Hi Sourabh,
My employer had filed for the H1 transfer which was subsequently approved and I recieved my approval notice (I797 with I94 attached), during that time on USCIS portal my status was in post decision activity (Also mentioned as approved). After 2 months or so I got an automated email from USCIS (because I had registered for alerts on their portal) that my status has been changed and it is now showing back to initial review, below is the exact message on status change.
When I checked with my employer, they said it is due the form G28 which they have filed for their change of address ( they moved to a new facility recently)
I am not sure why it will affect my status, do you know if this is usual and if my status with them is in initial review although I have approval notice, can I travel and re-enter again ? Can my petiion recieve an RFE/DENIAL now ?

Thanks
