Keystone Citizen (Orvil Nunez, doing business as Keystone Citizen, "we") provides self-help software that helps you fill in USCIS Form N-400 yourself. We are not a law firm and do not give legal advice. Using the software does not create an attorney-client relationship.
We are not affiliated with, endorsed by, or acting for U.S. Citizenship and Immigration Services (USCIS), the Department of Homeland Security (DHS), or any government agency.
You choose every answer. You are responsible for making sure your answers are true, complete and current, and for checking the latest USCIS form edition and instructions.
You must review every page, sign and date by hand where required (we never sign for you), attach the required documents, pay any USCIS fee directly to USCIS, and mail or file the application yourself.
If your situation is complicated (for example arrests or citations, long trips abroad, tax problems, or prior immigration issues), talk to an immigration attorney or a DOJ-accredited representative before filing.
The questionnaire and the DRAFT preview are free. The preview is marked "DRAFT PREVIEW — NOT FOR FILING".
The final PDF is a one-time purchase shown with its price before you pay. Payment is processed by Stripe; we do not see or store your card number. The USCIS filing fee is not included and is paid separately to USCIS.
After payment, your browser builds the final PDF and answer worksheet on your device. Download access lasts 7 days from payment, with a limited number of downloads. Because answers are not stored on our servers, keep your own copies.
Refunds are covered by our Refund Policy. If a payment is refunded or disputed, download access ends.
Use the software only to prepare your own application. A family member or friend may help you use it, but you must choose and review every answer yourself. Using the software does not authorize anyone to represent you before USCIS. Do not misuse the site, try to bypass payment, or interfere with its security.
The chat assistant gives general information about the form and the process. It is not a lawyer, does not give legal advice, and can make mistakes. Do not type A-Numbers, Social Security numbers or case details into the chat. You still choose and review every answer yourself.
We work to keep the software accurate, but it is provided "as is". We do not guarantee that USCIS will accept your application, schedule an interview, or approve it. Outcomes depend on your facts and on USCIS.
To the extent the law allows, our total liability for any claim about the software is limited to the amount you paid us for it, and we are not liable for indirect or consequential losses (such as filing delays or fees paid to USCIS).
We may update these terms; the version and date below apply from when they are posted. These terms are governed by the laws of New York, United States, except where your local consumer law gives you more protection.
