My experience
I applied citizenship in Sep.,2002. I was asked to do finger print in the begining of 2003. Last months, I called CIC. I was told that RCMP had completed investigation, but I still need to wait at least 3 months. What does it mean? I have already waited nearly 2 years.
Then, I contacted MP of my comminty. A lady in his office called me back and asked me details about my case. She told me that she will send a formal enquiry about my case.
The next coming week I got notice of citizenship test amd oath. I am not 100 percent sure if it is because of this enquiry. But we should do something not just wait.
