As of November 21, 2022, U.S. Citizenship and Immigration Services (USCIS) is accepting only the 8/19/22 edition of Form N-648, Medical Certification for Disability Exceptions. USCIS revised the form and removed several questions, including dates of diagnosis and when the disability or impairment began; description of severity of each disability or impairment; effects on the applicant’s daily life; and an explanation of the doctor-patient relationship. Also, telehealth medical examinations are now permitted for Form N-648, among other changes.
USCIS will accept a Form N-648 after a Form N-400 is filed but recommends that applicants submit both forms at the same time.
