USCIS N-400 Naturalization & Continuous Residence Tracker
Log every trip outside the US and watch your physical-presence tally, longest absence, and earliest N-400 filing date update live. Pick your route — the 5-year permanent resident route needs 913 days in the US, the 3-year marriage route needs 548.
Key rule:
an absence of 180+ days at a time can break the continuous-residence presumption and reset your clock. The 90-day early-filing window lets you submit Form N-400 up to 90 days before your qualifying period ends.
