This paper describes an experience for professionals based on an intensive 1-week language immersion course that has been offered in Akron, Ohio and Denver, Colorado. The course has been designed for professionals at the intermediate level in French and Spanish. The course requires that participants have acquired the basic grammatical structures in the target language. The course is a modified version of immersion. Unlike traditional content-based instruction, this immersion experience is based on situations and language functions that can be tied to business and other professional topics. The program is an intensive language experience in which authentic activities and materials are used in order to prepare the professional for specific social contexts in which to use the language, such as business negotiation or a technical training session in Mexico or France. The description of the immersion course for professionals includes a rationale, course objectives, thematic/topical organization of the course, and the procedures. Appended materials include examples of activities, partial syllabi, and a resource list. (JL)
