H1B visa stamping

Hello Anil,

I am in a situation where i need help from you to understand my options. Please help. I am currently in India and have a two approved Consular(i797B) petitions from my original Employer A and H1B COE Employer B. Since Employer A petition got approved initially, i have applied for Stamping process with petition from Employer A and paid visa processing fees having an intention to travel to US on Employer A petition. I am yet to get a embassy stamping slot.

a) If Employer A visa is approved and if my employerA is delaying my travel back to US, can i travel to US with approved Employer B petition or is it mandatory to travel back US with EmployerA?
b) whether Employer petition B will be invalidated once visa is stamped from EmployerA
c) Would it be possible to cancel applied Employer A stamping slot and book a new visa slot for EmployerB with New DS160 forms if required

Please advise. Thanks

Regards
DK

You can travel to the US (and work for employer B) using the valid H1B visa for employer A.

Thanks Anil for your inputs.
