United States cultural exchange programs, particularly those programs with ties to the  Bureau of Educational and Cultural Affairs (ECA) of the United States Department of State, seek to develop cultural understanding between United States citizens and citizens of other countries. Exchange programs do not necessarily exchange one individual for another individual of another country; rather, "exchange" refers to the exchange of cultural understanding created when an individual goes to another country. These programs can be regarded as a form of cultural diplomacy within the spectrum of public diplomacy.
