N-648 Mental-Health Evidence
N-648 Bipolar, Psychosis, or Severe Mood-Disorder Evidence
Severe bipolar disorder, psychosis, schizoaffective symptoms, or major mood episodes may affect memory, concentration, communication, judgment, and the ability to study or answer civics questions. USCIS will usually need a careful medical explanation that connects the condition and treatment history to the specific naturalization testing barrier.
Evidence should show functional impact
- Diagnosis and treatment history, including hospitalizations, crisis episodes, therapy, psychiatry, medication changes, and stability patterns.
- How symptoms or medication side effects affect memory, concentration, reading, speech, sleep, attendance, or reliable interview participation.
- Why the limitation is medically based and not only nervousness about the interview.
Records to organize before relying on N-648
- Psychiatry and therapy records, medication lists, hospitalization or emergency records, disability records, and current provider explanations.
- Family or caregiver statements describing daily functioning, appointment support, medication supervision, or relapse patterns.
- A timeline that distinguishes stable periods, flare-ups, and current functional limits.
Common consistency problems
- Make sure the N-648 explanation matches N-400 answers about work, school, arrests, treatment, address history, and interpreter/accommodation needs.
- If depression, anxiety, PTSD, sleep problems, or medication side effects overlap, explain how each fits into the same disability picture.
- Avoid broad statements like “cannot study” without examples showing what happens when the applicant tries to learn or answer.

Before you submit or attend the interview
Review the N-648 form, medical records, N-400 answers, interpreter or accommodation needs, and the interview plan together. The goal is a consistent packet that explains diagnosis, duration, treatment, and functional limits without overpromising results.
