I disagree with students studying abroad. Huge expenditure may be needed to study overseas.
In addition, parents cannot supervise their children when they cannot see each other for a long time.
Students may even miss their friends or their living places.
Moreover, students abroad may not be familiar with their own culture as they aren't living in their own country or region.
So in conclusion, I cannot see a reason why students have to study abroad instead of in their own place.
