The Naturalization Test: What You Need to Know

Typically, all the lawful permanent residents (green card holders) going through the process of naturalization must take the naturalization test. As an important part of the naturalization process, the applicants must demonstrate their knowledge of the English language, U.S. history, and U.S. government.

The Makeup of the Naturalization Test

Essentially, the naturalization test is a two-pronged assessment designed to evaluate your understanding of the English language, U.S. history, and U.S. government. Remember, it isn’t just about memorizing facts–it’s about gaining a deeper understanding of American culture.

English Language:

To become a U.S. citizen, you need to show that you can read, write, and speak simple English.


Applicants must display a basic understanding of U.S. history, the structure of the government, and its functions.

Exceptions to the Naturalization Test

Thankfully, there are several exceptions available based on applicants’ age, duration of stay in the U.S., and health conditions. 

Exception Description
Age Exceptions
☞ For permanent residents over 50 who have lived in the U.S. for at least 20 years, or those over 55 who have been permanent residents for at least 15 years, they may be exempted from the English language test. However, they must still sit for the civics test, which can be done in their native language with an interpreter if needed.
Medical Disability Waiver
☞ Individuals with a physical or developmental disability or mental impairment may be eligible for Medical Disability Waiver. This waiver applies to both the English and civics test.
Continuous Residence Exception
☞ If you're 65 or older and have been a permanent resident for at least 20 years when you file for naturalization, you'll be given special consideration regarding the civics requirement.

Medical Disability Waiver: An In-Depth Look

Designed to provide reasonable accommodations for individuals who cannot memorize or communicate due to disability, Congress has established the Medical Disability Waiver. This waiver allows qualified individuals to obtain U.S. citizenship, regardless of their disability. If the USCIS officer validates the waiver during the applicant’s interview, the applicant may proceed without having to pass the usual naturalization exam.

Who Qualifies for the Medical Disability Waiver?

Applicants with a physical disability or mental impairment that has lasted or is expected to persist for at least 12 months can request the Medical Disability Waiver.

What Does the Waiver Cover?

The Medical Disability Waiver exempts applicants from both the English language and Civics requirements. So, if your Medical Disability Waiver gets approved, you will not need to demonstrate knowledge of the English language and civics.

A Real-World Example

To illustrate how the Medical Disability Waiver works, let’s consider a hypothetical case. Mr. John Doe, a 45-year-old man suffering from severe Parkinson’s disease for the past five years, could qualify for the Medical Disability Exception. His neurologist has confirmed that his condition is expected to persist and deteriorate over the next few years, and the disease significantly affects his motor skills and speech. Therefore, due to his physical disability, Mr. Doe could potentially be exempted from the naturalization test.

How to Request a Medical Exemption?

Obtaining a medical exemption from the naturalization test involves a specific process that an applicant must follow. The process revolves around Form N-648, known as Medical Certification for Disability Exceptions.

Decoding Form N-648: Medical Certification for Disability Exceptions

Form N-648, or the Medical Certification for Disability Exceptions, plays a pivotal role in obtaining Medical Disability Waiver. This form serves as a proof that an applicant has a physical disability or mental impairment that makes it difficult for them to fulfill the naturalization test requirements.

Who Completes Form N-648?

Only licensed medical or psychiatric professionals can complete and execute Form N-648.  In fact, USCIS will not grant Medical Disability Waiver if Form Form N-648 is issued by anyone other than licensed medical or psychiatric professionals. This could be a licensed medical doctor, osteopath, or clinical psychologist. They are responsible for conducting the necessary evaluations to determine whether the applicant’s medical condition qualifies them for a disability exception.

Let’s revisit the hypothetical example of Mr. John Doe. Given his severe Parkinson’s disease, his neurologist could provide the Medical Certification. His neurologist would state that Mr. Doe’s condition is expected to worsen over the years, making it difficult for him to write or speak clearly. Therefore, Mr. Doe could be eligible for an exemption from the naturalization tests.

Timing Your Request: When to Apply for the Medical Disability Waiver?

Applicants should request the Medical Disability Waiver at the same time they submit their Application for Naturalization (Form N-400). This is done by including the completed Medical Certification for Disability Exceptions (Form N-648) with their application. By submitting these forms together, the USCIS can evaluate the request for the Medical Disability Exception while reviewing the applicant’s eligibility for naturalization.

Remember, it is essential that Form N-648 is filled out by a licensed professional. They will attest to your physical disability or mental impairment and certify that it prevents you from fulfilling the requirements of the naturalization test. Doing this at the time of application ensures that USCIS has all the necessary information to process your request appropriately and efficiently.

Embracing the Journey to U.S. Citizenship Despite Physical or Mental Impairment

In conclusion, the journey toward becoming a U.S. citizen may seem complex, but there are provisions to ensure everyone gets a fair shot. If you’re a person with a physical disability or mental impairment, don’t let this discourage you. Explore the options available, and you might find that the path to citizenship is more accessible than you think.
