The commitment of American host families is vital to FLEX’s success. It is also vital to the realization of U.S. foreign policy goals by fostering communication with the youth of key countries. By becoming part of an American family, FLEX students gain a well-rounded understanding of the United States while learning to be more reflective about their own country. Meanwhile, without the need for a passport, families gain an appreciation of another culture. It is a unique opportunity for both sides to learn about each other based on personal, direct interaction and sharing.
