USCIS was supposed to release new specifications for advance parole that dealt specifically with DACA. With this, the border patrol will pretty much have clear and explicit instructions as to how to handle DACA cases, i.e. person has DACA and approved advance parole — let them in.
It seems they've put that on the back burner for now, though, since they announced that several months ago.
