You can link your PR card using your UCI number and Family name. Below might be usefulReading the link application on the my CIC account it seems that the option is only for those who applied through mail. So, please let me know if I can link my application even though it was submitted online. I got my eCopr in July and since then waiting for my PR card and there's no update on PR portal. Also, how does linking online applications help to get updates? If, someone could explain me, I would appreciate it. Thanks
