[Excerpt from authors]This paper focuses on some of the challenges and the opportunities created by migration of nurses, specifically focusing on the issue of return. Increases in migration of nurses over recent decades has been generating grave concern, especially in developing countries, where, when the migration is permanent, the loss of skilled health professionals can seriously weaken health systems. Nurse migration also creates opportunities, however, including those created by return. Nurses who return home after a period of working abroad are often equipped with new skills and work experience. They may be able to serve as an enriched resource for health services, helping strengthen health systems and thus health in general in their countries of origin.
