I am currently employed and my current work authorization is EAD on L2 dependent visa. My husband, who is the primary visa (L1) holder, is considering a job change and moving to H1B visa hence I will also have to move to H1B visa since my L2 visa would not remain valid once he moves out of L1 visa. My H1B visa was filed earlier this year by another employer, which was approved and I have details for the same. Based on that approval, can my current employer file my change of status to H1B? Would the current employer require any documents from the employer who filed my H1B (other than approved petition) for filing the change of status?
