    If you’ve ever wondered how the Nigeria Immigration Service (NIS) is structured, here’s a simple and clear guide to understanding their official ranks and symbols. Like other paramilitary agencies, the NIS operates a structured hierarchy made up of senior officers (commissioned ranks) and junior officers (non-commissioned ranks). Each rank comes with an insignia that represents its authority and responsibilities.


    Commissioned Officers (Senior Ranks)


    These are high-ranking officers responsible for leadership, policy decisions, and supervising immigration operations nationwide.

    Rank Insignia/Symbol
    Comptroller General (CGIS) Coat of arms with laurel and crossed sword/staff
    Deputy Comptroller General (DCG) Two stars and coat of arms
    Assistant Comptroller General (ACG) One star and coat of arms
    Comptroller of Immigration Coat of arms only
    Deputy Comptroller Three stars
    Assistant Comptroller Two stars
    Chief Superintendent One star with stripe
    Superintendent One star
    Deputy Superintendent Two slim bars
    Assistant Superintendent I One slim bar
    Assistant Superintendent II One small star

    Non-Commissioned Officers (Junior Ranks)

    These are frontline officers handling border security, documentation, patrols, and enforcement.

    Rank Insignia/Symbol
    Inspector of Immigration Three chevrons
    Assistant Inspector Two chevrons
    Immigration Assistant I One chevron
    Immigration Assistant II Plain sleeve/No mark
    Immigration Assistant III Recruit, no insignia

    Final Notes:

    • The Comptroller General is the highest-ranking officer in the NIS.

    • Insignias often appear on shoulder epaulettes or uniform sleeves.

    • Promotions are determined by years of service, qualifications, and merit.

    • This ranking system is in line with other paramilitary agencies like Customs and Civil Defence.

    Understanding these ranks and symbols will help anyone preparing for NIS recruitment, promotions, or simply seeking to understand how Nigeria's immigration officers are organized.
