Form N-648 Evaluations by a Licensed Psychologist
United States Citizenship and Immigration Services (USCIS) only accepts an N-648 signed by a licensed physician (MD or DO) or a licensed clinical psychologist. A clinical social worker, marriage and family therapist or counselor license is not enough by itself. We provide that evaluation, by telehealth statewide. If a disability keeps you from learning English or civics for the citizenship exam, this is the evaluation the N-648 is based on. Santa Clarita and every California city.

An N-648 disability waiver evaluation is the medical certification an N-400 naturalization applicant files to request an exception to the English requirement, the civics requirement, or both, when a physical or developmental disability or mental impairment prevents the applicant from meeting them, even with accommodations; USCIS decides whether to grant it. Authorized by Immigration and Nationality Act (INA) section 312(b) and 8 C.F.R. 312.2(b). Only a licensed medical doctor (MD), doctor of osteopathic medicine (DO), or licensed clinical psychologist can sign the form; a licensed clinical social worker (LCSW) or licensed marriage and family therapist (LMFT) license alone is not enough. The evaluation explains how the impairment prevents meeting the requirements (the "nexus"). $1,500 flat fee, usual 5-7 business day turnaround. Related reading: the complete N-648 guide.
Do I need a psychological evaluation for Form N-648?
Form N-648 asks USCIS for an exception to the English and civics requirements for citizenship because of a disability (USCIS decides whether to grant it), and it has to be completed by a licensed medical doctor, doctor of osteopathy, or licensed clinical psychologist. Dr. Mantonya is a licensed clinical psychologist, so the evaluation and the completed form come from the same exam. Whether to file for the waiver is your decision with your attorney.
The flat fee is $1,500, with the report usually in 5 to 7 business days (all fees are on our pricing page). You, a family member, or your attorney can write to us in any language. Asking is free.
USCIS Has Tightened N-648 Review
USCIS policy now focuses review on the validity of medical certifications: the N-648 now generally has to be filed with the N-400, multiple N-648s can draw added review, and the nexus explanation has to be clear. We write to that guidance. For a deep dive on the policy itself, the qualifying conditions list, and how the age-based testing exemption is different from the disability waiver, see our N-648 disability waiver guide.
-
Insufficient nexus
A diagnosis on its own is not enough. The medical professional must explain how the disability or impairment prevents the person from meeting the English or civics requirement, in detail tailored to that person (USCIS Policy Manual, Vol. 12, Part E, Ch. 3). "Patient has PTSD" does not do that. A form that explains how measured attention and memory problems keep the person from retaining new vocabulary gives the officer something specific to evaluate.
-
Boilerplate language
USCIS expects the explanation to be "sufficiently detailed and tailored to the individual," and a form that omits required information or has material inconsistencies is insufficient. Every report has to read like it was written for one specific applicant.
-
Inconsistency with prior records
Prior records such as an I-693 medical exam that show no history of the condition now claimed are one of USCIS's listed reasons to doubt an N-648, though an officer may not find the burden unmet solely because the condition was not disclosed before. When discrepancies exist we name them and explain them.
What the N-648 Evaluation Includes
-
Full cognitive assessment
Cognitive screening and testing chosen for the specific qualifying condition. PTSD calls for one battery. Dementia, intellectual disability, traumatic brain injury, or a specific learning disability each call for different ones. We do not run the same template every time.
-
Specific nexus statement
The connection between the diagnosis and the inability to meet the English or civics requirement, written like a clinician, not a checklist. Not "patient has PTSD." Instead: "patient's PTSD produces concentration impairment and memory fragmentation that prevents retention of new English vocabulary, scoring in the 5th percentile on the relevant measure."
-
Duration and prognosis
The condition has lasted, or will last, 12 months or more. We document that, then explain the prognosis with the clinical reasoning behind it instead of just stating the conclusion.
-
I-693 consistency review
We review the prior I-693 findings and other records when there are any, and address a material discrepancy with the civil surgeon's findings in the report itself.
-
Professional interpreter for almost any language, available if needed
We arrange the interpreter so the applicant does not have to use a family member to talk through their disability.
-
Revisions included
USCIS guidance can change. Reasonable revisions within the scope of the evaluation are included, and the findings stay Dr. Mantonya's independent clinical opinion. No revision fee.
How does the evaluation process work?
Five steps. Refer the client and Dr. Mantonya handles the rest.
Attorney referral
Email or call with the qualifying condition, the prior I-693 if there is one, and the N-400 timeline.
Records review
Dr. Mantonya reads the file before the visit: medical records, the prior I-693, any existing treatment notes.
Clinical evaluation
Cognitive assessment and psychological testing chosen for the specific qualifying condition. Telehealth or in person.
Form N-648 Completed
The completed, individualized N-648, with the specific nexus statement and supporting documentation, usually lands in 5 to 7 business days.
Attorney review
Reasonable revisions within the scope of the evaluation are included. No revision fee.

N-648 Evaluation FAQ
Can my client's therapist or counselor complete the N-648?
Only if the therapist is also a licensed physician (MD or DO) or a licensed clinical psychologist; those are the professionals USCIS accepts for the N-648. An LCSW, LMFT or counselor license alone is not enough to sign this form. If your client's current provider is not a physician or psychologist, Dr. Mantonya can complete the N-648 evaluation.
What does USCIS policy ask for?
USCIS's current N-648 guidance focuses review on the validity of medical certifications. It requires the N-648 to be filed with the N-400 (with an exception for extenuating circumstances), said multiple N-648s may raise credibility concerns, reaffirmed that the nexus must be clearly explained, and listed credible reasons to doubt a form, such as prior medical records with no history of the condition. Every evaluation is individualized and addresses each of these criteria.
Does the evaluation need to be completed within a certain timeframe?
Yes. Usually the N-648 has to be certified within a set period before the naturalization application (N-400) is filed; a form submitted later because a condition began or worsened after filing is handled differently, and your attorney checks the current timing rule. Naturalization also requires proof of good moral character, which is a separate requirement from the disability waiver. The completed N-648 is usually delivered within about 5 to 7 business days after the evaluation, which leaves time to file within that window.
Who can certify N-648?
Only licensed medical doctors (MD), doctors of osteopathy (DO), and licensed clinical psychologists can sign Form N-648 (8 CFR 312.2(b)(2); USCIS Policy Manual Vol. 12, Part E, Chapter 3). An LCSW, LMFT or counselor license alone is not enough.
What kind of doctor fills the N-648?
A licensed MD, DO or clinical psychologist experienced in diagnosing the condition can complete the form. Dr. Mantonya is a licensed clinical psychologist (PSY28494) qualified to complete N-648 evaluations.
What medical conditions qualify for N-648 disability waiver?
Conditions that can support an N-648 include PTSD with cognitive impairment, major depressive disorder affecting concentration and memory, intellectual disability, major neurocognitive disorders (dementia, TBI), specific learning disorders, and severe anxiety disorders, when they prevent the applicant from meeting the English or civics requirement. A diagnosis alone is not enough: the form must explain how the condition causes that inability (the nexus), and USCIS decides.
Can a primary care physician sign Form N-648 instead of a psychologist?
Yes if the PCP is an MD or DO. Under 8 CFR 312.2(b)(2), only three types of professionals may sign Form N-648: medical doctors (MD), doctors of osteopathy (DO), and licensed clinical psychologists. A nurse practitioner, physician assistant, LCSW or LMFT license alone does not authorize signing, whatever the specialty. For cognitive or psychological disabilities, a psychologist's standardized testing and diagnostic interview are one way to document the impairment.
What if the applicant has multiple cognitive conditions?
The N-648 can document multiple qualifying conditions on a single form. The evaluation makes a primary DSM-5-TR diagnosis and notes any contributing co-morbidities. Each condition gets its own nexus paragraph that walks through how it specifically blocks English or civics learning. When conditions genuinely co-occur, each is documented accurately; the goal is an accurate clinical picture, not stacking diagnoses (USCIS may view multiple submissions with added scrutiny).
Is a fresh evaluation required if the applicant re-files Form N-400 after a denial?
It depends. A new N-400 needs an N-648 certified within the period USCIS allows before that filing, so a form certified for the earlier application may be too old to use; whether a new examination is needed depends on how recent the last one was, the applicant's current condition, and the reasons USCIS gave. We can provide an updated evaluation that builds on the prior assessment and addresses the deficiencies USCIS identified.
What is the difference between Form N-648 and the 50/20 or 65/20 age-based exemptions?
The N-648 disability waiver and the age-based exemptions are separate pathways with different rules. The age-based exemptions (commonly called 50/20, 55/15, and 65/20) waive the English requirement based solely on age plus years of lawful permanent residence: a 50-year-old with 20 years of permanent residence may take the civics test in their native language, a 55-year-old with 15 years gets the same accommodation, and a 65-year-old with 20 years receives both a simpler civics test and native-language administration. No medical documentation, no Form N-648 required. The N-648 disability waiver is a medical certification under 8 CFR 312.2(b)(2) that can support an exception to the English requirement, the civics requirement, or both, when a physical, developmental, or mental impairment prevents meeting them, regardless of age or years as a permanent resident. The age exemptions excuse English only (8 CFR 312.1(b)); the 65/20 group also gets special consideration on civics (INA 312(b)(3)). An applicant who also cannot meet the civics requirement because of a disability can still file an N-648 for civics, and an applicant who does not meet an age-and-residence exemption relies on the N-648 alone.
Can the N-648 be filed after the naturalization interview has already been scheduled?
Only in limited cases. USCIS Policy Manual Volume 12, Part E now requires the initial N-648 to be submitted with the Form N-400; USCIS may accept a later submission where the applicant shows extenuating circumstances, such as a disability that began or worsened after filing. Only a medical doctor (MD), doctor of osteopathic medicine (DO), or licensed clinical psychologist may sign the form; an LCSW or LMFT license alone is not enough. Usually the certification has to be dated within a set period before the N-400 is filed; how the timing works for a late submission is a question for your attorney.
Composite examples
Composite, illustrative examples, not real cases. Names and details are invented. Worth flagging up front: only a medical doctor, doctor of osteopathic medicine, or licensed clinical psychologist may sign Form N-648. A social worker, marriage and family therapist or counselor license alone is not enough.
Aurora, 71, Philippines
Major neurocognitive disorder. Montreal Cognitive Assessment came back at 14 of 30, and a family informant reported four years of progressive memory and executive decline. The Form N-648 covered the diagnosis, the duration past the twelve-month threshold, and the causal nexus to the English and civics requirements. What makes this example strong: it documents a medically determinable impairment, its duration, and the link between the impairment and the inability to meet the requirements.
Reza, 58, Iran
Post-traumatic stress disorder following reported torture and political imprisonment. PCL-5 at 64; PHQ-9 at 23. The challenge: Reza's English was fine in conversation. What makes this example strong: the clinical narrative explained why concentration deficits, hyperarousal, and avoidance could still prevent him from learning and demonstrating the material in a test setting.
