I am currently working with company C.
I have two offers from company A and company B. They both have filed for my H1B transfer and both have been approved.
Is it possible that I join company A now and then can join company B after working with company A for sometime? or is it that after joining company A, a new H1 transfer has to be filed from company A to company B in order to join company B (since both the previous H1 transfers were filed while I was working with company C).
Any help in this matter would be greatly appreciated.
