A-1 Visa

To qualify for an A-1 (or A-2 visa), you must be traveling to the United States on behalf of your national government to engage solely in official activities for that government.  The fact that there may be government interest or control in a given organization is not in itself the defining factor in determining if you qualify for an A visa; the particular duties or services that will be performed must be governmental in character or nature, as determined by the United States Department of State, in accordance with U.S. immigration laws. Government officials traveling to the United States to perform non-governmental functions of a commercial nature, or traveling as tourists, require some other appropriate visa, and do not qualify for A visas.
