so if 485 pending >180, 140 approved換工作 there is not problem?

Aagain, so if 485 pending >180, 140 approved換工作 there is not problem??? but if you get your green card you'd better stay with your current employer (not necessarily the same company that sponsered your PERM application?) for more than 6 months? It's sounds contradictory to me.

I am still confused.
