If you or any of your accompanying family members are not normally resident in the area of responsibility of this office, then you should be aware that there may be additional delay in the processing of your application for permanent residence in Canada. This delay will result from the need to refer your case to the Canadian Immigration office which is responsible for the country in which you or your family members normally reside.
这说明移民局不是简单通过你的初表决定哪里的大使馆审理你的case,而是由移民局根据你的常住地分配你的case到相应的大使馆审理,比如你目前居住在澳洲,移民局会直接将你的case发到澳洲大使馆审理,而不是你初表上申请的BJ或者HK
