The present study considers fourteen of the principal regional consultative processes on migration, spanning most regions of the globe. Based primarily on interviews with government officials and other actors involved in these processes, the study asks what impacts regional consultative processes on migration have had on migration governance and on fostering greater confidence in inter-state cooperation on migration. This report sets out with a broad definition of migration governance. It identifies three distinct phases of the governance processes and analyses the contributions regional consultative processes on migration have made to each of these. The study then proceeds to draw general lessons and recommendations from the experiences of different processes in terms of their working style and focus.
