We live in a global village at present because the distances and barriers have reduced to a greater extent. This has happened due to the advancement of technology and better trade relations. As the nations are interdependent for one or the other thing, they try to improve and strengthen the international relations through various ways. One of the ways to do that is allowing the students of different nations to study in their country. This helps students acquire better education and have fruitful career while the countries get to earn the revenue and sometimes have better brains from the other nations who help to develop a foreign country.
