I dont have approved I-140 with current employer yet, what if priority date is current?

[rd9999]

Hi All,

I have approved I-140 under EB2 category from Employer A with the priority date DEC-2015.

Moved to Employer B  in OCT-2019, PERM process is still in progress (very slow).

Employer A withdrawn I-140 in JAN-2020.

After today's April visa bulletin, dates moved to SEP-2014 for EB2, what if my priority date is current and my PERM process is still in process?

1. Can i still extend my H1b using I-140 (from employer A) to continue maintaining status until PERM process completes or i have to wait for PERM process outcome, which decides validity of my stay?

2. Any deadline for filing I-485 after priority date is current?

3. Any other option?

Your quick response is appreciated.

Thanks,
