As globalization increases, dual citizenship has become more common,
raising legal and policy concerns about national identity, security, and
governance. This article compares how Nigeria and the United Kingdom
(UK) approach nationality and dual citizenship. It also examines the history
and legal frameworks of both countries, highlighting inconsistencies and
policy challenges. At the same time, it explores how dual citizenship relates
to economic growth, social inclusion, and legal certainty. By drawing on
international best practices and human rights principles, the study suggests
reforms that could make nationality laws fairer and more effective. A wellregulated approach to dual citizenship can strengthen institutions, improve
governance, and contribute to social and economic development in both
Nigeria and the UK.
