I am currently employed with Company A and also holding L1 visa. Company B have process my fresh H1b for 2014 through CP and got approved. There is some issue with Company B so they will not provide me the I797 approval but I have receipt no of H1B through which I got to know that my Visa is approved. I am currently in India still employed with Company A.
1. Can I make H1b transfer without I797 approval notice to another Company C without joining Company B?
2. Is it possible for my current company A(who is holding L1 also) to file New H1 under quota exempt?
3. If I go to US with my Company A’s L1B and later wants to transfer my H1b with Company C then will it be possible?

Please help!

You can't process your case without approval notice. You need to discuss this issue with the company's attorney only.
