Miguel is correct. Most firms, unless they can bump you up to Eb2 or EB1 aren't even bothering with GC sponsorship at this point, since it has almost no chance of being approved while the employyee is still working for that company. They don't want to undertake a costly process from which they will almost never benefit.
They only start looking seriously at GC if the employees H1 clock is running out, or if he is now inline for a promotion that would get him EB-2 classification.
But USCIS will continue to process the I-140 (I-130 is for family sponsorship, of course) even if priority dates are backed up. In fact once you do PERM you MUST file I-140 within short period. It's the I-485 that aren't being accepted for EB3 unless you've been in the pipeline since almost before 9-11!
