First, they all go.
Second, we can talk about immigration reform.
Beginning with Temporary Worker Visas.
You get to stay for a specific time frame; your family does not come with; you wear an ankle bracelet or chip...
And you go when your time is up or ICE actively hunts you down and you're never allowed back in again... ever...
Once your time is up and if you're still here, then...
Anybody caught sheltering you or employing you or handling money for you gets charged with a felony of some kind...
After the dust settles on all that we can talk about other aspects of 'reform'...
Quite probably beginning with a Quota System for each country...
BTW... "reform" does NOT equate to "let those already here remain".
