N-400 Citizenship Calculator | Visafig Official Figures
Five years after your green card — three if you’re married to a U.S. citizen — you can file Form N-400, and you’re allowed to file up to 90 days early. This n-400 citizenship calculator applies the INA §316 continuous-residence and physical-presence rules to your green-card date and travel history, then shows your earliest realistic filing window. The calculator does the subtraction so you don’t miss that 90-day head start.

Frequently Asked Questions
When can I apply for U.S. citizenship?
Generally you may file Form N-400 after 5 years as a lawful permanent resident (3 years if married to and living with a U.S. citizen), and you may file up to 90 days before that anniversary. You must also meet continuous-residence and physical-presence tests.
Does a trip abroad break my continuous residence?
A single trip over 6 months (180 days) raises a presumption that continuous residence was broken; a trip over 12 months generally breaks it and restarts the clock unless you can rebut it. Shorter trips are usually fine if you keep U.S. ties.
What is the physical-presence requirement?
You must be physically present in the U.S. for at least 30 months out of the 5 years (18 months if married to a U.S. citizen) right before filing. This calculator checks whether your reported time abroad keeps you above that threshold.
Is this the same as legal advice?
No. This is an educational estimator based on INA §316. Complex travel, tax, or criminal-history issues should be reviewed with a licensed immigration attorney.
