I have.
3 times...
First time, when it was 6 months and 1 week => I was told that the application is under review (background check), but the agent said I cannot tell you how soon it will be processed.
Second time, when it was 6 months and 3 weeks => The agent told me that he can give me an update only after September! When I asked if I have to wait until September until my application gets approved, he said it can be anytime from now till September!
Third time, when it was 7 months and 1 week => Another agent told me that eligibility, medical, and criminality have been passed and someone is actively working on my application. He said their deadline for EE application is 1 year, that's why his colleague said that he cannot give me any update until September.
Well, I found their system so inefficient! I have lived in Canada for more than four years. Do not even have a driving ticket. I got my student visa 5 years ago, and my work visa 2 years ago. I am just wondering what is it that they are looking for in my background that they have not already found it after all these years?!?
