So here is my timeline:
Applied from Brampton
Application received: December 15, 2017
AOR: Feb 1, 2018
In-Processing: Feb 28, 2018
Request to appear in exam: Sept 4, 2018
Exam Date+Interview: Sept 20, 2018
Now during interview, interviewer went over all stamps on my passport. There was one stamp from 2013 (US stamp for I90, I do have alot of land border crossings) that I didn't have listed in residency calculator (possibly because I didn't remember my entry date in Canada). At this point interviewer told me that because I have so many land entry/exit between Canada and US and because I had one entry/exit stamp that was not reported on residency calculator, they would have to go over my records with CBSA to confirm I meet residency requirements and this may cause delay in my application.
Now my concern is that I did select checkbox that gave my consent to IRCC to get my entry/exit information from CBSA. Shouldn't the interviewer grab my information from CBSA ahead of the interview. And because I had selected the checkbox, should there be any delay in my application?
Does anyone know how much time can this take?
