Hi all,
My partner and I started the application process in July 2012, so here are the timelines and updates from beginning to end we experienced.
Category: FAM Common-law. (My fiancee is Korean, and we both live together in Canada during this process)
Visa office: Seoul, Korea
All meds and payments were done in advance before mailing the app.
Full Application mailed to Mississauga office: July 13 (arrived in Mississauga on July 16)
Sponsor App AOR (UCI & App# created): August 18
Sponsor App Approved (letter sent via email): August 21
App sent to Seoul, Korea Visa office: August 21
Seoul office AOR: September 6
Applicant App Started processing: October 16
Request for more info (Korean entry/exit certificate): October 16
"Decision Made" status: November 6
CoPR received by mail at Canada address: November 13 (actual issue date on CoPR paper is Oct 30)
So exactly 4 months from mailing our app to receiving the CoPR in the mail. I think we had lots of good luck on our side
