I got my H1B from Company-A and i have been working for them from 1year. Now I got a project from company-B and the company-B has filed for H1 transfer and got approved. but Now I decided not to join Company-B and work for Company-A itself. (Company-A doesn't know about the H1 Transfer and I don't want to let them know also)

- What should i need to do to stay with company-A since the transfer got approved for Company -B?
Can I simply go and start working for Company-A now, even though Company-B got Approval!
- Suppose if the company-B revokes my H1B if i don't join them,will this be an issue about my status?
-Is it better to inform Company-A about all these transfer things ?
