Citizenship Physical Presence Calculator
without the guesswork.
Us Citizenship Naturalization Presence Calculator — Compare a complete N-400 physical-presence total with the selected USCIS route while keeping continuous residence separate. Uses a focused calculator with visible assumptions. Inputs stay in your browser.
This check compares the complete N-400 physical-presence total with the selected USCIS threshold. It does not convert that result into overall naturalization eligibility.
Context matters.
- USCIS treats the day of departure and the day of return as days physically present in the United States.
- An absence longer than six months can disrupt continuous residence; an absence of one year or more is a separate major issue unless a specific exception applies.
- The three-year spouse route has its own marital-union and citizenship conditions. Selecting it here does not establish those facts.

What to know before using the result.
Are departure and return days U.S. physical-presence days?
Yes. USCIS N-400 instructions count the day you leave and the day you return as days present in the United States.
Is 913 days enough to prove naturalization eligibility?
No. It is the physical-presence threshold for the general five-year route. Continuous residence, district residence, good moral character, English/civics and other requirements remain separate.
Does 90-day early filing lower the physical-presence requirement?
No. Early filing can affect when an application is submitted, but the required physical-presence days must still be met at filing.
