Who needs to submit this form?
Applicants for naturalization seeking an exception because of a physical/developmental disability or mental impairment should submit it when filing Form N-400.
→ Check if you are applying for naturalization and have one of these specific types of impairments.
When must the medical professional fill out Form N-648?
The form must be completed within 180 days before the submission of Form N-400 to USCIS.
→ Confirm the completion date on the form relative to your Form N-400 filing date.
What if I think my disability is valid, but it's just 'illiteracy'?
Illiteracy alone is not a valid reason to seek an exception from the English/civics requirements; the impairment must be more specific.
→ Check Part 3 of Form N-648 to ensure the impairment listed isn't just general illiteracy or advanced age.
Do I need this form if they offer me accommodations?
Yes, you must file Form N-648 even if an accommodation is offered, but only if you are unable to complete the requirements *even with* that accommodation.
→ Review the list of reasonable accommodations (e.g., extended time) and confirm your inability to pass them.
What kind of disability counts?
It must result from anatomical, physiological, or psychological abnormalities, which can be shown by medical techniques.
→ Ensure the condition listed in Part 3 is medically verifiable according to these three categories.
