Administrative Justice and Citizen Rights in Nigerian Immigration Service Operations

This study investigates the extent to which the Nigerian Immigration Service (NIS) upholds administrative justice and respects citizen rights in the processing of immigration-related services. The NIS, operating across all geopolitical zones, has been subject to numerous complaints of procedural delays, discriminatory treatment, and extortion at immigration offices and border checkpoints. Employing a survey design, data were collected from 300 passport applicants, visa seekers, returning Nigerians, and immigration scholars across Lagos (South West), Abuja (North Central), and Kano (North West) offices. Descriptive statistics and thematic analysis are applied to quantitative and qualitative data respectively. The Administrative Justice Theory, premised on procedural fairness, proportionality, and legal accountability, provides the conceptual framework. Findings reveal that a significant proportion of respondents experienced unjustified delays, payment of unofficial fees, and discourteous treatment by immigration officers. Delays are concentrated in passport and visa processing due to inadequate staffing and poor digital infrastructure. The study recommends the full digitisation of immigration service processes, mandatory customer service training for officers, and the establishment of an independent complaints and redress mechanism within the service. These reforms are situated within Nigeria's broader commitment to improving governance and human rights compliance.
