RESUMO
Nigerian politicians accuse foreigners of contributing to the many security challenges in the country. As a result, the government of Nigeria securitised foreigners' immigration to justify its policy of land border closure in 2019, which it claimed was aimed at mitigating the security problems bedevilling Nigeria. This study analyses how Nigeria's national security is impacted by the securitisation of border governance and migration. Relying on the securitisation theory and qualitative methods based on focus group discussions, key informant interviews, and desk reviews of existing literature, it found that the securitisation of migration to establish strict border governance represents the interests of the political elite who have failed to address security challenges in Nigeria. The study concludes that government should de-securitise foreigners' immigration by addressing underlying domestic and external factors driving insecurity in Nigeria.
