What characterizes the H-3 classification?

The H-3 classification is specifically designed for individuals who are coming to the United States to participate in a special education exchange visitor program that provides training. This visa aims to enhance the educational exchange by allowing foreign nationals to gain knowledge and experience in specific fields related to special education.

Unlike other classifications, such as short-term work for students or employment in seasonal jobs, the H-3 classification focuses purely on the educational aspect and the training involved. It does not lead to permanent residency for families, which is characteristic of other visa types. Therefore, B is the correct answer as it accurately addresses the purpose and function of the H-3 classification in the context of special education and training.
