ABSTRACT
This chapter claims that, due to difficulties in investigating issues which result in a crossing of the borders of domains and disciplines, the development of interdisciplinary research is trapped in problems of concepts' definitions, research methodologies and data gathering. It focuses on how keeping an interdisciplinary perspective could help to both cover literature gaps and improve our understandings of some neglected migration-related phenomena and inter-cultural dilemmas entailing consequences for both states and societies. The chapter also focuses on the developments of the discipline of the Sociology of International Relations and the increased attention paid to international migration in the branch, mainly in the area of Security Studies. It provides an examination of the state of the art on both Diaspora and Immigrants' Transnationalism in Security Studies. The chapter suggests pragmatic approaches to the usage of terminologies.
