I have an academic year FLAS. From what I understand, you have to be enrolled at the granting university to apply. At least that's the way it works at my school, even for the summer FLAS. Maybe it depends on your school- perhaps you could ask someone in your fellowships/fin aid office? I found the FLAS application to be pretty tricky, because the personal statement is so short: I think only 250 words! Not really enough space to say anything more intelligent than 'I did this stuff, I think this stuff is interesting, please give me money!' Other than the personal statement, there is a one page application form with basic information, and a letter of recommendation.
