Forms needed for H1B transfer

[random_indian]

Hey

I used to work for a Software Company (A), which sponsored H1B for me. Currently I am on that H1 visa which expires on Sept 2013.

I recently moved to Company B, which is in the process of transfering my H1 visa. I started working for Company B, as soon as I got my H1B transfer receipt. (Transfer is not done yet)

Now, I am planning to move to Company C. Company C will start my H1transfer process. Should I show my H1B transfer receipt to Company C
