Immersion in an international work environment with the educational value of the experience itself being the primary purpose. May or may not be for academic credit. Depending on the focus of the experience, it may be designated as interning, volunteering, service-learning, teaching, or just working abroad. Work abroad is sometimes used more narrowly to mean working for pay. By design, work abroad programs are temporary, lasting from a few weeks to two or three years. Educational work abroad is to be distinguished from career-related overseas assignments, permanent jobs abroad, and migration for gainful employment.
