Medical Certification for Disability Exceptions (Form N-648)

Naturalization applicants with a physical or developmental disability may seek a waiver of the English and U.S. History and Government testing requirement. This waiver form (Form N-648) is completed by a medical doctor, a doctor of osteopathy, or a licensed psychologist. The evaluation process consists of a clinical interview with the psychologist and cognitive testing, if appropriate. Often speaking with other family members may also be required to complete the evaluation. If the client meets the criteria for an exemption, Form N-648 will be completed. Additional supporting documents may also be included.
