My company filed PERM in November 2014 and received an RFE in April, which we responded to immediately. In the meantime there's still no news - the application has been pending for almost 10 months. The online status shows as "pending" but that's it.

What happens to PERM applications that receive an RFE? Are they sent to the back of the queue? Is it normal that it takes 10 months from the initial filing date?
