Understanding USCIS Form N-648: Medical Disability Waivers for Naturalization

The naturalization exam is a critical step for legal residents seeking U.S. citizenship. It tests proficiency in English and knowledge of U.S. history and government. However, for many individuals, passing this exam is not possible due to medical challenges.
To address this, USCIS Form N-648 provides a pathway for applicants with qualifying disabilities to request an exemption. According to the USCIS Policy Manual:
U.S. law provides an exception for applicants who are unable to meet the required proficiency in English or civics for naturalization because of a physical disability, developmental disability, or mental impairment.
This ensures that individuals with legitimate and documented disabilities are not excluded from the naturalization process.
WHY FORM N-648 IS CHALLENGING
Writing Form N-648 is not straightforward. USCIS officers review these forms carefully, often with skepticism, to ensure that applicants are not avoiding their responsibility to learn the required material. As a result, the form must be written in clear, accessible language that explains the applicant’s medical condition and how it prevents them from meeting exam requirements.
Disabilities vary widely, including:
- Age-related cognitive decline
- Head trauma or intellectual disability
- Mental health conditions such as PTSD, depression, or schizophrenia
- Side effects of medications or treatments (e.g., chemotherapy-related cognitive impairment)
Each case requires careful documentation and explanation in layman’s terms so that non-medical officers can understand the diagnosis and approve the waiver.
Our Approach
We specialize in preparing N-648 forms that meet USCIS standards. Over time, we have developed strategies to anticipate and address the kinds of objections officers often raise. For example, if an officer questions how someone struggling with cognitive impairment could still learn to drive, we explain the difference between a driving test and the naturalization exam.
In Minnesota, our track record allows us to guarantee acceptance of properly prepared forms. For applicants in other states, we continue working with officers and clients until the forms are accepted—without charging extra fees. When necessary, we collaborate with attorneys or even elected officials to ensure USCIS officers follow their own regulations.
Serving Patients In and Out of State
We have successfully handled hundreds of cases in Minnesota and assisted immigrants from states such as New York, Virginia, Illinois, California, Iowa, the Dakotas and others.
Because our medical licenses are limited to Minnesota, out-of-state applicants have two options:
- Virtual collaboration with a local doctor – We review the case virtuqally and provide guidance so the local physician can complete the form.
- In-person evaluation in Minnesota – Patients travel to Minnesota, where we can directly diagnose and sign the form.
Both approaches have proven effective, and we provide letters to out-of-state doctors explaining the process.
Case Examples
- Elderly Russian woman: With multiple chronic conditions (diabetes, hypertension, high cholesterol), she struggled to learn new information. After reviewing her medical history, we diagnosed cerebrovascular disease and explained how it impaired her cognitive function.
- Young Somali man: A survivor of war trauma and head injury, with no formal education, he suffered from PTSD and cognitive impairment. We documented how these factors prevented him from meeting exam requirements.
While these cases may seem obvious, USCIS officers often raise unexpected objections. Our role is to anticipate these challenges, explain medical realities in plain language, and ensure fair treatment under the law.
Conclusion
Form N-648 is a vital safeguard for immigrants with disabilities, ensuring they are not excluded from citizenship due to medical limitations. Preparing the form requires expertise, persistence, and a deep understanding of both medical conditions and USCIS procedures.
Through careful documentation and advocacy, we help applicants overcome barriers and achieve their goal of becoming U.S. citizens.
