I am currently in US working for employer A on L2-EAD visa. I have been getting regular pay stubs.Employer A has applied for my H1B petition (Cap Exempt, i.e Out of Cap).I have received the acknowledgement receipt but have yet to received the approved petition. Once I get the approved petition, can I immediately join a new employer B through H1B transfer? Or is there a requirement that I need to have minimum of 2-3 pay stubs on H1B status with employer A before employer B can apply for my H1B transfer? Thanks for your time and help.
