The G-3 diplomatic Visa is a nonimmigrant Visa issued to representatives of unrecognized foreign governments, to enter into the U.S., and to work for an international organization such as International Monetary Fund, World Bank, etc. The immediate family members (spouse and children) of the principal G-3 Visa holders also qualify for G-3 Visas.
The G-3 Visa holders may perform only those duties that are related to the international organization. They should not use their entry for personal business or pleasure. Their dependents can work only after receiving permission from the U.S. Citizenship and Immigration Services (USCIS). Their dependents can take up a full-time of part-time course of study while on G-3 Visa.
