I'm in India. My petition(non-masters, new H1B) is approved through my current employer(A). But my employer is not initiating the stamping process. I have the soft copy of the approval notice(I797-B) and is valid till Jan 2014. 1. If I change the employer, can I go for stamping through the new employer(B) ? 2. If yes, what is the process for this? What are the details that I should provide to (B) like petition number etc.? 3. What if (A) revokes the petition before my stamping happens through (B)? 4. What are the chances of successful stamping in this case? Is this a problem - changing employer before the stamping itself. Pls help we with these. Thanks in advance.
