The only reason I'm applying over here is that I will be looking for work as soon as we arrive, so didn't want to be in the situation of 'we'd like to employ you but you're only on a working tourist visa, etc'. Not sure if this would happen or not, but just wanted to try and cover all the bases.

It doesn't matter that you're boyfrind & girlfriend, as long as you've been together for a while it's looked on as good as a married relationship.
