H1B transfer and time to move to new location


I joined a new employer who is in SFO. LCA filed based on new location and got my I797.

I live in LA, now how long do I have to move to that new location. Since it is going to be remote for a while I am thinking about to work from my current location for few months may be 6 months.

Can you please advice is it safe to work from different location for a while in my case?
