need your advise on an issue. Actually i have a valid H1B visa stamped under company 'A' till 2017 December. Now company 'A' is not responding to my emails. I have never travelled to United states. Also one of the managers of Company 'B' wants me to go to US on company 'A' visa and then planning to transfer my H1B imediately the day i landed in US. If you could reply me that would be helpful for me.
