An ad hoc committee will organize a conference to examine the effects of changes in selected industrialized countries’ treatment of temporary and permanent immigrants with advanced training and skills, especially in the sciences, engineering, and software development, in an effort to understand the effects of the policy changes, in relation to other factors, on entry and retention and domestic labor markets and educational patterns. The conference will also compare these countries' administrative mechanisms (e.g., commissions and point systems), methods of integrity assurance, and data collection and evaluation. The committee will develop the agenda, select and invite speakers and discussants, and moderate the discussions. An individually-authored workshop summary will be prepared by a rapporteur.
