In their enforcement priorities list:
(c) Have committed acts that constitute a chargeable criminal offense;

Illegal entry is a chargeable offense.

(e) Have abused any program related to receipt of public benefits;

That can pose a problem for overstays (me). With those two, they pretty much covered us all. And if not, there's always this last catch all:

(g) In the judgment of an immigration officer, otherwise pose a risk to public safety or national security.

So anyone they *think* poses a risk, so it's pretty much at their discretion. You can say we're protected by DACA, but do you think that'll stop ICE officers if they're a big enough assholes? Everything is up to them on what they consider is a crime. This also put's our parents at risk as well. Once DACA is gone, which is a possibility, it's open season on us even if we still have EAD.
