I have a valid h-1b stamped from company A in mumbai consulate recently. The stamping was done couple of months ago and is valid till end of 2015.
Now my current employer is willing to process my h-1b for a long term job opening with a better salary than company A. I have accepted the offer and my current employer has filed a new h-1b petition on premium processing.
Once the new h-1b petition filed by my current employer is approved, do i have to go for stamping again?
Is there any way i can use the existing h-1b visa from company A to go to US without having to go for stamping process again?
