Hi Michelle,
You replied to me when I was worried that i haven't received AOR and the rest of my family did. Now it's my turn to encourage you.
I got AOR by email on July 25, while the rest of the family got it on July 14. My application was already in process. I know because I checked the status using UCI from the landed immigrant document, or the receipt number. When I click In Process link, it says that they sent me correspondence and Discover Canada guide twice, once on July 14 (like the rest of my family) and once on July 25 (when they sent me AOR). And it also says In Process since July 20.
So yeah, mine is different than the rest of the family, and also a little weird to receive AOR after In Process.
But I think everything should be fine, as long as it is In Process, I am expecting the test invite.
So don't worry
