When this issue belongs in an N-648 review
USCIS reviews whether a medically determinable condition prevents the applicant from meeting the naturalization English or civics requirements. The safest approach is to organize diagnosis, treatment, duration, and functional-limit evidence before the interview or before responding to an RFE.
What the doctor should connect
- Diagnosis history, treatment plan, A1C or specialist records where relevant, and the expected duration of the condition.
- Complications such as neuropathy, retinopathy, kidney disease, severe fatigue, dizziness, pain, or hypoglycemia episodes.
- The exact testing functions affected: memory, concentration, reading, writing, speech, sitting tolerance, medication timing, or ability to follow interview questions.
Helpful supporting records
- Endocrinology, primary-care, nephrology, ophthalmology, podiatry, or neurology records when they explain complications.
- Medication lists, glucose logs, hospitalization records, therapy or mobility notes, and caregiver observations that match the medical record.
- Examples from daily life such as missed appointments, inability to study consistently, needing help with written tasks, or episodes that interrupt concentration.
Common weak spots
- A form that lists diabetes but never explains why English or civics testing is medically impossible.
- Old records that do not show current functional limits or medication side effects.
- Family statements that overstate disability or conflict with the doctor’s explanation.

Frequently asked questions
Can diabetes support Form N-648?
Sometimes, but USCIS usually needs more than the diagnosis. The medical professional should connect specific complications or treatment effects to the applicant’s English, civics, communication, memory, or interview functions.
Do neuropathy or vision problems matter?
They can matter if they affect reading, writing, mobility, sitting tolerance, daily functioning, or the ability to participate in testing. The form should explain the functional impact, not just list the complication.
Should glucose episodes or medication side effects be documented?
Often yes. Hypoglycemia, fatigue, dizziness, confusion, pain, or medication effects may explain inconsistent interview performance when they are documented and tied to the testing requirements.
