My Priority Date is Sept-2009.
I have an approve Labor which was approved in july-2018. I am within the 180 days of labor approval.
I also have an approved I-140 which was approved in premium in august-2018.
1) Can i file new I-140 in Eb3 with Concurrent I-485 on October-1st, since I am within 180 days of Labor approval
2) what happens if new I-140 in Eb3 is rejected?
3) What happens if I get EAD based on new Eb3 category and Eb2 moves faster? am i eligible to move back to Eb2. My first priority is to get EAD and AP so that traveling outside USA is easy.
4) I have already moved from Eb3 to Eb2 once? How many times does this upgrade/downgrade is allowed? can i go from Eb2toeb3 and then go from eb3 to eb2 again after I-485 is filled? Can upgrade/Downgrade be done after filling I-1485 too? or it can only be done before filling I-485?
5) If i got I-485 filled in Eb3, do i get to port to Eb2 again if needed or I am stuck with Eb3?
