PERM Application on Office location change

Hi,

I am during PERM application process [submitted Dec 2023] and waiting for approval to continue to I140.

Apparently, there might be the need to close/move the office to another location or WFH within the same city.

In which case do I need to redo the PERM application again?

Can I still wait for the same one that was applied on Dec 2023 and apply I140 after it is approved?

Additionally, do I need to do anything with my current H1B which will expire on 2026?

I think a new PERM will be needed. Talk to your attorney and they will guide more.
