In 2018 the US State Department established the following definition to answer the question:
"What is a goodwill ambassador?"
"Goodwill ambassadors are prominent Americans who represented the United States overseas through State Department programs. Today, these individuals are more commonly referred to as Cultural Ambassadors, Sports Envoys, or Arts Envoys. In these State Department Exchange Programs, Americans can create long-lasting ties between the United States and other countries. Through demonstrations, clinics, and casual interaction, they forge people-to-people ties to build mutual understanding of ideals and culture."
