title: Immigration history and the future of international migration.
abstract: "International migration must be understood as a permanent phenomenon rather than as a temporary movement.  In this article, the author proceeds from the premise that in appreciating the relation between the past and the present, we may be able to draw on 'lessons of the past' to modify our definition and perception of current problems and to analyze possible policies and decisions.  The article is divided into several sections, historical changes within migration patterns including different categories of migrants, various phases within the migration process in recent history, theoretical considerations in analysis, distinct types of immigration policies pursued by various states, and current and possible future trends."
