With a porous border, no nation can check influx of criminals or even terrorists.

To make the border tighter, the Nigerian Government has unveiled a new immigration policy known as "Immigration Regulations 2017".

The policy is expected to regulate the entry of immigrants and address other trans-border crimes.

The Minister of Interior, Abdulrahman Dambazau, while unveiling the document on Monday in Abuja said it would also fast-track the ease of doing business in Nigeria.

He explained that the "Immigration Regulations 2017" seeks to implement the Immigration Act, 2015 and provide legal support for the reforms.

Dambazau said the new regulation would replace the old and outdated Immigration Act of 1963, which could not take care of modern realities such as terrorism and technology.

"The objective of this new Immigration Regulations 2007 is to provide the legal framework for the effective implementation of the Immigration Act, 2015 and consolidate existing immigration regulations.

"This new document therefore replaces the outdated Immigration Act of 1963," he said.

The Minister explained that the new document empowers the Nigeria Immigration Service (NIS) to register all foreigners, protect the borders, enhance internal security and attract foreign investors.

With the policy in place, the NIS would be empowered to register and monitor the entry and movement of foreign herdsmen who come into Nigeria.

According to him, this will also go a long way in checking herdsmen and farmers clashes.

Earlier, the Comptroller-General of NIS, Muhammad Babandede said that the “Immigration Regulations 2017’’ would positively change the operations of NIS in line with international best practices.

"The Immigration Act, 2015 made some profound provisions such as the establishment of migration directorate, dealing with issues bordering on smuggling of migrants and so on.

"I can assure you that with the Immigration Regulation 2017, NIS has been strategically positioned to combat all cases relating to transnational organised crimes,” he said.

According to him, NIS will be working with other security agencies like the Police, and INTERPOL to check trans-border crimes, human trafficking and arms smuggling.
