The overriding consensus in existing mainstream literature in migration study is that international migrants may in some specific way constitute a security threat to destination state/s. Even though this resembles very plausible, the author in this research has proceeded in a different way so as to unveil the alternative scenario. Accordingly, analysing the security threats accruing from migrants returning home will be the main tenet of this research. In doing so, the researcher has tried to approach the problem from sociological, security, migration, legal and economic points of view. As a result, this research will be useful for academicians, government authorities, researchers working in the area as well as for students.
