Upgrate to H1 premium processing

My H1 application was filed on 4th june 2012,but it is still in initial review stage

What is the usual time to hear from USCIS?

can I upgrade for a P.Processing? Will it improve the chances of hearing back from USCIS?

USCIS takes 2 to 4 months to process the petition under normal processing. You can very well upgrade your petition to preminum any time. In that case you will be able to recieve the decision with 15 to 20 days.
