That’s a completely ridiculous stance. Most international students are part of exchange programs meaning that for everyone attending one of our schools, one of our students gets to study abroad in a school from their country. These exchange programs allow people to be exposed to new ideas and perspectives and promote cross-cultural understanding, both by our country’s students experiencing other cultures and from foreign students sharing their perspectives and experiences with people at home. Isolating ourselves like that would reduce the spread of knowledge and ideas, for literally no reason.
