Deep down, I do not think that's going to happen. We would have known this by now!

Think about the positive anchors in this situation:

1- DACA has been around for 5 YEARS and a tiny fraction of people (in comparison to the entire immigrant community) have benefited from the program. There is NO WAY he can get away with ripping our lives apart. It would be a political disaster and USCIS/DHS nightmare.
2- There is substantial and significant support around this issue from congress, rights groups, and even those who voted for Trump. Even GOP hardliners are sympathetic towards the issue.
3- IF he was going to flat out cancel the program, I have no doubt he would have done it by now.
