If you are from a non-NATO country and the military education or training you are to receive is being provided at a U.S. military facility (service academy, fort, base, other military installation), you may qualify for an A visa regardless of the duration of the training. If the military training you are to receive is U.S. Government-sponsored or licensed but is not provided at a U.S. military facility, you may qualify for an A visa only if the period of training is less than 90 days. Note: NATO military personnel qualify for NATO visas. If you are a member of a national law enforcement or police agency coming to the U.S. on behalf of the national government for an official purpose (for example, to interview witnesses or in connection with an investigation), or coming for U.S. Government-sponsored training in connection with your official duties, you may qualify for an A visa.
