scalemx >< haha
anyways, you should really consider scalemx's 1rst point. In order to live there, you need a good reason first. Having an American law degree will have a lot of influence.
2 semester of Japanese will allow you to talk to a child, ask for directions, or hold a very simple, boring conversation.
my advice is, take your time, because you have a lot of it. it seems like you are thinking ahead of yourself, like most of us do when we are in highschool.
