When you seek a medical certification for disability exception because of a physical or developmental disability or mental impairment that prevents you from learning English and civics, please keep in mind the following:
- There is no filing fee for Form N-648. However, a medical professional may charge a fee for a medical examination and for filling out forms.
- Only a medical doctor, doctor of osteopathy, or clinical psychologist licensed to practice in the United States may certify Form N-648. You may contact your state medical board to determine whether the medical professional has a valid license.
- An authorized medical professional must evaluate you in person or where the state law permits, a real-time telehealth examination, and diagnose you with a condition that prevents you from completing the educational requirements in order to qualify for the N-648.
- Read and sign the Applicant’s (Patient’s) Attestation/Release of Information. A legal guardian, surrogate, or designated representative, may also sign for an applicant who is unable to undergo any part of the naturalization examination because of a physical or developmental disability or mental impairment
