I have known Mexicans that lied about their immigration status,. They weren't on death's door, not being persecuted or starving. Actually they were just taking advantage of the lax immigration laws. It's a human thing. They left and went back to Mexico of their own free will but then they came back and they left again. They weren't bothered by the bugaboos of immigration law. Hell, even one burned down hers cousins van because he had her deported and her kid was taken away from her and placed in protective custody....please, Mexicans are full of surprises. But rarely are they the desperate refugees they make them selves out to be.
