Well, first you ll need a passport. Don t know whether you need a visa. But info about passports would be at the Canadian government s official website, I would guess - unless you re talking about Vancouver, Washington, in which case you d go to your local post office. The US State Department s website has info on entrance requirements for the US. Or, perhaps the camp you re thinking about attending has info about that.To get to Ithaca, you d need to fly into Syracuse and then have a way to get down to Ithaca. The camp may provide transportation. You d need a way to pay for air fare, of course.If you re under 18, you probably can t travel without your parents permission.Hopefully, you can convince your parents that this is a wonderful opportunity for you to get an education at a first-rate university. Perhaps your high school coach or a teacher or counselor at your school can talk with them and explain things. Or a minister at your church, if that is an option.Good luck to you. I hope you get to attend the camp and get to attend Cornell.
Sounds like you are stuck in hell.You need a passport to even visit the US.
