Migration policy and decision-makers need to systematically collaborate towards sophisticated approaches that facilitate legal immigrants to be effectively integrated in labour markets and public administration processes. Latest ICT developments, which integrate Web 2.0 technologies, collaborative knowledge management systems, and semantic analysis technologies, allow participatory governance and citizen-generated policy making. This paper presents a collaborative migration policy-modelling centre, techniques, solutions and overall services for collaborative development of immigration policies, as well as for supporting related decisions. Keywords: migration information systems; collaboration; social computing; policy-making; participatory governance; security; privacy; public administration.
