Thanks a lot for the info, Rossie! Much appreciated. My concern is that my parents requested their PCC in China last September before they came to Canada on Super Visa. It has been now over a year. On CIC site it stated that "For countries where you have lived for six months or more, the police certificate must be issued after the last time you lived in that country", so my parents PCC for China should be OK; however, there is the gap between last September and now that they don't have anything. If they had requested the PCC now from China, then I assume that no PCC from Canada is necessary. What's your opinion, Rossie?
Thanks.
