The Sectors Where Engineers are Found

by Fred Nwaozor > This classification captures the major ecosystems or sectors where professional engineers operate. What matters is how their roles shift in focus across these sectors, even though the core engineering principles remain the same. 1. Government (Policy formulation & implementation) In government, engineers function less as hands-on designers and more as technical decision-makers. They contribute to national development by shaping policies, regulations, and standards that guide engineering practice. For example, a civil or telecom engineer in a regulatory agency may help draft infrastructure policies, evaluate national projects, or enforce compliance with safety and quality standards. Their authority ensures that engineering decisions align with public interest; balancing cost, safety, sustainability, and long-term impact. Here, engineering judgment influences what gets built, how it is built, and whether it should be built at all. 2. Academia (Teach...

Ihejirika's Giant Steward and Nigeria Immigration Service

by

Fred Nwaozor

The last time I checked, there was need to celebrate and grant a standing ovation to an icon in the Nigeria’s public service who recently took a heroic bow having served gallantly.

In the disciplined corridors of the Nigeria Immigration Service (NIS), where vigilance meets patriotism and duty defines identity, one name stands tall – Casmir Chukwuemeka Ihejirika.

His career reflects the creed of the Service; guarding the nation’s gateways with honour, courage, and commitment. This can be strongly attested to by anyone who has come across his person.

Born on 26th November 1965, Ihejirika hails from Umuduruonyeka, Umuòkpò, Nkume of Njaba Local Government Area in Imo State. From these humble roots emerged a public servant whose life’s work became inseparable from national service.

He joined the NIS on 24th September 1991 as an Assistant Superintendent of Immigration (ASI), bringing with him youthful exuberance, intellectual depth, and an unshakable sense of purpose.

At the age of 60, on 26th November 2025, he meritoriously bowed out of service as a Deputy Comptroller of Immigration (DCI), having devoted 34 years to strengthening Nigeria’s border security and migration management architecture.

Ihejirika entered the Service armed with a Bachelor of Science degree in Biochemistry from the prestigious Imo State University (IMSU), a foundation that sharpened his analytical thinking and problem-solving skills.

Ever committed to personal growth and institutional relevance, he later earned a Master’s Degree in Mass Communication from the University of Uyo, Akwa Ibom State, in 2012, enhancing his strategic communication and leadership capacity.

Between 1992 and 2007, he served as a Border Control Officer at the Sèmè Border in Lagos State and later at the Sokoto borders, where vigilance, resilience, and sacrifice were daily demands rather than occasional expectations.

From 2011 to 2013, he supervised Offshore and Inland Waterways Migration Management Operations in Akwa Ibom State, bringing structure, coordination, and professionalism to a complex operational environment.

He further distinguished himself as Supervisor of the Oron/Ibaka Border Control Post from 2013 to 2014, and later as Border Patrol Corps Commander in Sokoto State (2015–2020), a role that tested leadership under pressure and rewarded excellence in command.

Beyond field operations, Ihejirika made enduring contributions to institutional development, serving as a Member of the Technical Working Groups on Curriculum Development and Review of the NIS Training Strategy Implementation (2020–2023).

In 2023, he was part of the Learning Management System (LMS) Development for the IOM-implemented NIS-TSI, became an IOM-certified Training Focal Person, and served as National Team Leader for the Nigeria–Kenya Pier-to-Pier Knowledge Exchange Programme in Nairobi.

His professional standing was further elevated when he became a Fellow of the Army War College, Nigeria, and a Fellow of the Chartered Institute of Public Diplomacy and Management (CIPDM) –recognitions that underscore strategic depth and diplomatic competence.

In 2024, he contributed to regional cooperation as a Member of the Drafting Committee for the Tri-Lingual Glossary Document aimed at enhancing cross-border communication between Nigeria and the Niger Republic, and in 2025, he served as a Training Facilitator at the Nigeria Immigration Training School, Kano.

His service journey cut across Lagos, Sokoto, Akwa Ibom, Kaduna, Niger, Kano, Imo State Commands, the Service Headquarters in Abuja, and culminated in his role as Comptroller of Immigration, Imo State Command, a position he held with distinction until 2024.

An accomplished officer and thinker, DCI Casmir Ihejirika is also the author of ‘Migration and The Nation’, a fitting intellectual legacy. This was done to fully educate the public on the essence of Immigration Service in not just Nigeria but any country of note.

Happily married with children, his story echoes a simple line befitting his years of service: “He stood at the gates, not for glory, but for country; and when duty called, he answered – every time.”

To this end, it’s no doubt lofty and laudable to give a resounding accolade to this gentleman of note who has written his name in gold in the Nigeria’s public space. Think about it.
