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)

    Is the US ID a green card? If not, does he have one? If not, is there anything preventing him from getting one before his trip?

  • Traveling by bus does not change that he needs proof of being allowed back into the USA, does he have a Green Card?

and use it to come back

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.

  • "he does not need a passport" - so the airline would accept a green card without a passport? (genuine question)

    This is ONLY correct if entering the US by land. If entering via air he will absolutely need a passport (Mexico passport is fine). As the question asked hasn't mention a means of transport, this answer is at best misleading!

  • @Midavalo if they follow TIMATIC, yes.

  • @Doc actually I believe green card is enough to travel by air, at least from US perspective (they may need a valid passport to exit the country though).

    @Doc: "If entering via air he will absolutely need a passport" Not as far as the US government is concerned. CBP's carrier information guide, page 32, says "A Lawful Permanent Resident may travel to the United States without a passport with a Permanent Resident Card (Form I-551)." Of course, just because the US government allow airlines to do it, doesn't mean the airline has to allow it.
