Not sure if I've posted this in the correct area, couldn't find the immigration area...but my son who is in the Army recently married a young girl who is not legal, I believe she has her green card, but not sure....we will be traveling from California to Texas to see my son off to Iraq, and we will be bringing my new daughter in law back with us, would anyone happen to know if there are any checkpoints along the way from Texas to California? Thanks!
