Still waiting for the oath invite.
My timeline was along the following lines: Mississauga, Glenn Erin
Applied Nov 2013
Received sent letter Jan. 2014
Sent to Local Office: May 2014
Asked to come in for interview/test: Sept 2014
Passed the test 20/20 and interview was OK - given oath letter for week after, citizen Sept 2014
We applied for her a year later as she had been out of the country 6 times and each time was a month to two every time, I went out 4 times on business and were short trips, up to 2-3 weeks max. She was well over the 1095 days and we submitted all the documents + RQ letter + all evidences along with it from the start with the initial application for both of us. I think this may have saved us some time in CIC not coming back to us asking for more dox/proofs.
Hope this helps.
