Who commonly uses it. A permanent resident applying to become a U.S. citizen — usually after five years as a permanent resident, or three years if married to and living with a U.S. citizen.
Official form and instructions: USCIS — N-400. Clarenor is not affiliated with USCIS.

Documents you may need
- Front of your Permanent Resident Card Required
- Back of your Permanent Resident Card Required
- Two passport-style photographs Required
- Federal income tax returns for the last 5 years (or 3 if married to a U.S. citizen) Required
- IRS tax transcripts, if you have them (not required for everyone) — Transcripts are generally stronger evidence than a copy of the return.
- Marriage certificate (not required for everyone)
- Divorce decree or death certificate for any prior marriage (not required for everyone)
- Records for any dependent children (not required for everyone)
- Certified court records for any arrest or charge (not required for everyone) — A Case Guide will tell you exactly which records are needed.

- Travel records or passport stamps for the last 5 years (not required for everyone)
Documents are stored privately and are never publicly accessible. Only you and the Case Guide working on your case can open them, and you can replace or delete anything you upload.
How the process works
- Choose a package. You see exactly what each includes and what it does not before you pay.
- Answer the questions. Save at any point and return later.
- Upload your documents against the checklist.
- Pay. Payment is what places your case with a Case Guide. You are not charged before this step, and you pay the government fee separately to USCIS.
- A Case Guide reviews your case for completeness and consistency and tells you what is missing.
- You revise if asked, then a final readiness review completes the case.

Why this price. Five years of addresses, travel, employment and tax records, plus the good-moral-character questions. Review time is substantially longer.
USCIS filing fees are not included and are paid by you, directly to USCIS. Clarenor never collects a government fee on your behalf. Each package states its full refund terms on the service page.
What this service does not do
We do not decide whether you are eligible for naturalization, and we do not assess good moral character. Where your answers raise a legal question — any arrest or charge, a tax problem, a long absence, or an answer to the good-moral-character questions — we flag the case for a person to look at and tell you plainly that legal advice may be needed.
Clarenor does not file your application: you file it yourself. We do not represent you before USCIS and we do not provide legal advice.
