Dear Applicant,
This email is regarding the documents you submitted to our office for the issuance of your Confirmation of Permanent Residence (COPR).
After reviewing your file, we noticed that your
COPR will be valid until 2023/03/10. This means that you must land in Canada before that date. If you think you can land before the expiry of the COPR, then our office can go ahead and finalize your application.
If you need more time to land, then our office can request an extension. Please be aware that for an extension of the COPR to take place, the medicals will need to be reassessed for UCI 11******** - which can take several weeks.
