Introduction The rapid growth of globalization, plus astonishing advancements in information technology, has, in a sense, reduced the world to a global village. People can now travel frequently, safely and efficiently from one country to another for various reasons, including but not limited to military and corporate duty; business, trade and commerce; education and development; health and tourism; emigration and political asylum. This human migration is not only external. It is also internal. Citizens are moving from their area of birth to different parts of the country to live or do business. Internal conflicts, like the prevalent Boko Haram insurgency in the north-eastern parts of Nigeria, have turned some citizens into Internally Displaced Persons (IDPs). Conflicts have also forced citizens into refugee status outside their home countries. Put together, the huge increase in incidents of migration, externally and internally, all over the world has inevitably compelled growing and more urgent advocacy for the enfranchisement of citizens in the diaspora.
