i'm in comp A now. my transfer to B is approved while the transfer to another comp C is in process. can I join B and wait for the transfer to C is approved. when the transfer to C is approved, can I join the comp C directly without doing any other paperwork ? what's the best way to join C from B ? can I go out of the country and get stamping done for company C and enter to USA with H1B stamped for comp C ? please advise.
