You should be happy that CIC is at least doing your Security check. For rest of us Security check is still showing as "Not started"update: I got the GCMS notes yesterday. It shows that my security check begins from 2017-07-27. And there are two security screening (SS) marks after the starting day. I get that it means my files are still on the waiting list. When the third SS appears, it means that they begin to do the security check. If the forth appears, it generally means they will finish it in about one month. Therefore, there is a long way in front of me.
