The A-Visas are some of the best visas to obtain for non-immigrants with the desire to live and travel in the United States. It is well known as the diplomatic visa or official visa, and is especially purposed for officials from other countries or diplomats who wish to enter the United States.
Because there are several levels of diplomacy and different categories of government officials, the United States issues three different types of A-Visas:
A-1 Visa
A-1 visas are issued to diplomats, consular offices, public ministers. Family and relatives of these officials are also accepted under A-3 status. The A-1 visa allows foreign visitors to enjoy a variety of freedoms in the United States.
A-2 Visa
A-2 visas honor reciprocity for foreign government officials and foreign employees who are accepted by the Secretary of State. This visa is also issued to military officials who are traveling under circumstances that are not related to NATO policy. Immediate family is also accepted under A-2 status.
A-3 Visa
A-3 visas are granted to the employees, servants and attendants of officials and employees who hold an A-1 or A-2 visa. The family of these visa holders are also accepted under A-3 status.
