For 60 years, AFS Intercultural Programs has been leading international high school student exchange. AFS was founded by volunteer American Field Service ambulance drivers from World Wars I and II who believed — as AFS believes today — that the way to build a more just and peaceful world begins when people from different countries meet, learn about each other, and begin to understand each other. AFS is a 501(c)3 nonprofit organization and is largely a volunteer-driven organization, with more than 5,500 U.S. volunteers and 30,000 worldwide.
