NEED UR IMMEDIATE HELP : H1 transfer

[blueie]

I am currently in H1 (started from 1-Oct) through a consulting firm.

Got a full time employment from a leading sw company and did H1 transfer thru PP. And they asked me to join immediately after H1B is transfer (before approval). I suppose to join them tomorrow.

But when i check H1B transfer status is in RFE and NOT got the mail from USCIS so far.

(1) I spoke to my new employeer, they wanted me to join tomorrow for sure ; and cannot postpone my joining date due to the business reason.

(2) What if H1 transfer gets denial and my previous consulting company NOT revoke my H1 petition, Can i able to join him back (If he is interested to offer me again) ? [Without further more notification to USCIS]

I don't want to screw up too much and wanted to go with legal possible solutions.

Kindly help me asap, I have only 24 hrs to decide.

Either i have to revoke my notice from consultant OR join my new employeer tomorrow.

Best Regards,
