Thank you! Yeah, maybe once my husband does his medicals something will come through, but I kinda doubt it since, as you say, a number of people have received the notification of transfer prior to medicals. If I want to put on my speculating detective hat again, I wonder if citizens living abroad are always sent to their local VO. I think all the cases sent to CPC-M thus far had the sponsor living in Canada.
It's not ideal but also not the end of the world if it's been sent to Vienna rather than Mississauga, but my restless overactive brain would certainly appreciate the confirmation!
