Hi,
1- I just find out that for some nationalities CIC doesn't request security check through CSIS which makes their application a lot faster (CIC will run the security check which is not that deep). For other people, they will request a security check which will take 3 to 6 months.
2- The security check is out of CIC hands, so even if you call them they cannot give you more information. You just have to wait.
3- if you received your GCMS note, you will see that the security check is not started or is in process and the due date for that to complete is exactly at 15 months from when CIC received your application. Interesting...
4- However, this doesn't mean that it will take 15 months for sure. The security check result might come faster than that.
5- You can order your GCMS note online and you will receive it by email. it will take 30 to 35 days.
