Upload your documents, then confirm every field
Snap your green card, passport, or past USCIS notices. Keystone Citizen suggests names, dates, and numbers from your uploads so you can confirm them and answer what's left. Always review every answer yourself before you file.
Reuse what you already entered
Upload a prior filing and your next form can start with matching fields pre-filled, for example when you move from a green-card packet to a citizenship form. You still review and update anything that changed.
Plain-language help, in your language
Ask what a question means in English, Spanish, and more. This is general information only, not legal advice, and it is not a substitute for an immigration attorney.
Consistency check before you print
Keystone Citizen compares your answers to your uploaded documents and flags possible mismatches (such as names or dates) for you to review. You decide what to change before printing or filing.
Free reprints after you file
If USCIS asks for more evidence, use Keystone Citizen to update your answers and reprint your pages at no extra cost. Keystone Citizen does not contact USCIS or appear for you.
Keystone Citizen is self-help form software, not a law firm, and not affiliated with USCIS. Using Keystone Citizen does not create an attorney-client relationship. AI and document extraction can be wrong; you are responsible for accuracy before filing. For advice about your case, consult a licensed immigration attorney.
