H1B Transfer with RFE on extension

[KV8]

Friends,

Need your suggestions, I got a job offer from one of the company and they are willing to do my H1B transfer in premium processing and my current first H1B will be expiring in 3 weeks and recently received an RFE for the extension from my current employer, what are my chances to move into the new company, Your suggestions will be very helpful.

Thank You.
