My H1 with my current employer is still in transfer and not yet approved. My previous employer's I797 still has a validity for next 1.5 yrs. My previous employer also confirmed that he hasnt revoked it. In this scenario, my spouse is applying for universities to do a CoS from H4->F1. For this to happen, the I-20/SEVIS needs my H1 copies. Could I provide my ex-employer's petition which is still valid? Or I have to wait till my current gets approved?
