Old Priority Date was not Recaptured

Hi everyone!

I hope you could all shed some light on my concern. You see, my old priority date was May 1 2007 but since I was abandoned by my previous employer, I was not able to leave my home country. Luckily, I found a new employer who processed recapturing of the old priority date. Yes, the new I140 was approved but to my dismay, USCIS gave me a new priority date which is June 27, 2014. They were not able to recapture my old PD. My attorney sent a request to NVC to send my case back to USCIS. I checked my USCIS case status and it showed: "The Department of state sent us your case for review. We are reviewing it and will notify you by mail when we are done." Now my question is, how long usually does USCIS process the correction of priority date? And would there be any chance that they will not approve the correction?

I hope you can give me some advice on this as I am getting frustrated. I have waited too long for my old PD to be current but due to this unfortunate error, I was given a new PD. I don't want to wait again for another 8 years or more. Please help! Any information will be greatly appreciated. Looking forward to hearing from you all especially from those who had been in the same boat as I am.

Thank you very much.
