My mother received the Confirmation of Permanent Residence documentation in the mail today. She resides in Canada with me, so we have two options for there to get her permanent resident status as directed by IRCC 1) Call the 1800 number to schedule an interview at a local office or 2) leave Canada and re-enter in order to see an immigration officer. The issue is that I've called the 1-800-242-2100 they gave us in the documentation and directed us to call and I cannot get through to a person to schedule an interview. What do I do?
