Confirmation of Permanent Residence

您好 猴君，
我是本人去年7月递交的PR申请，全家三人一起递交，我为主申请人。后因有事回中国至今，未和移民局更新地址信息。后在国内收到补料，体检等信息，都一一照做完成。刚刚8月末有收到邮件标题为 “Ready for Visa. Please use this letter if you or your accompanying dependants are currently residing in CHINA”看标题， 我以为可以三个人的护照寄去贴签，但看到正文内容，又很迷惑。“The processing of your application is almost complete. To move forward in processing, please refer to the instructions below to submit passports from your family member(s) abroad. IRCC will contact you soon with next steps for processing your (the principal applicant) COPR from inside Canada.”
请问，这个邮件内容，移民局是不是按照我人在加拿大，副申请人在中国这样情况处理的？要求我在中国寄家人的护照去贴签，在稍后按照加拿大境内的程序为我办理，是这样吗？
麻烦，谢谢。
