What Is Form N648?

The N648, or a Medical Certification for Disability Exceptions, is a disability waiver that exempts specific American citizenship candidates from proving that they can read, write, and speak English. The waiver allows applicants to interview in their native language and are awarded an exemption from answering questions about U.S. history and governance.

The US Citizenship and Immigration Services (CIS) considers the applicant’s doctor’s medical opinion and the specific facts about the applicant’s physical or developmental disability when determining whether or not to grant the waiver. During the naturalization interview, the USCIS officer decides whether to give or reject citizenship. 

Who Can Complete Form N648?

The only person who can complete Form N648 is the applicant’s medical doctor, doctor of osteopathy, or clinical psychologist. The medical professional must be authorized to operate in the United States. Additionally, they should be authorized in the Commonwealth of the Northern Mariana Islands, Puerto Rico, and the U.S. territories of Guam.

Additionally, the doctor completing Form N648 must have the skills, training, and experience needed to assess the said disability. If the physician lacks the said expertise, the applicant should consult a specialist to complete the form.

USCIS Checklist For Submitting Form N648

Once you submit Form N648 to the USCIS, an immigration officer starts reviewing the form, checking for its completeness. Here is a list of items they look for;

Is the Submitted Form the Right Edition?

Immigration forms are updated regularly. The new versions contain substantive changes that form part of the basis for Form N648 approval or denial. To get the updated version of Form N648, visit the USCIS official website.

Was Form N648 Submitted at the Same Time as Form N400?

According to the USCIS filing guidelines, the applicant should file Form N648 concurrently with  Form N400.

Has the Form Been Filled Out Completely?

The USCIS officer goes through the form to ensure the applicant’s medical professional answered all the questions and completed all sections.

They also check for all the signatures. If Form N648 does not contain all this information, the USCIS officer rejects the waiver request.

If a question does not apply to you, the doctor must fill the space with either “N/A” or none. Leaving one question unanswered can make your Form N648 marked as incomplete.

Is the Connection Clear?

The USCIS officer checks if the doctor made a clear connection between the applicant’s disability or impairment with his inability to read, write, speak English or learn U.S history and civics. The doctor should explain the relationship by providing enough information. Tackling the question with a one-sentence answer may force the officer to mark the form as incomplete.

The doctor should explain how the stated disability or impairment affects the applicant’s cognitive abilities. Additionally, they must explain how the applicant’s daily life is affected by the impairment or disability.

Does Form N648 Have Any Traces of Fraud?

The USCIS officer carefully scrutinizes the form to look for discrepancies, fraud, or misrepresentation. They also review the reasons for the request for a waiver of the citizenship exam to determine whether the doctor is truthful.

During the naturalization interview, the officer asks the applicant several questions. If his or her answers do not relate to those on Form N648, the USCIS officer finds reasonable doubt in the accuracy of the medical certification.

The officer also checks whether the doctor is under investigation for fraud in another disability waiver application. They also go through past medical information that the applicant could have submitted to see if the past and present medical documentation is consistent.


The officer determining if the applicant qualifies for Form N648 relies on the information provided by the doctor. They are not medical professionals whatsoever.

So, the doctor should provide complete information in a layman’s language while defining any medical terminology. They should also make it crystal clear for the officer to see why the applicant cannot take the citizenship exam.
