Even if the college pays tuition, room and board, you have to think about how you will pay for visa fees, travel and airline expenses, a laptop, books, dorm accessories, and spending money. That’s at least $10,000 worth of expenses that the college won’t cover, even before you even sit down in your first class. Your work opportunities will be limited and restricted on a student visa.
Take your shot, but the other posters are serious when they tell you to have backup plans that you can afford in your own country.
