回复：[求助]请问OPT的EAD在生效之前可以Cancel麽?

(别毕业了 because of 工作还是没有影子)? This is not necessary good because you still need to pay tuition and maintain fulltime status if not graduated. If it is because your advisor still have project for you, you can work under OPT after graduation and don't have to pay $$$ to be enrolled.
