c. PERM and i-140 is approved and Active with Employer A
d. My priority date became Current in 2018, visa number was available, but did not apply for AOS (i485) since I already resigned from Employer A and moved to India in 2012
e. Employer B applied for a New PERM for me in Nov 2020 and it is approved June 2021, while I am in India
