That's just as easy. We handle them by SELF DEPORTATION. Simple. Make it hard for them to get the jobs, the schooling, the health care, etc. and viola! They self-deport. BUT, ALL the States have to do that. Can't make it easy for them to run to another State - that's just self defeating.
I don’t think that works... Illegal immigrants are deeply entrenched in our economy and the workforce to replace them is not in place. Of course, some will self-deport, but others are working and earning a living and they will likely not...
There is an interesting comment about the Bracero Program above that may holds some answers...
