Can I continue working when my OPT has expired and H1-B is under review?

Hi,

My comapny applied for my H1-B visa in April 2012. For my case I got a RFE for which the company supplied the necessary documents and as of now my RFE is under review by the USCIS. As I was working under OPT I was able to work till 30th September 2012 but now even that has expired.

So can I still continue work waiting for my H1-B?

Also can I stay in the US legally waiting for my H1-B?

Thanks.
