I dont know if its impossible to request to transfer files to another VO but for sure for us iranian applicants everything seems to be impossible these days. One thing for sure is that since government of Canada has absolutely no relation with iran, all iranian documents can only be validated in Turkey or maybe some other neighbor countries. I personally wouldn't even bother requesting for something like that. That would just add up to the delay anyway. We have no other option than waiting.They have increased staff in Canada and yet they transfer files to overwhelmed VOs outside Canada. IRCC said in September 2020 that it's impossible to transfer files between VOs! Now they are processing files that would otherwise go to Ankara in Beijing, Ottawa, and Mississauga.
It's a mess.
It's funny how their advocates were arguing on Facebook that it's absolutely impossible to move the Files!
Lets just keep each other up to date in case of any movement. Good luck guys
