A NATO-6 visa is a non-immigrant US visa issued to a member of the civilian component of the NATO and their immediate family. These also consist of members of the civilian component attached to or employed by an Allied Headquarters under the Protocol on the Status of InternationalMilitary Headquarters and their immediate relatives. Admission to the US may last till the duration for the employment or assignment with the NATO in the US is completed.
‘Immediate relatives’ includes only the spouse of the representative and his unmarried sons and daughters of any age. The application procedures are the same as for the principal applicant.
To acquire a non immigrant visa, the ‘alien’ must submit a NATO visa application to a US consulate authorized to issue nonimmigrant visas. Although the consulate does not usually require an interview they can request for one. In addition, visa applicants are exempt from the fingerprint scan requirement.
NATO -6 visa holders are exempt from entry into the US-VISIT program
