What Form N-648 is for

Completed by a licensed medical professional for naturalization applicants seeking English or civics test exceptions.

Medical Certification for Disability Exceptions (N-648) is generally filed by lawful permanent residents and others pursuing U.S. citizenship or citizenship documents. Whether this form fits your situation depends on your specific facts, so confirm the current eligibility rules on the official USCIS page before you file.

What Asal can help prepare

We help track medical certification requirements and how N-648 fits into your N-400 packet.

  • Prepare the form from the information you provide
  • Organize supporting documents
  • Coordinate certified translations when needed
  • Give you a clear filing checklist

What Asal cannot legally advise on

  • We do not provide legal advice or case strategy.
  • We do not represent you before USCIS.
  • We do not decide whether you qualify for a benefit.

If your case involves complex legal issues, consult a licensed immigration attorney.

N-648 document checklist

  • Medical records
  • N-400 application
  • Physician licensing info
  • Disability documentation

Your case may need additional documents. We give you a tailored checklist during a free document review.

Fees and official sources

USCIS filing fees change periodically and vary by category, age, and filing method. We do not quote government fees from memory. Always verify the current N-648 filing fee, payment method, and any form-specific fee rules on the official USCIS page before you submit.

Processing times for N-648 vary widely by service center, workload, and case complexity, and they change month to month. Check current estimates with the USCIS processing-times tool and your receipt notice rather than relying on a fixed number. Filing a complete, well-organized packet is the best way to avoid Requests for Evidence that add delay.

USCIS government fees are separate from Asal preparation fees. Verify current fees on USCIS.gov.
