How do I validate a Confirmation of Permanent Residence or a permanent resident visa if I live in Canada?
If you already live in Canada, you have two options to become a permanent resident:
You can make an appointment at one of our offices near where you live in Canada. To do this, contact us by using this Web form.
If your permanent resident visa (or one of your family’s) expires in two months or less, please indicate that you need urgent processing.
If you are not able to make an appointment as set out above, you may leave Canada and return through an international airport or a Canadian land border.
When you arrive, an IRCC officer will interview you, and grant you entry into Canada based on the information in your visa.
