Answer simple questions; I explain each one with the official instructions. At the end you download the official PDF filled in, to review, sign by hand and mail, or you follow the guide to file it online.
What to have at hand
- Your green card (A-Number and "Resident since" date).
- Your Social Security card, if you want an updated card when you become a citizen.
- Your addresses, jobs and schools of the last 5 years (3 if you apply as the spouse of a citizen), with dates.
- The dates of your trips outside the U.S. in that period.
- Your marriage details and those of your children under 18, and any arrest, citation or court record.
Your privacy
- Your answers stay in this browser. They are not sent to GreenBro.
- Nothing is saved unless you choose to: then it is encrypted with a password only you know, on your device, and deleted after 30 days without use.
- We only count, anonymously, how many PDFs are generated.
Form, instructions and edition: uscis.gov/n-400.
GreenBro is a free self-help tool. It is not a law firm, an immigration consultant or a "notario", and it is not affiliated with USCIS. It does not give legal advice: you are responsible for your answers and must review the form before signing it. The official instructions, edition and fees published by USCIS prevail. If your situation is delicate, talk to an attorney or an accredited representative: find legal services (USCIS). Your answers never leave your device.
