Important Notice

Do not pay a visa processing fee through this site without contacting the American Institute in Taiwan (AIT) Consular Section first, as it will not be refunded.


A-1, A-2, C-3, and G-1 through G-4 visas may be issued to diplomats and other government officials for official travel to the United States. Generally, the class of visa required by a diplomat or other government official depends upon their purpose of travel to the United States. There are very specific requirements which must be met by applicants in order to qualify for A, C-3, G or NATO visas under U.S. immigration law.

Depending on the purpose of your intended travel and other facts, you may also qualify for other type of visa classification.  Please read the below information and the Common Nonimmigrant Visas page to determine your visa classification.

Note: Employees of the Taipei Economic and Cultural Representative Office (TECRO) may not receive A or G nonimmigrant visa classification.  Representatives of Taiwan employed by TECRO currently receive E nonimmigrant visas and are admitted to the United States in E-1 nonimmigrant classification.  TECRO employees and their dependents as well as Taiwan representatives should contact Taiwan Council for U.S. Affairs (TCUSA) regarding their visa applications for official travels. 

Visa Descriptions and Qualifications

A-1, A-2 Visas
A visas are generally issued upon presentation of a diplomatic note from the appropriate host country office or foreign mission.

Diplomats and other foreign government officials traveling to the United States to engage solely in official duties or activities on behalf of their national government must obtain A-1 or A-2 visas prior to entering the United States. They cannot travel using visitor visas or under the Visa Waiver Program. If an A-1 or A-2 visa applicant is coming to the United States for an assignment that is to last less than 90 days, the visa is annotated "TDY." Normally, the personal interview requirement for bona fide A-1 and A-2 visa applicants who are citizens of, or accredited to, the host country is waived. However, there may be circumstances within which the consular officer will ask for an interview.

A-3 Visa
Issued to the attendants and personal employees of persons in A-1 or A-2 status.

C-3 Visa
Issued to an accredited official of a foreign government intending to proceed in immediate and continuous transit through the United States on official business for that government. Members of the immediate family, attendants, servants, or personal employees of such an official may also be issued C-3 visas when appropriate.

G-1 Visa
Issued to members of a permanent mission of a recognized government, to an international organization, regardless of rank, and to members of their immediate families. G-1 visas are also issued to the mission's secretaries, chauffeurs and custodial employees, except domestic employees, who are issued G-5 visas.

G-2 Visa
Issued to representatives of a recognized government and to members of their immediate families traveling to the United States temporarily to attend meetings of a designated international organization. G-2 officials may represent their governments at the United Nations (UN) General Assembly or as TDY officers to that country's mission to the international organization. G-2 visas may be issued to military officers who are assisting the UN Secretariat with peacekeeping matters. Family members may also be issued G-2 visas.

G-3 Visa
Issued to representatives of non-recognized or non-member governments, regardless of rank, and to members of their immediate families. G-3 visas should also be issued to representatives of such governments so as to participate in temporary meetings of designated international organizations (e.g., a meeting of the UN General Assembly and Security Council).

G-4 Visa
Issued to personnel of any rank who are proceeding to the United States to take up an appointment at a designated international organization (including the United Nations). Members of their immediate families may also be issued G-4 visas, except their domestic employees, who are issued G-5 visas. Officers and employees of designated international organizations, who are not assigned in the United States, may be accorded G-4 classification if they intend to transit the United States. The number of entries should be limited to the official request. G-4 visas may also be issued to personnel of any rank on the payroll of a designated international organization proceeding to the United States on behalf of that organization.

G-5 Visa
Issued to the attendants and personal employees of persons in G-1 through G-4 status. Note: If a Legal Permanent Resident (LPR) were to be employed by a foreign mission in the United States, he or she would be eligible for A visa status if he or she would be willing to surrender his or her permanent residence card.
