The Nigeria Immigration Service (NIS) is the government agency that has been charged with the responsibility of migration management in Nigeria.

Over the years, the NIS has witnessed series of changes since it was extracted from the Nigeria Police Force (NPF) in 1958. The Immigration Department, as it was known then, was entrusted with the core immigration duties under the headship of the Chief Federal Immigration Officer (CFIO) and the first to sit on that chair was in the person of Mr. EH Harrison. The department in its emergent stages inherited the Immigration Ordinance of 1958 for its operation. At inception, the department had a narrow operational scope and maintained a low profile and simple approach in attaining the desired goals and objectives of government. During this period, only the Visa and Business Sections were set up.
