My understanding is that NASA gets final say, and that needs to happen about 24 hours ahead of time. I believe tomorrow afternoon NASA will make that decision, and then Dragon will go into an orbit that will intersect with ISS's. I'm very happy. Not as happy as if there were no hiccough (SpaceX has some big enemies and they will be harping on this with the FUD), but things are playing out nicely.
