A Diagnosis Alone Doesn’t Waive the Test — the Nexus Does
Form N-648 can excuse an eligible naturalization applicant from the English and civics requirements, but only when a licensed medical professional documents a direct link between the disability and the inability to meet them.
USCIS tightened its review of every N-648 in June 2025, and now expects the form filed with Form N-400 rather than after it.

Why This Exemption Exists — and Why It’s Harder to Win in 2026
Congress built a narrow safety valve into the naturalization test requirements for applicants with disabilities.
Section 312(b)(1) of the Immigration and Nationality Act excuses the English and civics requirements for anyone unable to meet them “because of a medically determinable physical or developmental disability or mental impairment.”
USCIS carries out that exemption through Form N-648, Medical Certification for Disability Exceptions, filed together with Form N-400.
Two regulations control it: 8 CFR 312.1(b)(3) for the English exemption and 8 CFR 312.2(b) for the civics exemption.
Both regulations set the same threshold: the disability must have lasted, or be expected to last, at least 12 months.
A diagnosis is only the starting point. USCIS grants the exemption only when the applicant shows, by a preponderance of the evidence, a direct connection between the disability and the inability to learn or demonstrate English or civics knowledge — even with reasonable accommodations, according to USCIS’s Policy Manual guidance on Form N-648.
That standard got harder to satisfy in 2025. On June 13, 2025, USCIS updated its N-648 guidance to sharpen fraud screening and to treat any N-648 filed after the N-400 as presumptively late.
A late filing is now accepted only for narrowly defined “extenuating circumstances” — meaning the condition changed, worsened, or first appeared after the N-400 was already submitted.
There is no separate USCIS filing fee for the N-648 itself; the cost applicants bear is the medical professional’s evaluation, which is a private fee that varies by provider and is paid outside the naturalization filing fee.

A REAL CASE
A Second Chance After a Rushed First Filing
A woman in her seventies came to me after her naturalization interview had already gone wrong.
She had survived a serious stroke years earlier, and her family assumed a general letter from her primary doctor would excuse the English test.
The officer found that first N-648 insufficient — it described the stroke but never explained why it stopped her from learning English or civics.
She failed both tests at that interview, and USCIS scheduled her re-examination for roughly ten weeks later.
I arranged a full evaluation with a clinical psychologist, and the corrected N-648 tied her cognitive deficits directly to her ability to learn and retain new material.
She was granted the exemption at the second interview.
What to Do Before You File
THE PATH FORWARD
An Exemption Built on Evidence, Not on a Diagnosis
The N-648 process rewards preparation and penalizes shortcuts.
An experienced immigration attorney can help you time the filing correctly, select an evaluator who understands what USCIS is looking for, and anticipate the questions an officer will ask at the interview.
If you are also weighing other naturalization requirements — for example, how a past conviction affects your eligibility timeline or how the three-year marriage-based rule applies to your case — those issues should be reviewed alongside your N-648 strategy, not separately.
