I am March 2013 case having sponsored my wife. Recently got PPR from LVO. Following is my timeline:
Feb 2014: File transfered to LVO.
Sep 2014: Request for Urdu Nikah nama.
Oct 2014: Request for RPRF and Re-Med.
Nov 2014: Passport request (no PPR1 and PPR2 separately. Just one request).
Wife was already in Canada on TRV so asked LVO if it is possible to send passport to their office. They asked to send passport to Ottawa office instead along with a copy of email and pre-paid envelope (PHEP required only if sending to LVO).
Good luck to everyone. We all deserve that.
