To request this exemption, it's essential that a duly authorized medical professional conducts an evaluation of the applicant.

Difference between Immigration Psychological Evaluation and Form N-648

It's important to understand that immigration psychological evaluation and Form N-648 are not the same. They are two distinct yet related elements in the immigration process in the United States.

Immigration Psychological Evaluation refers to the assessment of a person's mental and
emotional health by a professional, such as a clinical psychologist. This
evaluation is conducted to determine if a person has any mental disorder or psychological
disability that may affect their ability to adapt to life in the United States or meet
immigration requirements. This evaluation aims to provide a comprehensive picture of the applicant's mental health and is not specifically linked to obtaining an exemption from immigration requirements. Its results can be used for the diagnosis and treatment of
mental health issues, therapy, counseling, or any other purpose related to the individual's mental health.

In the case of Form N-648 (Medical Certification for Disability Exceptions), this is a specific document used in U.S. immigration processes. Its purpose is to allow naturalization applicants with a physical, developmental, or mental disability to apply for an exemption from certain medical or psychological requirements needed to obtain an immigrant visa or adjust their status to a permanent resident in the country. Form N-648 is intended for obtaining an exemption from immigration requirements and must be completed by an authorized medical professional. The results of a psychological evaluation can be used as part of the evidence to support an exemption request through Form N-648 if the applicant's
mental disability is one of the factors affecting their ability to meet immigration requirements.

What is the Reasonable Accommodation Request, and How Does it Differ from Form N-648 ?

It's essential to differentiate between Form N-648 and a reasonable accommodation request. When an applicant has difficulty learning or demonstrating knowledge due to a disability but is not incapable of doing so, they will not be granted an exemption from English and civic education requirements. Instead, the applicant may be eligible to receive a reasonable accommodation under the to meet these requirements.
However, this does not imply an exemption.

Form N-648 is only necessary for those applicants who, due to a physical, developmental, or mental disability, cannot meet the requirements of English and civic education exams.


Form N-648 and psychological evaluation are essential components of the immigration process in the United States for those facing mental health challenges or disabilities. The documentation and process are complex and should be handled by authorized medical professionals and experienced . It's important to stay informed about current requirements and regulations, as they may undergo certain variations over time. For up-to-date information, it is recommended to consult official USCIS sources or seek specialized legal support.
