Is an immigrant who is 80 years old take the American citizenship exam?

Yes, an immigrant who is 80 years old is required to take the American citizenship exam if they are applying for U.S. citizenship. However, there are certain accommodations for older applicants; those who are 65 years old or older and have been permanent residents for at least 20 years are eligible for a simplified version of the civics test. Additionally, they can often request to take the test in their native language.
