Complete Guide to N-648

Updated on April 10, 2024

At a Glance

  • Form N-648 is a medical certificate used in the US naturalization process.
  • It allows applicants to claim disability exemptions from English language and civics tests.
  • Eligibility requires a permanent or long-lasting disability hindering learning English or US history.
  • The form is completed by a medical professional and submitted with the N-400 application to the local USCIS office.

People who have a disability and who are looking to gain citizenship from the United States of America have an option to apply for a waiver that exempts specific individuals from going through the same process of obtaining citizenship as other healthy and sound individuals. That is, if an applicant has any medically diagnosable disability, they can file form N-648 in light of their disability. 

What Is the Disability Waiver or Form N-648?

Form N–648 is a medical certificate to claim disability exemptions for the process of naturalization in the United States. The applicants who file form N–648 do not need to prove that they can read/write in English or understand it.

They can also claim exemption from taking the normally mandatory test on U.S. history and civics. It is given in stages depending on the applicant’s disability. That is, someone might only be exempt from the English requirements while others might get to take the test in their primary language or skip it altogether.

Am I Eligible for Form N-648?

Any person with any disability can qualify to file form N-648. However, three basic requirements are needed in order to be eligible:

  • The person has a physical and/or developmental disability or impairment.
  • The condition of disability is either diagnosed to be permanent or has lasted for the past 12 months or is expected to last for the next 12 months.
  • The impairment/disability makes it difficult for the person to learn English or U.S. history and civics.

Who Is Not Eligible to File Form N-648?

Applicants that have a disability but can still learn English and civics should not submit form N-648. As long as the applicant can still attempt to meet their requirements of learning English and passing the U.S. history and civics test, it is advised that they not submit form N-648. Typically, illiteracy and old age are not grounds to obtain an exemption.

How to Complete Form N-648

Completing form N-648 involves several steps:

  • Either type or write in black ink and fill out everything on the form.
  • Answer all questions fully and accurately to the best of your knowledge. And do not leave any field blank. If any question does not apply to you, either type/write “NA.”
  • Form N-648 is typically completed by a medical professional. They are required to explain your disability in as simple terms as possible and submit the form on your behalf. A medical professional will do the following items to complete your form N-648.
  • Identify and describe any and every diagnosis the applicant may have.
  • Explain how they, as a medical professional, reached their conclusions regarding the diagnosis of the anatomical, physiological, or psychological impairment, including citing any medically acceptable clinical and laboratory tests.
  • Specifically describe the severity of each medical disability and how it affects the applicant’s ability to function in daily life and their ability to learn ordinary English and/or U.S. history and civics.
  • Finally, if an interpreter is used to fill out the form, all contact details of the interpreter must be included in the form when asked.

Where to File Form N-648

Form N-648 should be mailed to the local United States Citizenship and Immigration office, where you have already submitted your form N-400, or it can be mailed along with it.

Fees for Form N-648

The filing fee for form N-648 is completely free at the United States Citizenship and Immigration office. However, the applicant does have to bear the costs of postage fees and the medical professional’s attestation charges, if any, or any other costs that may arise in association with the filing of the form.
