As you know in terms of criminality, we need to prepare police clearances for our mother country and other countries that we stayed for more than six months. It seems like CIC request RCMP reports to check whether we committed a crime here, as my note mentioned that my RCMP report is clean, which I haven't submitted. Thing is if there's a criminal whose name is similar or identical to an applicant, CIC seems to ask the applicant a RCMP fingerprint. I guess having common name could be an obstacle in this case.
However, speaking of security, we, as applicants, got nothing to do but wait. Agencies such as CSIS(Canada Security Intelligence Service) are involved in order to weed out those who have been, or are involved in espionage, subversion or terrorism. As I know it takes two to three months, but some cases take over a year. Hope latter is not our case.
