Joining new company while h1 extension is in process

USA H1B Visa
1

Hi

My current employer filed for my H1B, I94 (both were expired by 30th Sept 2015) extension 07th Aug 2015 in normal processing which is still in process.

I am planning to switch company and new employer raised H1B transfer in premium processing. I am joining new employer after getting receipt number.

What would happen

If my new H1B transfer gets rejected.

If my H1B transfer gets approved but I94 didn’t get extended.

Can I rejoin my current employer who filed for my H1B extension if any of above case happens without going back to India. Please let me know.

If H-1 transfer is denied, then you have to either leave US or join the old employer.

If H-1 transfer is approved w/o I-94, then you have to either leave US and return on H-1 to get new I-94 or join the old employer.

You can join the old employer only if they have not withdrawn the extension petition and are still willing to hire you.
