How can I sign up to become a foreign exchange student in High School?

Has anyone ever been a foreign exchange student? Any advice on where I can start?How can I sign up to become a foreign exchange student in High School?I'm also looking into going abroad during high school. A lot of the foreign exchange kids that I met from school are through an exchange program called AFS. Remember you have to consider how long you want to stay, where and how much its going to cost. I never really considered the cost issue but through AFS they can offer things like financial aid, scholarships and fund raisers. Also you need to talk to your guidance councelor to figure out what credits will transfer over so you can be placed in your correct grade level. I hope this helps get you on your way!
