International migration is an important component of a globalized world as well as a major aspect of international economic relations. As at 2017, about 258 million people lived outside their country of birth (International Labour Orgainization, 2018). In 2017, the Federal government of Nigeria declared that over 17 million Nigerians lived abroad (National Commission for Refugees Migrants and Interanlly Displaced Persons, 2017) as against 5 million Nigeria who lived abroad in 2009(Federal Ministry of Labour and Productivity, 2010)
High rates of unemployment, dissatisfaction with the general socio-economic conditions in the country, insecurity, bad governance, violation of human rights and political intolerance amongst others has increased the rate of labour migration from and within the country. This is peculiar to young and educated persons (Federal Ministry of Labour and Productivity, 2010).
