FYI, my friend at Stritch tells me they don't do that any more.
In any case, most medical schools consider DACA candidates without prejudice (it's a bonus point, if anything). And DACA students can and have been accepted to residencies.
So, it's all up to you and your scores/grades/CV if you want to go this route. Fair warning: it's a tough, TOUGH road ahead, even if you weren't a DACA student.
