There were an astounding number of immigrant citizens who came here "the right way" (which mostly involves marrying a citizen) and voted for Trump specifically because they see everyone else coming as "criminals". They got in, and wanted to pull the ladder up from behind them.

I wonder if they realize that ICE doesn't care about their paperwork, they see some who is on the wrong side of the "Peter Griffin in a Fez" scale and just act. All of their papers, which they spent so long to get "the right way", will be dismissed as forgeries and they will be expelled to some foreign country just like the "criminals" they thought they were punishing, because ICE doesn't see the difference.
