Migration has taken place throughout human history and continues to do so in the 21 st century. In many recent instances, states that are destination of migration flows framed migration as a security issue, i.e. a threat to their citizens' livelihood, safety, and cultural identity. Discourses that securitize migration, thus criminalising immigrants, are not unique to the US and the EU, nor to South-North migration: they pertain to South-South migration as well. This article draws attention to a case of migration and border securitisation from the global South: the one concerning India-bound informal migration originating from Bangladesh. This, incidentally, is also the country of origin of large numbers of migrants that have made their way to Europe during the last decade. This article asks what are the consequences of a securitized approach in the framing and managing of borders and migration, and whether such consequences are worth or at all affordable to the countries involved in the securitisation. The article assesses the potential impact that securitized discourses have on Indo-Bangladeshi relations, as well as on the domestic politics of India and Bangladesh. It reviews the processes of the securitisation of the India-Bangladesh border and the criminalisation of the Bangladeshi migrants in India's contemporary domestic politics with reference to recent (2019)(2020)(2021) events and current affairs.
