A J-1 visa is a non-immigrant visa issued by the United States to research scholars, professors and exchange visitors participating in programs that promote cultural exchange, especially to obtain medical or business training within the U.S. All applicants must meet eligibility criteria, English language requirements, and be sponsored either by a university, private sector or government program. J-1 visa holders must return home for two years following visa expiration so they impart cultural knowledge learned in the United States.
