Non-Immigrant Visas
Diplomatic and Official Visas
With the exception of a Head of State or Government who qualifies for an A-1 visa regardless of the purpose of his or her visit to the United States, the type of visa required by a diplomat or other government official depends upon his or her reason for entering the United States.
To qualify for an A-1 or A-2 visa, the individual concerned must be traveling to the United States on behalf of his or her 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 whether or not the applicant qualifies for an A visa; the particular duties or services to be performed must also be of an inherently governmental character or nature. Local government officials representing their state, province, borough, or other local political entity do not qualify for "A" visa status; they require B-1/B-2 visas.
Government officials traveling to the United States to perform non-governmental functions of a commercial nature or traveling as tourists require the appropriate B visa.
Qualified A visa applicants traveling to the United States for assignments of less than 90 days will be issued visas annotated "TDY" (temporary duty).
Important note: Foreign officials who intend traveling to the United States on official business must obtain an "A" visa prior to their entry. They cannot travel on tourists' visas, or visa free under the Visa Waiver Program.
Immediate family members are defined as the spouse and unmarried sons and daughters of any age who are members of the household. Partners who are recognized as the principal alien's dependant by the sending government, while not eligible for derivative A visas, may apply for B-1/B-2 visas, if otherwise qualified. B-1/B-2 visa applicants are required to pay visa application fees.
