As per my observation in few forums, most applicants from Jan, Feb 2016 with NDVO, whether FSW inland or outland, have not even got BG in progress till the end of 6 months and still waiting.
For me the AOR is Feb 25, 2016 (FSW Inland) file transferred to NDVO on March 07, 2016. BG still "Not needed"
But on the other side, all Applicants with Ottawa office as their VO have received all notifications + PPR as per the timeline within 6 months.
May be NDVO is busy processing education visas. Not sure when they will initiate PR processing for 2016.
