NW Services focuses on cultural exchanges for foreign exchange students of high school age in order to further that cause.  NW Services concentrates on high school  exchange students who will actually become a part of a community in the United States by living as a member of their host family: Eating meals, conversing, playing, and studying.  In short, these foreign exchange students are immersed in a new way of life; joining into the culture and community of their host family.  Significantly, this happens at a time in their lives when many people make their most long-lasting friendships. Once the foreign exchange student program ends, the NW Services exchange students then return to their home countries, bringing their new understandings and friendships along with them. It is then that cultural exchange has truly occurred
