My dad’s a permanent resident of the US but he wants to travel to Mexico this year. Can he use a Mexican passport to go to Mexico and use it to come back? He has a US ID, US Driver’s license, a Mexican birth certificate, and a social security card.(he is taking a bus to Mexico)

To come back (whether by air or otherwise), he does not need a passport, but he does need an acceptable document to prove his permanent resident status. This is normally the green card. If he doesn't have a green card, he should apply for a new one as soon as possible.
