International students are defined as students who study outside the boarders of their home country. In 2013, the Organization for Economic Co-operation and Development (OECD) stated that 4.5 million students globally were studying outside their home country.
Professors Jenny Lee and Charles Rice, writing in 2007 on an article titled, “Welcome to America? International student perceptions of discrimination”, recognised that international students studying in the United States (US) provide the US with a diversity in student populations and an awareness for other cultures and countries.
Furthermore, they also provide economic value to the US in the form of knowledge and skills in a variety of fields, such as technology, health, and engineering. Those who go the US as international students and stay there add to the intellectual property of the US. Those who go back to their countries of origin also play a similar role.
