they had written on the board that take the following documents out and present to officer when you are called.Did she ask for it or you just told her you don't have it
Confirmation of permanent residence was first document on that list, along with two ids, all passports PR cards etc.
So when I got to her I just told her I don't have COPR. She said oh thats ok, what happened to it, i told her it is in a safety deposit box and she said its fine.
