Enter your green card date and your trips abroad. The calculator shows the earliest date you can file Form N-400, counts your physical presence days, and flags trips that may have broken continuous residence. It handles the 5-year rule and the 3-year rule for spouses of US citizens. When a rule has two readings, it uses the stricter one, so an early filing doesn't cost you the non-refundable fee. Your dates never leave your browser.
