There are several key steps in the comprehensive security, maybe these will be helpful for understanding the steps..Hi, got any update yet? My security also started in May 2023 and still on going. I applied in June 2022.
1. The csis part. If csis says your security is in progress. We can do nothing but waiting the screening.
2. If csis part is done, it will return to CBSA, (The cbsa note will reflect this)
3. CBSA will return the results to IRCC for the final decision.
In general, most C-check will last 9-18 months (the starting time is when the document is sent to security check, it is completely different from AR/AOR date, you can find this time in cbsa note), while some will be longer such as 2 years.
