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...

Nigerians lament over new US' Visa Policy on Nigeria, others

Frank Musa
Nigerians, in their numbers, have continued to lament over the recent single-entry visa policy imposed on the applicants from Nigeria, among other African countries, by the United States' (US') President, Donald Trump.

It could be recalled that a few days ago, the US Government announced sweeping changes to its non-immigrant visa policy for Nigeria, Ghana, Cameroon, and Ethiopia, reducing the duration and increasing the conditions under which most travellers from those countries can enter the US.

The US Department of State disclosed that nearly all non-immigrant and non-diplomatic visas issued to citizens of the four countries would now be single-entry and valid for only three months rather than the usual multiple-entry, five-year validity.

It claimed the measure was part of a "global reciprocity realignment", a sharp shift from previous visa terms, which often allowed for multiple entries within two years or more.

However, the Nigeria's Government has denied reports that it only offers single-entry e-visas for three months to US citizens, disclosing Nigeria continued to offer five-year multiple-entry visas to US nationals.

The report stated that the US government's claim of reciprocity as the reason for its current visa policy towards Nigeria did not accurately reflect the actual situation.

On the other hand, the US citizens can reportedly get visas of up to a year in Cameroon, and similar duration in Ethiopia, though the authorities in these two countries were yet to comment as at the time of filing this report.

On their part, Ghana's government said the West African nation has issued more than 28,500 multiple entry visas to US citizens in this year alone.

As we count down the days after the announcement of the stringent measure from the Trump's controversial administration, Nigerians - both home and abroad - have continued to express worry over what their fate entails.
