Various physical accommodations are also available for those with hearing, vision, or mobility impairments.

Westminster, home to the vibrant Little Saigon community, has many long-term permanent residents ready to become U.S. citizens. For those with medical conditions, disabilities, or advanced age that affect their ability to take the standard English and civics tests, USCIS offers accommodations and waivers. Whether you live near the Asian Garden Mall, the Westminster Civic Center, or the residential areas along Bolsa Avenue, understanding these options can make citizenship achievable for you or your loved ones.

Types of Citizenship Accommodations

USCIS offers three main types of accommodations for naturalization applicants who cannot meet standard testing requirements due to physical or mental conditions: the N-648 disability exception, age-based exemptions, and procedural accommodations.

Accommodation Type	Who Qualifies	What It Provides
N-648 Disability Exception	Physical or developmental disability affecting ability to learn	Waiver of English and/or civics test requirements
50/20 Age Exemption	50+ years old with 20+ years as permanent resident	Take civics test in native language
55/15 Age Exemption	55+ years old with 15+ years as permanent resident	Take civics test in native language
65/20 Special Consideration	65+ years old with 20+ years as permanent resident	Simplified civics test (20 questions) in native language
Physical Accommodations	Hearing, vision, mobility impairments	Sign language, wheelchair access, extended time, etc.

The N-648 Disability Exception

Form N-648, Medical Certification for Disability Exceptions, allows applicants with qualifying disabilities to be excused from the English and/or civics test requirements. A licensed medical professional must complete the form certifying the disability prevents the applicant from learning or demonstrating knowledge of English and civics.

•Must have physical or developmental disability or mental impairment
•Condition must be expected to last 12+ months
•Disability must directly affect ability to learn English/civics
•Licensed doctor, clinical psychologist, or osteopath must complete N-648
•Doctor must explain how disability prevents learning
•Form must be completed in English
•USCIS officer reviews and makes final determination
•May waive English only, civics only, or both

Qualifying Conditions for N-648

The N-648 is not available for everyone with a disability. The condition must specifically prevent the applicant from learning or demonstrating knowledge of English and civics, even with accommodations. Common qualifying conditions include:

•Alzheimer's disease and dementia
•Intellectual and developmental disabilities
•Traumatic brain injury with cognitive impairment
•Stroke with resulting cognitive deficits
•Severe psychiatric conditions (schizophrenia, severe depression)
•Post-traumatic stress disorder (PTSD) in severe cases
•Autism spectrum disorder affecting learning
•Multiple sclerosis with cognitive involvement
•Severe learning disabilities
•Combinations of conditions affecting cognitive function

How to Complete Form N-648

The N-648 must be completed by a licensed medical professional who has examined the applicant. The form requires detailed information about the disability and its impact on the applicant's ability to learn English and civics.

1
Schedule medical appointment
Find a licensed doctor, clinical psychologist, or osteopath willing to complete N-648
2
Bring your medical records
Provide documentation of your condition, treatment history, and any previous evaluations
3

7

Age-Based Exemptions (50/20, 55/15, 65/20)

Long-term permanent residents who are elderly may qualify for exemptions that allow them to take the civics test in their native language. These exemptions recognize that learning a new language becomes more difficult with age and that long-term residents have demonstrated commitment to the United States.

•50/20: 50 years old at filing + 20 years as permanent resident = civics in native language
•55/15: 55 years old at filing + 15 years as permanent resident = civics in native language
•65/20: 65 years old at filing + 20 years as permanent resident = simplified civics (20 questions) in native language
•Years as permanent resident calculated from green card issuance
•Can bring interpreter to interview for civics test
•Interpreter must be fluent in both English and native language
•Interpreter cannot be attorney or person appearing on application
•English test still required unless you have N-648

Physical Accommodations

Applicants with physical disabilities that don't prevent learning but affect their ability to participate in the interview can request procedural accommodations. These accommodations ensure equal access to the naturalization process.

•Sign language interpreter for deaf or hard of hearing applicants
•Wheelchair accessible interview rooms
•Extended interview time for those who need it
•Large print materials for vision impaired
•Off-site interviews if applicant cannot travel to USCIS office
•Assistance with oath ceremony participation
•Breaks during interview for medical needs
•Companion present for support (non-participating)

Common N-648 Denials and How to Avoid Them

Many N-648 applications are denied due to incomplete information or failure to establish how the disability prevents learning. Understanding common denial reasons helps applicants prepare stronger applications.

•Incomplete form: Every section must be filled out thoroughly
•Insufficient nexus: Must explain how disability prevents learning, not just that disability exists
•Old conditions only: Condition must be expected to last 12+ months from filing
•Normal aging: Simple aging without specific impairment doesn't qualify
•Lack of treatment: If treatable condition is untreated, may not qualify
•Inconsistencies: Information in N-648 should match N-400 and interview statements
•Doctor unfamiliar with form: Find provider experienced with N-648
•Literacy alone: Illiteracy in native language doesn't automatically qualify

What to Expect at the Interview

Applicants with N-648 or requesting accommodations should know what to expect at their naturalization interview. Being prepared helps the interview proceed smoothly.

•USCIS officer will review N-648 documentation
•Officer may ask questions about your condition and daily functioning
•Questions assess if disability prevents learning (not just that learning is difficult)
•If N-648 approved, skip English and/or civics test
•If N-648 denied, must take required tests that day or reschedule
•Applicants with interpreters will have civics test read in native language
•Accommodations (wheelchair, sign language) should be arranged in advance
•Bring identification and interview appointment notice as usual

Finding a Doctor for N-648

Not all medical providers are familiar with the N-648 form or comfortable completing immigration-related documentation. Finding the right provider is important for a successful application.

•Primary care physician who knows your history is often best choice
•Specialists (neurologist, psychiatrist, psychologist) for specific conditions
•Doctor must be licensed in U.S. (DC, state, or territory)
•Clinical psychologist licensed in U.S. can complete N-648
•Doctor should understand they're certifying inability to learn, not just disability
•Community health centers may help uninsured applicants
•Some immigration-focused medical practices specialize in N-648
•Get medical records from previous providers if changing doctors

Vietnamese Community Resources

Westminster's Little Saigon community has numerous resources for Vietnamese speakers navigating the naturalization process with accommodations. Many providers offer Vietnamese-language services.

•Vietnamese community centers: Citizenship class referrals
•Vietnamese-speaking doctors familiar with N-648
•Community legal services with Vietnamese staff
•Vietnamese interpreters for citizenship interviews
•Senior centers with citizenship assistance programs
•Vietnamese-language study materials for civics test
•Local nonprofits offering naturalization workshops
•Religious organizations providing citizenship support

FAQFrequently Asked Questions

Q:Does being elderly automatically qualify me for N-648?

A: No. Advanced age alone does not qualify for the N-648 disability exception. However, elderly applicants may qualify for age-based exemptions (50/20, 55/15, 65/20) that allow the civics test in their native language. If you have a medical condition in addition to your age that prevents learning, such as dementia, you may qualify for N-648. The exemption and waiver are different: exemptions require testing in native language, while N-648 waives testing entirely.

Q:Can I bring an interpreter to my citizenship interview?

A: If you qualify for the 50/20, 55/15, or 65/20 age exemption, you can bring an interpreter for the civics portion of your interview. The interpreter must be fluent in both English and your native language and cannot be your attorney or anyone who appears on your application. The interpreter must be at least 18 years old. If you have N-648 waiving the civics test, you won't need an interpreter for that portion.

Q:My parent has dementia - can they still become a citizen?

A: Possibly, depending on the severity. If dementia prevents your parent from learning English and civics, they may qualify for N-648 to waive those requirements. However, applicants must still be able to take the Oath of Allegiance and understand its meaning. In severe dementia cases where the applicant cannot understand the oath, naturalization may not be possible. Have their doctor complete N-648 and discuss the case with an immigration professional.

Q:What if my N-648 is denied at the interview?

A: If the USCIS officer denies your N-648 at the interview, you may be asked to take the English and/or civics tests that day. If you fail or cannot take the tests, your application may be continued (allowing you to return for testing) or denied. You can appeal a denial or file a new N-400 with an updated N-648 that better addresses the denial reasons. Consider consulting an immigration attorney if your N-648 was denied.

Q:How do I request a wheelchair accessible interview?

A: When you receive your interview appointment notice, contact the USCIS Contact Center at 1-800-375-5283 to request wheelchair accessibility or other physical accommodations. You can also note accommodation needs on your N-400 application. Make the request well before your interview date to ensure arrangements are made. USCIS offices are generally ADA compliant, but specific arrangements may be needed.

Q:Can learning disabilities qualify for N-648?

A: Severe learning disabilities may qualify for N-648 if they prevent the applicant from learning English and civics, even with accommodations and study. The key is demonstrating that the disability makes learning impossible, not just difficult. A psychoeducational evaluation documenting the learning disability and its impact on acquiring new knowledge can support the N-648 application.

Q:What happens at the oath ceremony if I have mobility issues?

A: USCIS makes accommodations for oath ceremonies. If you use a wheelchair, you don't need to stand. If you're unable to travel to a ceremony location, arrangements can sometimes be made for bedside or at-home ceremonies in exceptional circumstances. Contact USCIS after your interview approval to discuss specific accommodation needs for the oath ceremony.

Q:How long does the N-648 evaluation take?

A: The medical appointment for N-648 completion typically takes 30-60 minutes, depending on the complexity of your condition and whether the doctor has your medical records. The doctor may need additional time to complete the paperwork. Plan to have the N-648 completed at least several weeks before your interview. If you're filing a new N-400, you can include the N-648 with your application.
