Thanks for your response. Since I'm an outland applicant, I don't have the way to link application to my account, like other inland applicants. Therefore, I wasn't able to know the mailing progress, etc. Please correct me if I was wrong.
It’s doesn’t matter if you are outside Canada.
1) Login to CIC account.
2) Go to section "Link an existing application to this account". Click on "Link application to this account" button.
3) Select category as PR Card
4) Select "Unique Client Identifier (UCI) and Family Name"
5) Fill required details (please make sure capital, small, comma etc.)
6) Provide landing date in "Date you became a permanent resident"
7) Click on search my application.
8) after application searched make sure you submit application else not linked.
One you have successfully linked your application it will shown you as "Submited" status and once it is ready for dispatch it will go into "Approved" status.
