Trends in the planning and teaching of ethnic and foreign languages in the United States are examined, and the Language and Cultural Perspectives program of the University of Pennsylvania's Lauder Institute, a graduate program in management and international studies, is presented as illustration of a successful program of foreign language education that supports global language planning. Literature on immigrant (ethnic) languages, language planning and maintenance, and Title VI of the National Defense Education Act are reviewed, and the way in which the Lauder Institute program responds to some central issues is examined. Program structure is described briefly, noting the combining of language instruction and cultural immersion in an overseas study experience, continued instruction integrating language, business and culture, and summer internship opportunities.
