Your Mexican Passport, nor Student ID give you legal status in the U.S. While Customs officials and BCBP are usually at points of entry from international flights, they are sometimes scattered across the U.S. in different places. There is always the possibility one will question you and you will then most likely be placed into deportation/removal proceedings. It would be best not to fly. Also, it would be best to try to work on getting an employer to sponsor you at this point or trying to regularize your status through family. Please see more below.

you are not in status. there is a huge risk that you will be questioned and even detained. that said, i am sure that thousands of undocumented people still get on a plane every day. i would say that the general rule is that you will have to show your passport without the visa. then if you lie about your status, you are in BIG trouble, but if you tell them about your status, you are leaving your life in their hands.
