Get the trains steaming and buses rolling!
Oh and let’s not forget to mention, once the trains are steaming and buses are rolling, and knuckles are knocking at doors and busting them down, apprehending invaders and their aiders and abettors ... many of these nasty invaders will self-deport because the environment will be no longer nurturing for them. That will prove to many preferable to the process of detention and deportation and the dread of a DHS call from a neighbor getting them yanked out. Add in the fact that they no longer will be able to swarm 50 people in one apartment unit, because that will attract attention. So their living expenses in the US will go up, and fewer landlords will be willing to rent to them because they will face fines and imprisonment for doing so. So yes indeed deport, deport, deport.
