More INS and border patrol agents, that wall is years away from being able to stop the flow of drugs, and illegals coming here.
It would help if Everify was used and scum bag employers were fined for hiring illegals.
I like the idea of self deportation and any measure that makes illegals less likely to want to be here illegally is fine with me.
Eliminate their welfare and enforce E-verify, and most will go back.
