回複：請問Perm和綠卡可以自己辦嗎

Sure, DIY. I DIY. Lawyers do not know more than you.
I think the most important is how to pursuade your university to cooperate with you. By the way, if you teach courses, and your were selected under a competitve recruitment process, you do not need to go through the complicated advertising. But remember, your case must be filed within 18 months if you want to take advantage of the optional recruitment process for college teachers (before PERM, it was called special handling).
