I was wondering. How old should you be to apply in a foreign exchange program for high school in the United States? I have been very curious as to why some information on the web say that the eligible are those 15-18 years of age and also thos who have not finished at least 11 years of school (excluding kindergarten). I want to apply for a program and my aunt has been telling me to go for it. She sayas i could live with them until the program expires but I'm not really sure how I can go for it. How do I start? The only thing I am needing to know right now is how old I must be to be eligible
