If you're 50 or older and have held a green card for at least 20 years (or 55 with 15 years), you can skip the English test on your naturalization application - but you still take the civics test, in your own language. If you're 65 or older with 20+ years as a permanent resident, you also get to study a much smaller set of civics questions. Separately, if a documented disability or impairment - not just old age - keeps you from learning English or civics, a doctor or clinical psychologist can complete Form N-648, Medical Certification for Disability Exceptions, which can excuse you from one or both tests. These are three different, sometimes overlapping, paths, and this article walks through each one.
The age-and-residence English exemptions: "50/20" and "55/15"
Most naturalization applicants must pass an English speaking, reading, and writing test as part of the N-400 process. USCIS makes two long-standing exceptions based on a combination of age and time spent as a lawful permanent resident (LPR):
"50/20" rule: You are age 50 or older at the time you file Form N-400 and you have been a lawful permanent resident for at least 20 years.
"55/15" rule: You are age 55 or older at the time you file and you have been a lawful permanent resident for at least 15 years.
If you meet either combination, you are exempt from the English requirement. You may answer the officer's questions and take the civics test in the language you are most comfortable with, using an interpreter. Under current USCIS guidance, if you bring your own interpreter, that person generally must meet basic requirements (such as being fluent in both English and your language) - check the current Form N-400 instructions or ask USCIS whether an interpreter will be provided at your interview.
Important: the 50/20 and 55/15 rules exempt you from English only. You must still demonstrate knowledge of U.S. history and government on the civics test, just not in English.
The "65/20" special consideration: a shorter civics test
A related but separate rule applies to older, long-term residents: if you are age 65 or older at the time of filing and have been a lawful permanent resident for at least 20 years, you get "special consideration" on the civics test. Instead of studying the full civics question pool, you only need to study a specially designated, smaller subset of questions (marked in USCIS study materials). At the interview, the officer asks a set number of questions from that shorter list, and you need to answer enough of them correctly to pass.
Applicants who qualify for 65/20 are also exempt from the English requirement and may take the civics test in their own language, just like under 50/20 and 55/15. Because USCIS periodically updates its civics test questions and study materials, always download the current version of the civics questions and the current 65/20 study list directly from uscis.gov rather than relying on an old printout or a non-official website.
These age/residence rules are separate from - and do not require - any showing of disability. They are based purely on your age and years as a green card holder.
The N-648 medical disability exception
If a medical condition, not just age, prevents you from learning or demonstrating English and/or civics knowledge, you may request an exception using Form N-648, Medical Certification for Disability Exceptions. This can excuse you from the English test, the civics test, or both, regardless of your age or how long you've held a green card.
Who qualifies
Per USCIS policy, to qualify you must have a medically determinable physical or developmental disability or mental impairment that has lasted, or is expected to last, at least 12 months, and that impairment must be the reason you cannot meet the English and/or civics requirements. USCIS is explicit on one point that trips people up: advanced age and illiteracy, by themselves, are not valid grounds for an N-648 exception. The medical professional must explain, in medical terms, how the specific disability or impairment - not simply the applicant's age or lack of schooling - prevents the applicant from learning or demonstrating the required English or civics knowledge.
Who can complete the form
Only a licensed medical doctor (M.D.), doctor of osteopathic medicine (D.O.), or a licensed clinical psychologist authorized to practice in the United States may complete and certify Form N-648. The professional generally must evaluate you (in person, or by real-time telehealth where state law permits). A general statement from a family member, a non-clinical counselor, or an unlicensed practitioner will not satisfy the requirement.
Timing
USCIS generally will not consider a Form N-648 if the certifying medical professional certified it more than 180 days before you file Form N-400. Plan your medical evaluation accordingly so the certification stays current when your application is submitted. Once that requirement is met, the certification generally remains valid for the rest of the naturalization process tied to that N-400.
How USCIS reviews it
USCIS reviews each N-648 for completeness, internal consistency, and credibility, and has increased scrutiny in recent years to identify and prevent fraudulent submissions. An officer may still ask you limited questions at your interview even with an approved N-648, and may follow up with the certifying professional if something is unclear. Because standards and the form itself are updated periodically, always use the current edition of Form N-648 and its instructions from uscis.gov, and confirm with USCIS or an accredited representative whether any recent changes affect your case.
What to do - step by step
Check your age and years as a permanent resident. Calculate this as of the date you plan to file Form N-400. If you meet 50/20 or 55/15, note that you plan to claim the English exemption on your application.
Check whether you also qualify for 65/20. If you're 65+ with 20+ years as an LPR, request the current 65/20 study materials from USCIS so you study the smaller question set instead of the full pool.
If a disability or impairment is the real barrier, see a qualifying medical professional. Only an M.D., D.O., or licensed clinical psychologist can complete Form N-648. Bring your immigration and medical history so the professional can document the connection between your specific condition and your inability to meet the English/civics requirements.
Get the current Form N-648 directly from uscis.gov and have it certified within the 180-day window before you file Form N-400.
File Form N-400 with the exemption claimed or the N-648 attached, following the current form instructions for how to indicate your basis for exemption.
Prepare for your interview accordingly - arrange an interpreter if you are using an age-based exemption and taking the civics test in your own language, and bring any documentation USCIS requests to support your N-648.
Consult a qualified immigration attorney or a Department of Justice (DOJ)-accredited representative if your situation is complicated - for example, if you're not sure whether your condition meets the N-648 standard, or you have a mixed case (partial disability plus age-based factors).
How this connects to the underlying citizenship test requirement
These exemptions and the medical waiver only modify the standard English and civics testing that applies to naturalization applicants generally. If you don't qualify for any of these exceptions, you'll need to prepare for and pass the regular naturalization civics and English test as part of your N-400 case. Reviewing what that standard test covers can help you understand exactly what these exemptions are excusing you from.
Beware of notario and immigration-consultant fraud
Because the N-648 medical waiver depends on precise medical and legal documentation, and because USCIS scrutinizes these forms for fraud, this is an area where bad advice or dishonest "help" can seriously damage your case - including allegations of misrepresentation. Never pay a "notario público," immigration consultant, or unlicensed preparer to fill out or "guarantee" an N-648 approval; in the United States, a notario is not a lawyer and has no authority to practice immigration law. Get help only from a licensed immigration attorney or a representative accredited by the Department of Justice's Office of Legal Access Programs, and get your medical documentation only from the qualifying licensed medical professionals described above.

Frequently asked questions
Do I still have to take the civics test if I qualify for the 50/20 or 55/15 English exemption?
Yes. The 50/20 and 55/15 rules only excuse the English test. You still take the civics test, but you may take it in the language of your choice with an interpreter. Check the current Form N-400 instructions on uscis.gov for whether you must bring your own interpreter and any requirements that interpreter must meet.
What is the difference between the 65/20 special consideration and the N-648 medical waiver?
The 65/20 rule is based only on age (65+) and time as a permanent resident (20+ years); it lets you skip English and study a smaller pool of civics questions, but does not require any disability. The N-648 waiver is based on a documented disability or impairment and can excuse both tests entirely, regardless of age.
Can old age by itself qualify someone for the N-648 medical waiver?
No. USCIS policy is explicit that advanced age and illiteracy alone are not valid grounds for an N-648 exception. There must be a medically determinable physical or developmental disability or mental impairment expected to last at least 12 months that actually prevents the person from learning or demonstrating English or civics knowledge.
Who is allowed to fill out Form N-648?
Only a medical doctor (M.D.), doctor of osteopathic medicine (D.O.), or a licensed clinical psychologist authorized to practice in the United States may complete and certify Form N-648. It generally cannot be certified more than 180 days before you file Form N-400.
Where can I find the current N-648 form and the civics questions list?
Always download the current Form N-648 and its instructions, plus the current civics study materials, directly from uscis.gov rather than relying on a third-party copy, since USCIS periodically updates form editions and study materials.
