Well, the strange thing is that when it got transferred to Mississauga we were told that it is being processed as inland application (we know this for sure because we kept calling them to keep track as we hadn't got AOR for long time and there was no updates at all). But the day we got AOR we called IRCC (because we wanted to confirm procedure about middle name correction) and the agent mentioned that it was being processed as overseas application (outland). Today we asked if there's a reason for this change but they are unable to say anything because they don't know as it depends on officer.
