Intellectual or developmental disability
Severe traumatic brain injury or stroke sequelae

FAQ

N-648 questions, answered.

What is Form N-648?+

N-648 is a USCIS medical certification that requests an exception to the English language and/or civics requirements of naturalization based on a physical or developmental disability or mental impairment.

Who can complete Form N-648?+

A licensed medical doctor (M.D.), doctor of osteopathy (D.O.), or licensed clinical psychologist authorized to practice in the United States. We are experienced with USCIS N-648 requirements.

What should I bring to my N-648 appointment?+

Government-issued photo ID, your N-400 receipt or filing notice, all medical records related to your condition (specialist notes, imaging, neuropsychological testing), a list of current medications, and any prior denied N-648 forms if applicable.

How long is the N-648 valid?+

USCIS requires the N-648 to be signed by the certifying physician within 6 months prior to the date it is submitted with your N-400 or presented at your interview.

What if my condition doesn't fully prevent me from learning English?+

The impairment must be medically determinable and expected to last at least 12 months, and it must prevent you from demonstrating knowledge of English and/or civics. We'll review your records honestly to determine whether certification is clinically appropriate.

Is the form really sealed?+

Yes. USCIS requires the completed N-648 to arrive in a sealed envelope. Do not open it — a broken seal can lead to rejection.
