Student Exchange Programs

I’m 15 and want to become an foreign exchange student for the summer of June - August 2011. Is it to late for me to do it? Will i be able to get a scholarship to cover most of the costs?

And i will have braces when/if i go to my other country, I have to go to the orthodontist once a month. Would I be able to go for 3 monthes due to this?

Will it be hard to learn how to speak a different language in 3 months?

Sorry I’m asking alot. I just have alot of unanswered questions. (:
