You have two BIG problems.1. You must qualify for a student visa in order to study in the United States.2. You would need to be accepted as a student at the school you want to attend.If you are trying to attend on a sports scholarship, and are accepted the school will assist you with both of those problems.Once you have passed both these hurtles, ask again.
The age of majority is the USA is 18, and I am assuming it might be the same in Canada. If you are old enough and can be financially self-sufficient, then you could consider availing yourself of this opportunity. You will need to be sure you can stay in the USA that long and will have to do any paperwork in advance.Ithaca is gorges!
listen whatever happens if you dont take the opportunity you will regret it for the rest of your life...do what you have to do, if you are successful in school your parents will have to hold their tongues
