Please read the instructions before examining the applicant and filling out this form.
In general, applicants for naturalization must demonstrate that they understand the English language, including the ability to read,
write, and speak words in ordinary usage. They must also demonstrate knowledge and understanding of the fundamentals of the
history, principles, and form of government of the United States. These are called the “English and civics requirements.” This form is
used for applicants to seek an exception to the English and civics requirements due to a physical or developmental disability or mental
impairment that has lasted, or is expected to last, 12 months or more. Applicants seeking such an exception should submit this form as
an attachment to the Form N-400, Application for Naturalization.
Please note:
Only medical doctors, doctors of osteopathy, or clinical psychologists can certify the form.
Additionally, they must be licensed to practice in the United States (including the U.S. territories of the Commonwealth of the
Northern Mariana Islands, Guam, Puerto Rico, and the Virgin Islands) to certify the form.
While staff of the medical practice associated with the certifying medical professional certifying the form may assist in its
completion, the certifying medical professional is responsible for the accuracy of the form's content and therefore must sign it.
Answer all the questions regarding medical information, using common terminology that a person without medical training can
understand, with no abbreviations. Failure to fully and accurately complete this form, including all applicable signatures, may
result in the form being found insufficient.
