在Buffalo申请移民更容易被背景调查，调查的时间也更长。我的申请已经3年了（2002年4月投档），考虑到加拿大政府的工作效率，但愿再有两年有结果，早知这样，还不如在北京申请呢。
Applications for Permanent Residence from Within Canada
The Service is responsible for security screening all persons who apply for permanent residence status from within Canada. In 2003–2004 the Service received 44 907 screening requests—28 401 under the immigration program and 16 506 through the refugee determination program. The Service also received 4646 requests to provide screening advice for applications submitted to Canadian Immigration offices in the United States.
The median turnaround times for the Service to provide its advice in these cases varied considerably depending on whether the Service received the request in hard copy (paper application) or via Electronic Data Exchange (EDE).
For the immigration program, the median turnaround time was 42 days for EDE requests and 133 days for hard copy requests. The median turnaround times for the refugee determination program were 52 days for EDE requests and 114 days for hard copy requests. In 2003–2004, all requests from Canadian visa offices in the USA were submitted in hard copy. The median turnaround time for these cases was 153 days.
In 2003–2004 the Service issued 130 information briefs and 52 inadmissible briefs in response to screening requests from within Canada and the United States. The median turnaround times for these cases ranged from 14 to 20 months.
Applications for Permanent Residence from Outside Canada
For permanent residence applications that originate outside Canada or the United States, the Service shares responsibility for security screening with immigration officials at Canadian missions abroad. For these cases, CSIS only becomes involved in the process upon receipt of a request from the Immigration Program Manager. This process allows the Service to focus on higher-risk cases.
In 2003–2004 CSIS received 24 243 requests for screening under this program. In addition, the Service's Security Liaison Officers were consulted on 4814 cases. The Service issued 25 information briefs and 21 inadmissible briefs. The median turnaround times were 238 days for information briefs, 106 days for inadmissible briefs and 5 days for non-adverse advice.
