Informational, not legal advice

N648Decoder.us is an educational website. The information on the Site — including the civics test version decoder, the N-648 eligibility checker, the rule explanations, and the question banks — is for general information only. It is not legal advice and does not create an attorney-client relationship.

We are not a law firm

We are not a law firm. We are not a USCIS-recognized organization. We do not employ licensed immigration attorneys or USCIS-accredited representatives to represent applicants. We do not file forms on your behalf. We do not provide individualized legal advice on your USCIS case.

Unauthorized practice of law (UPL)

Acting as a representative in USCIS proceedings without (a) being a licensed U.S. attorney in good standing, or (b) being a fully accredited representative on the DOJ EOIR Roster of Accredited Representatives, is the unauthorized practice of law (UPL). UPL is unlawful in every U.S. state. We do not engage in UPL and we strongly advise you not to retain anyone who is not a licensed attorney or a fully accredited DOJ EOIR representative for legal advice on your case.

To verify a USCIS-accredited representative, see the DOJ EOIR Recognition & Accreditation Program.

Only USCIS issues the decision

Only USCIS makes the final determination on your N-400 Application for Naturalization or Form N-648 Medical Certification for Disability Exceptions. No website, service, attorney, or representative can change USCIS's decision. We never claim otherwise.

Verify before acting

USCIS rules change. Before taking action — filing a form, scheduling an interview, contacting an attorney — verify current rules at uscis.gov. If a rule on this Site differs from uscis.gov, uscis.gov is the source of truth.
