USCIS Physical Presence Requirements Table

The table below outlines the statutory physical presence thresholds required by the USCIS depending on your naturalization filing path:

Filing Path Statutory Period Required Presence Max Allowed Absence
5-Year Rule (Standard) 60 Months (5 Years) 913 Days 912 Days
3-Year Rule (Spouse of U.S. Citizen) 36 Months (3 Years) 548 Days 547 Days

How USCIS Counts Your Travel Absences

When evaluating your application for naturalization, USCIS counts the number of days you were physically outside the United States. Only trips lasting 24 hours or longer are considered absences.

Furthermore, the day you depart and the day you return are considered to have been spent partly in the United States and do not count as absences. For example, if you leave on June 1 and return on June 3, you are considered to have been absent for exactly 1 day (June 2).

This uscis physical presence calculator helps you cross-reference your copy-pasted CBP I-94 logs against your planned filing date, automatically determining the exact days in your statutory window, separating valid dates from anomalies, and displaying a clean eligibility checklist.

Continuous Residence vs. Physical Presence

Meeting the physical presence requirement does not guarantee your continuous residence requirement is met. Continuous residence refers to maintaining the U.S. as your permanent home. Taking a single trip of 180 days or longer disrupts this continuity. You must ensure that you pass both checks before submitting your N-400 naturalization package.
