I got my H1B visa stamped in December - 2012 which is valid upto September-2015, this visa is still not utilized means my petitioner employer does not have position is USA.
I am looking to transfer this visa from India itself to another company in USA. While searching i got many calls from many consultants to fly on my H1B visa which is still with company A. The consultant (Company B) will provide me their offer letter. Company B will file my h1b transfer when i am in US.
Is this a valid scenario, can i fly to company B on Company A visa and Company B offer letter? How reliable this is?
