Hi Ron , I got my PERM approved through my previous employer A in Aug -2013. But I didn’t file my I-140 through employer A. By end of aug 2013, I took a new opportunity with employer B. Currently I am employed with employer B and my h1 extension got approved which is valid till Jan-2017 which is end of my 6year Cap. Now, my current employer B is planning to file my green card. Below are my questions · As per my understanding Priority date is assigned when PERM gets approved, is that correct? · If yes, can we port priority date which was assigned during previous approved PERM which was filed by my previous employer A? · During which stage in green card process, we should consider to port the priority date when my current employer B files my greencard?
