Student visas are non-immigrant visas that do not require the holder to obtain citizenship. Any prospective student seeking higher education in another country must obtain a student visa for that country. Most countries will issue student visas in order to allow foreign students to attend school within their borders. However, in most cases the student must be enrolled at a postsecondary institution of higher learning. Foreign exchange students must therefore usually obtain a different type of visa, such as for temporary residence.
