Understand Form N-648: Purpose and Importance
The naturalization process for individuals with physical or other disabilities can present challenges not faced by other potential citizens. One of the primary tools disabled individuals use to assert their right to test exceptions to English and civics testing for naturalization is the Medical Certification for Disability Exceptions (Form N-648). The Medical Certification for Disability Exceptions is important as it can facilitate individuals with disabilities’ becoming citizens in a fair manner and enable individuals with disabilities to become citizens in a manner that is respectful to their individual medical situations and are expressed in the most adequate language and manner.
Form N-648 together with completed application and supporting documentation are used to establish an individual’s eligibility for grant of an exception to requirements of citizenship testing. Recently USCIS updated the Guidance For Officers Adjudicating Medical Certification For Disability Exceptions To Requirements For Citizenship Testing (Form N-648) And Supporting Documentation. Significantly this updated Guidance makes it clear that when determining whether an individual qualifies for a disability exception to the requirements of citizenship testing for naturalization (English and civics testing), officers are to consider the Medical Certification for Disability Exceptions completed by the individual’s medical provider as well as all supporting documentation provided by applicant.
The medical documentation completed by an applicant’s medical provider may well fail to include all required diagnostic codes but in such situations the clinical diagnosis of the applicant’s condition is adequate to establish the basis for application of the disability exceptions to citizenship testing for naturalization. Furthermore, pursuant to the recently-revised USCIS policy Guidance, there is now greater flexibility with respect to the required signatures on the completed Medical Certification for Disability Exceptions (Form N-648). For example, where an individual applicant (or the authorized interpreter) is unable to sign the completed Medical Certification for Disability Exceptions (Form N-648) before it is submitted to USCIS (e.g. because the naturalization test(s) for which the applicant seeks waiver(s) of are to be administered at the same time as the naturalization interview during which applicant’s ability to take the test(s) are considered), then the applicant (or the applicant’s authorized interpreter) can sign the completed application during the naturalization interview in which the test(s) for which the applicant seeks waiver(s) of are considered.
USCIS reported that more than 818,500 naturalization candidates became new U.S. citizens in 2024. Many of these naturalization candidates utilized Form N-648 to address their individual medical circumstances or needs through the naturalization process. Updated Guidance increases transparency by clearly explaining the process and criteria for approval of disability exceptions to citizenship testing for naturalization by immigration officers as well as applicants. This revised Guidance also addresses a number of particular issues, including treatment of discrepancies in completed Medical Certification for Disability Exceptions (Form N-648) applications.
Overall, the recently-revised Guidance for Officers Adjudicating Medical Certification For Disability Exceptions To Requirements For Citizenship Testing (Form N-648) And Supporting Documentation simplifies and clarifies process of declaring oneself disabled for purposes of declaring oneself eligible for disability exceptions to citizenship testing for naturalization and demonstrates respect to individuals with disabilities seeking to utilize the U.S. immigration system in a manner which is both fair and is respectful to their individual circumstances. The Medical Certification for Disability Exceptions is an important component to the process of disabled individuals’ becoming U.S. citizens in a respectful manner and in a manner which is commensurate with the values of respect, fairness and dignity that the U.S. immigration system is supposed to embody.
