2. Slovenia
Small country at the foot of south-eastern Alps currently offers around 150 programs completely in English. Needless to say, all of them are free of charge, and only college-related expense that international students in Slovenia have is registration fee that is more than modest – slightly more than $30 a year. Apart from seamlessly nonexistent tuition costs, Slovenia offers relatively low living costs. You probably won’t survive on $500 per month, but anything above that figure should be sufficient.
