Age-based exemptions: 50/20, 55/15 and 65/20

Your age and how long you have held a green card can change which tests you take — and in what language. Each rule below requires both numbers: your age when you file Form N-400, and your years as a lawful permanent resident. One alone is not enough. Not sure which rule applies to you? Use the checker — enter your numbers and get the answer directly.

The 50/20 rule

If you are 50 or older and have been a permanent resident for 20 years or more, you are exempt from the English test — reading, writing and speaking. You still take the civics test, but you may take it in the language of your choice, with an interpreter selected by you or by USCIS.

The 55/15 rule

If you are 55 or older and have been a permanent resident for 15 years or more, the same exemption applies: no English test, and the civics test in your own language with an interpreter selected by you or by USCIS.

The 65/20 rule: special consideration

If you are 65 or older with 20 years or more as a permanent resident, you get everything above plus special consideration on civics: USCIS administers specially selected test forms drawn from a short list of 20 designated questions, so that list is all you study. See the full list on our 65/20 page.

Medical disability: Form N-648

Separately from age, an applicant with a qualifying physical or developmental disability or mental impairment that prevents them from meeting the English and/or civics requirements may seek an exception with Form N-648, certified by a licensed medical professional. Read the full N-648 guide for who qualifies, what the form must show, and what happens at the interview.
