Hi Stacey!!
You guys have been in my thoughts recently so I thought I would pop on and see how you are all doing.... I am SO happy that you are nearing the end!!
As for the COPR, when I had the PPR come through I sent all the requested bits off that same day, had tracked and fast delivery and it arrived that night. The next day I then had my COPR come through on GCkey and then the paper COPR came to my house via signed postage the next day. I couldn't quite believe how fast it happened, but they have all our passport info and photos etc so I think it is more so a final clarification.
All the best, the moment you are reunited is so close now, and ever so rewarding.
