Hi Panditdeep,
My priority date is 11/13/2012, my EB1A I-140 approved on 08/05/2014. USCIS received my EB1A I-485 application on 09/05/2014, I got my EAD & AP in Dec 2014 and still waiting for I-485 approval. Raised SR and got a response saying that my application is in line for processing and adjudication, please let me know if you have any idea why its getting delayed this much. Thanks !
