I have been doing a lot of research on studying abroad, not as an exchange student, but has a full term full-time student. And while perhaps years ago international university is allowed even noncitizens to study for free, that Changed. It is important to check. Each School will have certain three programs that are taught in English, and there are actually more than you would think. Of course, there is the student visa requirement that a certain amount of funds must be ascertainable up to three years in advance, which could look like $35,000 in some cases. So even though it is definitely less expensive to study in Europe, it can be a lot of money upfront.
