I have lived in two different countries since 18 for over 6 months, so I have to present police certificates of both countries. One of the countries is my home country where I do not have any problem to get those documents. However, It is very difficult for me to get the other one from the other country because I do not have relatives or close friends to get them for me. I know some people have faced this problem and wrote a letter to CIC explaining their cases and eventually CIC would accept that. What should I do?
