Well, there's a lot of things to consider—like technical shit. Aside from money, there's immigration. You'd have to learn the UK's policies on foreign students/residents, etc… But, yeah, if you can go to school abroad, I say fucking go for it. Without a doubt. It's an interesting thing to do and an interesting way to go to college and life is short, so if you can pull it off or if it CAN be pulled off, do it.
