N-400 Helper
Fill out your N-400 with confidence.
Talk it through like a normal conversation, in English, Spanish or Portuguese, and N-400 Helper fills in the real USCIS N-400 from what you say. Prefer typing? That works too.

How it works
Grab your green card.
The app reads up to six answers off the front, and you check each one. You can skip this.
Talk it through.
Answer in your own words, in English, Spanish or Portuguese, or type if you'd rather.
Check your answers.
Every answer is listed in the order the form asks for it. Tap any one to fix it. Anything the form still needs shows under "Needs you."
Print it or save it.
Pay once per A-Number to print, share or save your filled-in N-400.
Sign it and file it.
Sign where the form asks and gather the documents USCIS lists for your case. Then file it the way USCIS's instructions say, by mail or, in some cases, online.
Just talk it through
No 14-page form on a tiny screen. Talk or type the way you would tell a friend, and the app puts each answer in the right place on the form, even when one reply covers several questions.
Start with your green card
Show the front of your card and the app reads up to six answers off it, like your A-Number and date of birth. You check each one before it's saved. You can skip this.
See every answer
Your answers list shows everything in the order the form asks for it. Tap anything to change it, free, as often as you like. Anything the form still needs is listed under "Needs you."
Stand-ins for your personal details
There's no account and nothing to sign up for. Your voice and your card photo stay on your iPhone. Before your words go to our server, the app looks for your personal details and swaps the ones it finds for stand-ins. The app asks first: its first screen, "Before we start," tells you what gets sent and that AI services from other companies read it. Nothing is sent until you tap "Agree and continue." How we handle your data.
Free to fill out
Filling out the form and previewing every page are free. You pay once per A-Number, only to print, share or save it. No subscription. You don't have to finish first. Tap "See the form so far," then "Get the printable form" whenever you're ready.
Tell a friend
Know someone else applying? Once your form is ready, you can share N-400 Helper from the app.
Who this is for
Permanent residents getting ready to apply for U.S. citizenship who want a clear, careful way to prepare Form N-400 themselves. Some answers may need an immigration attorney's help. The app tells you when, and links to USCIS's page on finding a lawyer or accredited representative.
An honest note
N-400 Helper is an independent app made by WEIRTECH. 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. N-400 Helper is not affiliated with, endorsed by, or connected to U.S. Citizenship and Immigration Services or any government agency. USCIS forms are always free. Filing fees are paid to the U.S. Department of Homeland Security, never to us.
