To date, because of the pandemic and job loss, I haven't seen any change in H-1B or PERM processing (and in fact I would argue both have improved in recent months) but it's possible - even likely - that PERM processing will be impacted because of the job loss.
If I changed jobs and transfer went through, I’m still able to get an H1B extension with an already approved I-140 even if the new PERM filing is impacted, yes?
