Many university students routinely study in other institutes around the world as part of their degrees. Although students will often struggle with cultural and linguistic challenges while abroad they will also gain significant life experience that will reward them later on their careers. In my opinion students are far better of having studied in different country despite the challenges that they will inevitably face.
The greatest benefit of studying is that students will have life experience that will improve themselves as people that would have been otherwise possible if they had have only studied in their own countries. Being in another country requires people to push themselves beyond the norm into usually difficult experience. For example, when I studied i Indonesia and India as a twenty-year-old, I was continually pushed out of my comfort zone into psychological states that were unique and novel and that I had to adapt no matter what. These ultra-challenging experiences are paradoxically the main advantage of studying overseas because they make you grow as a person.
The main challenges that students will face while overseas will usually stem from cultural and linguistic differences. The differences can pose massive obstacles for people because they require one to move beyond the familiar and into the unknown which can often be awkward and quite scary. For instance, while studying in Indonesia I had to frequently make a fool of myself in order to communicate with the local people in their language. Oftentimes, I felt embarrassed and I longed to speak English and be in the familiarity of my own culture.
Studying overseas has become incredibly common while students will no doubt experience social and language barriers, it is in fact these barriers that lead to the main advantage of studying abroad which is personal growth. As contradiction of sorts, it is the hardship that ultimately makes the experience of studying abroad more advantageous than disadvantageous.
