The international movement of traders, political envoys and soldiers is not new. But the late 20th century has seen an unprecedented growth in the activities of at least the first two groups. Increase in international mobility has been accompanied by growing interest in the psychological problems faced by these temporary migrants. It has prompted the development of specialised services for preparing expatriates before departure, and supporting them during their sojourn. Brussels is an example of an international centre with a huge expatriate population, and a demand for a dedicated telephone crisis service. This is the oldest, and one of the largest, services of this kind in Europe.
