Legal immigration is a complex, multi dimensional issue and the European Commission (E.C.) project ImmigrationPolicy2.0 (IMP2.0) [1] considered it as such by studying its legal, societal and policy implications before proposing and implementing holistic e-migration services contributing towards participatory governance and the harmonization of existing policies and practices. This paper outlines the IMP2.0 social, policy and legal research results which led to the design and implementation of targeted e-migration collaborative services by presenting the identified requirements and describing the services provided by the IMP2.0 web platform.
