Well, I'm already out of high school. I went to University.
Really, if you've got the grades and you've got the smarts, there's no better option than to go there and get some kind of degree. While it's much better to get a degree in something that you plan to use when pursing a career, any kind of university degree will aid you in getting the job you want.
As for the whole American University thing, you're kinda right. I haven't met anyone at my university who hasn't taken a foreign language for at least three years in high school, but they don't necessarily make it a requirement. Some very well might require it, but not all. The loophole in this is that most American Universities are competitive in the amount of enrollments they'll receive per academic year, so chances are the students who studied hard and took foreign languages in high school got most to all the spots. :D
