Can I apply for U.S. citizenship yet?
Answer a few questions and we'll estimate your eligibility and your earliest filing date for Form N-400. Nothing you enter leaves your device.
What is the 90-day early filing rule?
USCIS lets you file Form N-400 up to 90 days before you meet the continuous-residence requirement (5 years, or 3 years if married to a U.S. citizen). This checker subtracts 90 days to estimate your earliest filing date.
Does this checker decide my case?
No. This is an educational estimate based on the most common requirements. Many situations (military service, time abroad, good moral character, exceptions) change eligibility. Always confirm with USCIS or an immigration attorney.
