N400Tracker: Green Card

N400Tracker turns the two things that decide your naturalization timeline - time and travel - into one clear answer: when can I file? FILING DATE COUNTDOWN Enter your Permanent Resident date and choose the 5-year rule or the 3-year marriage rule. The app works out your earliest filing date, including the 90-day early filing window, and counts down to it. PHYSICAL PRESENCE Every trip you log is subtracted from your days inside the United States. You see the days you have, the days you still need, and exactly how much margin is left. CONTINUOUS RESIDENCE WARNINGS A trip of 180 days or more can break continuous residence. Trips approaching that line are flagged before they become a problem, not after. TRIP PLANNER Thinking about a long trip? Enter a departure date and a length and see the effect on your record before you book anything. CIVICS TEST PRACTICE Practice the official questions using the same stopping rules as the real interview. The app selects the 2008 or 2025 test automatically from your N-400 filing date. Study mode lets you browse the full official catalog at your own pace, with no score and no time limit. INTERVIEW CHECKLIST The documents to bring, grouped the way you will actually use them. SIX LANGUAGES English, Español, Português, Türkçe, हिन्दी and العربية. The civics questions themselves stay in official English, because most applicants take the interview in English. PRIVACY There is no account, no sign-up, and no server. Everything you enter stays on your iPhone. The app collects nothing about you and works completely offline. PREMIUM Practice exams, the eligibility calculator, and trip entry are free. A single one-time purchase - not a subscription - unlocks saved practice history, resumable exams, and permanent trip history. IMPORTANT N400Tracker is an informational tool. It is not legal advice and it is not affiliated with USCIS or any government agency. Civics answers can change after elections and appointments; verify current answers at uscis.gov/citizenship/testupdates. Confirm your eligibility with USCIS or a licensed immigration attorney.
