The way I understand it the way our laws are at the present time, is that if they step one foot on out soil, we can't just turn them around, by law they then get to have a hearing, and since they can't detain all of them, they turn them loose with instructions to check in, Yea right. lol
The Obama regime even bussed them to cities far from the border by the thousands to make the job for immigration as hard as possible.
I do not know when these laws got to the point to where they somehow have the right to have a hearing, when I was working around them and living in border states, they would round them up one day and they were back in Mexico the next.
