Overview
Other NATO officials not classifiable under NATO-1 through NATO-3.
The NATO-4 is a US visa for NATO officials who do not fit the NATO-1, NATO-2, or NATO-3 categories, covering officers, employees, contractors, and advisors on authorized NATO missions under the 1951 Ottawa Agreement and the Paris Protocol.
Admission is granted for Duration of Status (D/S) with no fixed end date, tied to the NATO assignment and renewable while it continues. MRV and reciprocity fees are waived. There is no PR pathway, work is restricted to NATO duties, and dependents may seek work authorization via Form I-566.
This visa is ideal for accredited NATO personnel posted to the US whose stay is bound to an official Alliance mission rather than independent employment.
