Which of the following describes the role of H-3 workers?

The role of H-3 workers is best described by individuals participating in special education exchange programs. The H-3 visa category is specifically designed for foreign nationals who aim to come to the United States temporarily to receive training in a specific area, usually in a non-immigrant capacity related to special education and other fields. This type of visa allows trainees to gain skills and knowledge that they can apply upon their return to their home country.

The focus on education and training distinguishes H-3 workers from other visa classifications that may involve skilled labor or temporary employment in various roles. While the essence of their work may involve educational experiences and learning, it is not to be confused with skilled labor or technology roles, which are covered under other visa types.
