I just noticed that I have sent our civil marriage statement instead marriage certificate to CIC
I have UCI and have used it in PR & OWP application, so should I just mail certificate to them and explanation with it? Or wait they possibly send whole application back or just request certificate?
This feels terrible after all hard work. And especially when also lost package tracking number so we don't even know is our application at the destination.
