(MEXICANS ONLY PLEASE) When entering the U.S. Did you have to have anything other than your passport

Question

My fiance is coming back from MEXICO and she thinks that she needs her Mexican Identification card or license as we say in the U.S. Will she really need the Identification card or will the passport be sufficient enough.

Answer 1

She will need a visa which must be obtained at a US consulate or the embassy in DF

Answer 2

I guess she is mexican. We only need the american visa to cross the border, usually inmigration officers in USA don't even pay much attention to the mexican passport, but you need it too anyway.

Answer 3

i take it she is not a U.S. citizen if she has a MEXICAN ID.

so she will need her passport and a visa. she can get the visa at the port of entry for less than $20.

if she is a legal U.S. resident, then she only needs her green card.
