Want a real person to help with your case?
Naturalization decisions are stressful. If you'd rather have a USCIS-accredited representative or licensed immigration attorney walk you through your N-400 or N-648, here are pro-bono and low-cost options. We are not affiliated with any of these organizations and we receive no payment when you contact them.
- DOJ EOIR Recognized Organizations Roster — find a USCIS-accredited representative at a DOJ-recognized organization in your area. Often free or low-cost; many are nonprofit community organizations.
- DOJ EOIR Recognition & Accreditation Program — official explanation of how the DOJ EOIR program works and how to verify accreditation.
- ImmigrationAdvocates.org Legal Directory — searchable nonprofit immigration legal-services directory.
N648Decoder is informational only and is not a law firm or USCIS-recognized organization. We do not provide legal advice and we do not receive payment from USCIS. Verify any organization's accreditation directly on the DOJ EOIR roster before relying on it.
One clear path forward.
The naturalization test can feel like a maze of versions and exceptions, but the rules are knowable. We show which civics test your filing date triggers, the exact question bank to study, and whether the senior 65/20 or N-648 medical waiver fits your case — each answer pinned to its USCIS or eCFR source. No account, nothing logged.
