About

Fill out your N-400, the Application for Naturalization, just by talking. N-400 Helper talks with you about your life in plain words, like a normal conversation, and fills in the form from what you say. One reply can answer several questions, like saying your whole address at once. Answer out loud, or type if you'd rather. Your answers go into the real USCIS N-400, all 14 pages, every answer in the box where it belongs. Snap your green card. The app fills in up to six answers from the front of your card, like your A-Number and the date you became a resident. You check each one before it's saved. You can skip this and just talk. See every answer. One list, in the order the form asks for it, shows where each answer goes. Tap any answer to change it, free, as often as you like. Know what's left. Anything the form still needs shows up under "Needs you," so you can finish it before you print. Free to fill out. Filling out the form, looking through every page and changing your answers are free. You pay once, only if you want to print, share or save your filled-in N-400. One purchase covers the N-400 for one A-Number, and you can print it as often as you need. No subscription. Your privacy. Your personal information is locked on your iPhone, with its strongest protection. Your voice never leaves your phone: Apple's speech recognition turns it into text right on your iPhone, and the recording is never saved. Your green card photo is read on your phone and never uploaded. Before your words go to our server so the assistant can understand them, the app looks for your name and other personal details and swaps the ones it finds for stand-ins. Only your phone can put them back. Some answers, like your city, the dates of trips and jobs, and yes or no answers, are sent as they are. No account, no email, no password, and no tracking. "Delete all my data" in Settings erases everything the app has stored on your phone and what our server keeps for it. Use it in English, Spanish or Portuguese. When you're done, you print your N-400, sign it and file it yourself. The app shows you the next steps and links to USCIS's N-400 page. Please read: N-400 Helper is not affiliated with USCIS or any government agency. We are not a law firm, we do not give legal advice, and this app is not a substitute for the advice of an attorney.
