N-648, Medical Certification for Disability Exceptions

The test for citizenship includes an English language proficiency portion as well as a United States civics portion. If an applicant is impaired by a disability, physical or mental, that would prevent him or her from successfully completing either of these portions of the test they may seek an exception from it.  To seek said exception the applicant should file form N-648, Medical Certification for Disability.

Form N-648 should submitted at the same time as filing form N-400, Application for Naturalization.

This form must be certified by a medical doctor, doctor of osteopathy, or a clinical psychologist licensed to practice in the United States.

The following information must be provided when filing this form:

  • The clinical diagnosis of the disability that impairs the applicant from successfully completing the English language and/or civics test;
  • A basic description of the disability;
  • The cause of the disability;
  • The clinical methods of diagnosis; and
  • A detailed description of how the disability will affect the applicant’s success during the English language and/or civics test.
