The H1B visa can also be allocated to fashion models of distinguished merit and ability (H-1B3 Visa), or to the person providing service related to the Department of Defense (H-1B2).
In addition to the specialty occupation requirement, the intending H-1B2 must show that a bachelor’s or higher degree, or its equivalent is required to perform duties, and that the cooperative research and development project (or a co-production project) is provided for under a government-to-government agreement administered by the U.S. Department of Defense
