To be fair, the DACA / DREAMERs were invited here.  But the reason they were invited was a breathtakingly cynical ploy by O'Bama to pump up the democrat voter rolls via chain migration.  Every single one of the 0.8 - 1.9 million DREAMERs will end up as an anchor for chain migration of their extended families, say 2.4 - 7.6 million additional illegals.

You don't have to deport anyone.  You have to shut down chain migration, anchor babies, and make sure that anyone in the country illegally has to leave and get back in line behind everyone who is doing it legally.  Legalizing these people is an insult to everyone following the law.

If it were me, I'd make sure none of these people can ever vote.  And I'd shut down all access to the welfare state, social security, and government paid health care.  Build the Wall.  Pass Tom Cotton's RAISE Act, and enforce existing immigration laws vigorously.  Cheers -
