N-648 Medical Waiver
Evaluation in Florida
Applying for U.S. citizenship but unable to meet the English or civics requirements due to a medical condition? Dr. Nuñez is a licensed neuropsychologist who completes USCIS Form N-648 evaluations — fully in Spanish, no interpreter needed.
N-648 Waiver
What is USCIS Form N-648?
USCIS Form N-648 — the Medical Certification for Disability Exceptions — allows applicants for U.S. citizenship to request an exemption from the standard English language and civics test requirements when a medically determinable physical or developmental disability or mental impairment makes it impossible for them to meet those requirements.
The form must be completed and signed by a licensed physician or clinical psychologist who evaluates the applicant and certifies the medical basis for the exception. Dr. Dagmar E. Nuñez, Psy.D., is a licensed clinical psychologist in Florida (License #PY10720) with experience completing these evaluations and providing the comprehensive documentation USCIS requires.
Key differentiator: The evaluation is available fully in Spanish — the clinical interview, cognitive testing, and all interactions with Dr. Nuñez. No interpreter is required. For many Latin American families, this makes a meaningful difference in comfort, accuracy, and the quality of the evaluation.
Eligibility
Who may qualify for the N-648 waiver?
Cognitive Disorders
Applicants with Alzheimer’s disease, dementia, or other disorders that significantly impair memory, language, and learning capacity. Learn about memory evaluations →
Intellectual & Developmental Disabilities
Applicants with intellectual disabilities or developmental disorders — for example, Down syndrome or autism spectrum disorder — that substantially limit communication and learning.
Acquired Neurological Conditions
Significant memory loss or cognitive decline following stroke, traumatic brain injury (TBI), or serious illness that prevents the applicant from learning English or passing the civics test.
Severe Mental Health Conditions
Severe mental health conditions that substantially limit learning or communication and meet the USCIS threshold for a medically determinable impairment.
What You Receive
Everything USCIS requires
- Completed USCIS Form N-648 — signed and certified by Dr. Nuñez, a licensed clinical psychologist in Florida.
- Supporting written report — documenting the diagnosis and its direct impact on the applicant’s ability to learn English or pass the civics test, meeting USCIS documentation standards.
- Bilingual evaluation — the interview, cognitive testing, and all conversations conducted in Spanish if preferred. No interpreter needed, ever.
Important: USCIS does not guarantee approval of any N-648 waiver. The evaluation documents the medical basis for the exemption request — the final decision rests with USCIS. Begin the process as early as possible, as there may be wait times for appointments and for USCIS to process your application.
How it works
The N-648 evaluation
step by step
Clinical Interview
60–90 minutes
A thorough review of the applicant’s medical history, current functional limitations, and the condition that prevents meeting the naturalization requirements. A family member or caregiver is welcome and often helpful. Conducted in Spanish or English based on your preference.
Cognitive Testing
Varies by case
Standardized neuropsychological tests assess memory, language, executive functioning, and overall cognitive capacity. Testing is adapted to the applicant’s language preference and functional level. Relevant medical records are reviewed as part of the evaluation.
Report & N-648 Completion
7–10 days
Dr. Nuñez prepares the written clinical report and completes USCIS Form N-648, signing and certifying the documentation to meet USCIS requirements.
Delivery & Next Steps
Guidance included
You receive the completed Form N-648 and supporting report. Dr. Nuñez’s team can answer follow-up questions about the documentation as you move through the naturalization process.
Start early — USCIS processing timelines mean the sooner you have documentation, the better.

N-648 Medical Waiver Evaluation
USCIS Form N-648 is the Medical Certification for Disability Exceptions. It must be completed by a licensed physician or clinical psychologist to certify that a medically determinable physical or developmental disability or mental impairment prevents a naturalization applicant from meeting the standard English language and civics requirements. Dr. Nuñez is a licensed clinical psychologist in Florida (License #PY10720) who is qualified to complete this form.
Applicants who may qualify include those with Alzheimer’s disease, dementia, or other cognitive disorders; intellectual disabilities or developmental disorders such as Down syndrome or autism spectrum disorder; significant memory loss or cognitive decline following stroke, traumatic brain injury (TBI), or serious illness; and severe mental health conditions that substantially limit learning or communication.
Yes. The evaluation — including the clinical interview, cognitive testing, and all conversations with Dr. Nuñez — is available fully in Spanish. No interpreter is needed. This is one of the key advantages of working with Dr. Nuñez for your N-648 evaluation.
No. USCIS does not guarantee approval of any N-648 waiver. The evaluation documents the medical basis for the exemption request — the final decision rests with USCIS. Dr. Nuñez provides thorough, USCIS-compliant documentation designed to support the strongest possible case, but the outcome is determined by USCIS.
Bring any available documentation of the condition: physician reports, neurologist records, hospital discharge summaries, prior psychological or neuropsychological evaluations, brain scans (MRI, CT), and a list of current medications. A family member or caregiver who knows the applicant well is also very helpful to have present during the interview.
