I have been asked for COPR today after my oath. Very strange because in the oath instructions it says "permanent resident card OR confirmation of permanent residence". I cut my PR card in front of the agent and then he asked me for COPR. I explained I don't have it. He says I need to have this document because it's very important and I will need it when I retire. But he did not say the consequence if I don't have it. Then he just asked me to email the signed oath form.
So what's the point for him to ask for COPR if it is not absolutely required?
