Instructions
Read these instructions carefully to properly complete this form. If you need more space to complete an answer, use a separate
sheet of paper. Write the applicant's name and Alien Registration Number (A-Number), at the top of each sheet of paper and
indicate the part and number of the item to which the answer refers. You must sign and date each continuation sheet.

What Is the Purpose of This Form?

Who Is Authorized to Certify This Form?

In general, applicants for naturalization must demonstrate an
understanding of the English language, including an ability to
read, write, and speak words in ordinary usage. They must
also demonstrate a knowledge and understanding of the
fundamentals of the history and principles and form of
government of the United States. Together, these are known as
the English and civics requirements for naturalization. This
form is intended for applicants who seek an exception to the
English and/or civics requirements due to a physical or
developmental disability or mental impairment that has lasted,
or is expected to last, 12 months or more.

Only medical doctors, doctors of osteopathy, or clinical
psychologists licensed to practice in the United States
(including the U.S. territories of CNMI, Guam, Puerto Rico,
and the Virgin Islands) are authorized to certify the form.
While staff of the medical practice associated with the
medical professional certifying the form may assist in its
completion, the medical professional is responsible for the
accuracy of the form's content.

Who Should Submit This Form and When?
An applicant for naturalization seeking an exception to the
English and/or civics requirements for naturalization because
of a physical or developmental disability or mental
impairment(s) should submit this form at the time he or she
files an N-400, Application for Naturalization, with USCIS.
Per Immigration and Nationality Act (INA) 312(b)(1),
applicants are not required to fulfill the English and/or civics
requirements if the person is unable to do so because of
physical or developmental disability or mental impairment(s).
NOTE: Failure to submit Form N-648 with Form N-400
may delay the time for the adjudication of Form N-400.

Who Should Not Submit This Form?
An applicant who can satisfy the English and civics
requirements for naturalization with reasonable
accommodations provided under the Rehabilitation Act of
1973 does not need to submit this form. Reasonable
accommodations include, but are not limited to, sign language
interpreters, extended time for testing and off-site testing. An
applicant requesting an accommodation should so indicate on
Part 3 of his or her completed Form N-400. Illiteracy alone is
not a valid reason to seek an exception to the English and
civics requirement by submitting this form.

How to Complete This Form?
All parts of Form N-648 except the "Applicant Attestation"
and "INTERPRETER'S CERTIFICATION", must be certified
by a licensed medical professional. Before certifying Form
N-648, the medical professional must have conducted an inperson examination of the applicant.
All questions or items must be answered fully and accurately.
USCIS will not accept an incomplete Form N-648. Responses
should use common terminology, without abbreviations, that a
person without medical training can understand. If completed
in writing, all responses must be legible and appear in blue or
black ink. USCIS recommends that the certifying medical
professional use the electronic Form N-648 located in the
"FORMS" section at www.uscis.gov.
Failure to provide all information requested on the form may
result in USCIS determination that the form is insufficient. In
addition to providing a detailed assessment of the applicant's
physical or developmental disability or mental impairment as
requested on the form, a medical professional completing the
form may attach supporting medical diagnostic reports or
records. However, these attachments may not take the place of
written responses to each question or item on Form N-648.
The following are examples of sufficient responses to some of
the items on Part III of Form N-648:

Form N-648 Instructions (Rev. 06/17/11) N

1. Provide the clinical diagnosis and DSM IV code (if
applicable) of the applicant's disability and/or
impairment(s) that form the basis for seeking an
exception to the English and/or civics requirements.
If you cannot provide a DSM IV code, write "N/A" and
explain why you cannot provide a DSM IV code.
"DSM-IV 318.0 Down syndrome."
2. Provide a basic description of the disability and/or
impairment(s).
"Down syndrome is a genetic disorder that causes lifelong
intellectual disability (also referred to as mental
retardation), developmental delays, and other problems."
8. What caused the applicant's medical disability and/or
impairment(s) listed in number 1?
"Down syndrome is usually caused by an error in cell
division occurring in utero. The cause of such errors in cell
division is currently unknown."
9. What clinical methods did you use to diagnose the
applicant's medical disability and/or impairment(s)
listed in number 1?
"The patient was diagnosed in utero through a Chorionic
Villus Sampling (CVS). CVS is a test done during early
pregnancy that can identify certain genetic disorders or
chromosomal birth defects, such as Down syndrome."
10. Clearly describe how the applicant's disability and/or
impairment(s), affect his or her ability to demonstrate a
knowledge and understanding of English and/or civics.
"The patient's condition is a global, lifelong impairment
that severely affects cognition, language, and motor skills.
While many individuals with mild to moderate forms of
Down syndrome are capable of daily tasks and working in
the community, this patient suffers from a particularly
severe form. Because of this impairment, his memory is
deficient, he cannot learn new skills, and he is not capable
of reasoning but only of performing simple daily activities.
The patient's severe intellectual disability (mental
retardation) makes him incapable of learning a new
language (even basic words) and demonstrating the
required knowledge of U.S. history and government."

Whoever knowingly makes under oath, or as permitted under
penalty of perjury under Section 1746 of Title 28, United
States Code, knowingly subscribes as true, any false statement
with respect to a material fact in any application, affidavit, or
other document required by the immigration laws or
regulations prescribed thereunder, or knowingly presents any
such application, affidavit, or other document containing any
such false statement, shall be fined in accordance with this
title or imprisoned not more than 10 years, or both.
If either the applicant or the medical professional includes in
this form any information that the party knows to be false, that
person may be liable for criminal prosecution under U.S. laws.
In addition to the criminal penalties under Title 18 of the
United States Code, Section 274C of the Immigration and
Nationality Act and 8 U.S.C. 1324c provides for civil
penalties.
