If you are age 50 or older and have lived in the U.S. as a green card holder (permanent resident) for at least 20 years, you can have the citizenship interview conducted in your native language.This is commonly referred to as the â50/20â waiver.hese 20 years of permanent residence do not need to have been continuous. If you have been outside the U.S. for short periods of time (fewer than six months at a stretch, to be safe), that is okay, so long as all your time living in the United States totals 20 years. The second rule is known as the â55/15â waiver.
