Spouse travel during H1B transfer

[ForazFerrari]

I am currently working with company A ( FTE) . My wife and son ( US born on India visiting visa) are in India and wife got her visa stamped (H4) with company A and is expected to come back to USA in july. I received another FTE from Company B. Due to the fact that premium processing is stalled, I understand it might take 4-8 months for my H1B transfer to get approved. However, Company B wants me to start working in a month or so ( when ever I have the receipt of H1B from them). How can my wife enter USA if my H1B from company B is pending in July? ( She has a valid visa in her passport from Company A..but I will be no longer employed with that company when she is returning).  Unfortunately, She cant return earlier than july due to some personal reasons.  please advise how to proceed. 

 

thank you !
