My PD for Eb2 is Apr 2011
I have filed my i 485 in octo 2020 and recieved my ead and adv parole
Now my PD is likely to become current in eb3 final action chart.
Should I downgrade to eb3 or stay put with my eb2

Its your personal choice and the inclination of your employer to file EB3 i140 in premium or not.

Unless, you have that data, its difficult to make that decision.
