once they overstay their visas they no longer have legal status. they are immigrants.Illegal immigrants don't get visas.Of course, I don't know what you mean by "Close the border". 40% of illegal immigrants simply overstay their visa's. If you are suggesting that we stop issuing visas, I guess that I am against "closing the border".
You're mightily confused.
ta-da! presto change-o, illegal immigrants!
