Didn't get much of a response on here regarding my earlier question - so I ended up going to talk to a recruiter again about what would be likely to happen.
General impression I got from him was that it would be viewed favourably (my interest and desire) - if I wanted to do it it would happen (either through a internet program, a 6 month, or a year-long SLT). However, if the military was paying for it, they would likely place me somewhere where the skills would be reenforced (IE, a French speaking area - Quebec most likely). This makes perfect sense - why pay me to take a course I will not utilize?
My Fiance's particular professional career (Sign Language Interpreter) however relies strongly on English - there is a different variant of Sign language for Quebec (essentially, she'd not only have to learn French, but another form of Sign language as well) - While I see the utility of using of my newly-trained language, would this likely tie me to the Quebec (Van Doos) in terms of regiment?
Still in the dark about these things, and would still love any insight that was out there.
