背景:PhD学历,在college教书.

诚心请教过来人,I-140 Part 2 Petition Type中应该选哪种?

是

d) A member of the professions holding an advanced degree or an alien of exceptional ability(who is NOT seeking a National Interest Waiver)

还是

e) A professional (at a minimum possessing a bachelor's degree or a foreign degree equivalent to a U.S. bachelor's degree) or a skilled worker (requiring at least two years of specialized training or experience).

是不是两种都是EB-2啊? 优先有什么不同?

多谢前辈点拨一下 :)
