Multiple H1 transfers

Hi Anil,
My current H1B I94 is valid until Feb 2026 and I have two offers say from Company A and B. I have my I140 approved as well. Below are my questions:
a) Can I initiate H1 transfer with both employers simultaneously?
b) If the transfer to company A is rejected, will it have any impact to H1 transfer to company B?
c) Assuming both the transfers are approved, I hope it’s my wish to join any employer post approval…?

Thanks.

A. Yes
B. No effect
C. Yes, your choice

Thanks a lot for your speedy response.

Hi Anil,
Forgot to ask this question…is there a concept of bridge petition in the above scenario…?
