International stuents are students, usually in early adulthood, who study in foreign educational institutions. While most universities have official student exchange programs, some well-funded high schools have them, too. Although some students travel abroad mainly to improve their language skills, others travel to advance their specialized studies. Still others study abroad because suitable tertiary education is either in short supply or unavailable altogether in their home countries. In addition, in many parts of the world, a foreign degree, especially if earned from certain countries, is honored more than a local one.
