An exchange student is a student who temporarily moves to another country to study at a school or university. This program allows students to experience a different culture, language, and education system while living with a host family or in student housing. Exchange programs are often organized by schools, universities, or organizations like AFS Intercultural Programs and Rotary International. These programs typically last from a few months to a full academic year, providing students with the opportunity to make international friends and gain a broader perspective on the world.
