Can I transfer H1B petition when its sent back to USCIS for review

[manigupta]

I attended H1b visa interview in New Delhi but the consulate after the interview sent the petition back to USCIS for review.

I want to know if I can transfer my petition to new employer when its under USCIS for review. Will the new petition be cap-exempt ?

What are my options if USCIS revokes the petition and also my options before USCIS takes any call ? Please help me regarding this quickly.

Hoping to hear soon.
