The intent of the requirement is to have the home country benefit from the Exchange Visitor's experience in the United States. Exchange Visitors come to this country for a specific objective such as a program of study or a research project. The requirement is intended to prevent a participant who is subject from staying longer than necessary for the objective, and to ensure that he or she will spend at least two years in the home country before coming back to the United States for a long-term stay. If a participant is found subject to the requirement, their J-2 dependents will be subject as well.
H includes temporary workers, trainees, and their dependents.
L includes intracompany transferees and their dependents. The A classification includes your home government's diplomats and representatives to the United States government, and their dependents. The G classification includes your government's representatives to international organizations, such as the United Nations, and their dependents. You are subject to the Requirement . . . If you have ever been subject to the requirement in the past, and have neither obtained a waiver nor fulfilled it by spending two years in your country, it still holds even if a more current Form IAP-66 reflects no basis for such a requirement.
