We got our PPR (outland, but in Canada) on March 14 and sent our requested documents right away. They were signed for at CPC-Ottawa on March 17. We have not yet received COPR back in the mail. I'm starting to worry that it's because the return envelope that we enclosed was a half size Xpresspost envelope instead of a full-size one. Maybe they didn't want to fold the COPR? Has anyone else had this experience?
