Nearly every American has two years of a foreign language in high school, and nearly every college requires two more years. I started Spanish in 7th grade and ended up with 5 years of study. However, I don't use is and as such, I've lost it.
On the other hand, I'm fluent in French, and learned that in France, not in school.
In my experience, school wasn't a very efficient medium for learning languages.
There are also Hawaiian Language Immersion schools available in Hawaii, which I hear very good things about.
There is an American actress - can't remember her name - she speaks fluent French. I saw her in a French movie and spent half the movie trying to place her face. It turns out that she went to a bilingual school French/English.
And the Germans speak pretty decent English by now, so the payoff is not as great as it was.
Now, I'm not much better off than a first year.
