NATO-1 Law and Legal Definition

A NATO–1 visa is a nonimmigrant US visa available to permanent representatives of NATO, their staff members and their immediate relatives, for temporary stay.

Under the North Atlantic Treaty Organization (NATO), certain representatives and staff from member countries can enter the US on temporary visas. Once a NATO visa is acquired, the applicants are exempt from routine immigration inspections and documentary requirements.

NATO officials who intend to travel to the US on official business must obtain a "NATO" visa prior to their entry. They cannot travel on tourist visas, or visa free under the Visa Waiver Program.

‘Immediate relatives’ includes only the spouse of the representative and his unmarried sons and daughters of any age. Therefore an unmarried partner will not be eligible for a G or NATO visa even if he/she could be proved to be the principal applicant’s dependent.
