@Atiranjeet yeah like edipre said you can't track the PERM but I will suggest to follow trackitt.com....This is what my lawyer said when I got AUDITED back in July...It will take 16-18 months or PD or One year from audit replied date...But in my case I got approved on end of June which is 17 months from my PD date and 10 months from Audit reply.
