回複：if your H1b can be approved, you should be H1b!

Based on my own experience, if you apply OPT first, then H1B, even though your H1B is approved earlier than OPT, you should still be H1B. I applied OPT in the last April, but I didn't get approvel until July 18. Since I thought they might deny my OPT, I applied H1B (premium process)at the begining of July.Finally my H1B was approved on the July 12, so it was 4 days earlier than my OPT. The international office of the school told me that I should be H1B and they informed Immigration office that I ended my OPT.
