Student and teacher exchanges between countries and within the domain of informatics to support health are considered. The availability of guidance appears to be institution-wide not country-specific. It is also not related to the discipline within which the exchange will occur. Concerns and issues are considered here in order for potential participants to prepare better for such exchanges. The observations made will be of interest to the administration of the organisations within which exchanges may occur. The investigation of this topic was delphic and pragmatic rather then exhaustive. The author bears no liability for situations that occur in specific locations.
