Guy name Shivam got COPR under International Graduate Stream. Mark Holthe went live with this Guy.
Few updates from him
1) After your background check you will get Pre-Arrival letter which is not useful for us. Its just their regular system. It will only be useful for people who are outside of canada.
2) Your will receive a link for a portal, where they will ask few question regarding current place of living just to confirm that you are currently in Canada. This is separate portal.
3) Once that is approved, you will receive link to upload photo for PR card. Once photo is approved you will get e-COPR. (In Shivam's case, as soon as he submitted his Photo e-COPR was already there on portal)
4) On e-COPR its mentioned that you can not travel on e-COPR.
For more information you can watch video.
This will clear procedures at every step.
Let me know if I am wrong somewhere.
