips are included.
Example: Jordan has a green card dated 15 Sep 2021 and checks 4 Oct 2026 on the general route. The example’s trips begin on 1 Apr 2022, 10 Jan 2023, 1 Sep 2023, 1 May 2024 and 1 Mar 2025. With their return dates entered, the count is 981 days in the US: the day requirements are reached on 4 Oct 2026.
Questions
How do I calculate physical presence for naturalization?
Start with your days in the US after your green card date, in the 5 years before the date to check. You need 913 days for the general route, or 548 days in 3 years for the spouse route. Enter every trip; departure and return days count in the US.
What is the N-400 90-day early filing rule?
You can start with your green card anniversary and count back 90 calendar days. Physical presence, any continuity reset and the spouse clock still have to reach their dates. Your result shows when the form can arrive, using those day requirements.
How many days can I be outside the US before applying for citizenship?
The count needs 913 days in the US in 5 years, or 548 days in 3 years for the spouse route. Long trips can affect continuous residence even when the physical presence count is high enough. Trips of more than 180 whole days are highlighted. Check the long-trip notes alongside your day total.
Do the days I leave and come back count?
Yes — the day you leave and the day you come back both count in the US. A trip from Friday to Sunday takes away one day, Saturday. Same-day and overnight trips take away no whole days.
What changes if I'm married to a US citizen?
The spouse route counts 548 days in 3 years. The clock date is the latest of your green card, marriage and spouse citizenship dates. Its full 3 years must pass; the 90-day early filing offset applies to the green card anniversary.
Is anything I enter saved or sent?
