Hi, I have sent my PR card renewal form by mail on March 15th this year and I still haven't heard anything from cic nor I can check anything regarding its status. Everytime I check the status online, it just shows my son's sponsorship application but absolutely nothing about my PR card renewal. I tried contacting cic via phone and it's always on "line busy" with a busy tone. What can I do to check my PR card renewal status itself? Thank you.
