G-2 visa is required if you are a representative of a recognized government temporarily traveling to the United States to attend meetings of a designated international organization.
G-3 visa is required if you are a representative of non-recognized or non-member government temporarily traveling to the United States to attend meetings of a designated international organization.
G-4 visa is required for individual personnel traveling to the United States to take up an appointment at a designated international organization, including the United Nations. Please see Visit the Department of State Bureau of Consular Affairs website to learn more about G visas.
