回复：请问:PERM EB2批准后140/485有可能被移民局改成EB3吗?

PERM and I-140 are Totally difrerent.When you submit your I-140,you choose your category EB3,or EB2.Choosing which category is based your job requirement,not your current job position and your education.Normally,company attorney would suggest you use EB3 if they think there is risk about EB2.
