This paper presents a comprehensive comparative analysis of the legal structures governing nationality laws and labour migration in the UAE and the UK, shedding light on their respective economic repercussions. In examining these legal systems, the study delves into the UAE’s distinctive kafala system, which tightly binds migrant workers to their sponsors, and holds it in contrast to the UK’s point-based immigration system based on rules and regulations. Despite these differences, both nations have witnessed tangible benefits from labour migration, including increased productivity, the creation of new jobs, and economic diversification. However, this study highlights the lack of discernible correlation between changes in GDP and alterations in immigration laws within the UAE and the UK. The implications of these findings are far-reaching, underscoring the imperative for effective legal frameworks to optimise the economic gains derived from labour migration. Policymakers stand to gain valuable insights for addressing wage disparities and promoting social integration through the knowledge derived from this research, enabling them to formulate policies that maximise the benefits of labour migration  while minimising its drawbacks. To fully understand the long-term effects of labour migration on economic growth, it is crucial to examine the experiences of various migrant groups and the efficacy of various policies and interventions. Informed by these examinations, policymakers can then develop legal frameworks that facilitate labour migration and contribute to sustainable economic development in the UAE and the UK.
