I think this issue has been debated a lot of times. One does not have to wait for 180 to change jobs. The only chance that the I-140 can be revoked by sponsering employer is that one leaves before 180, company notify INS immediately, and INS act on it before 180. If my I-140 has been voided by previous employer, why am I getting RFE? They should have denied my case already. Thanks for your advise anyway.
