Officers and men of the Nigeria Immigration Service should brace up for expected migration challenges from the crisis in Southern Cameroon.

They were asked to keep observing human rights and best practices for engaging the refugees and Nigerian returnees at the ports of entry.

Its Comptroller General, Muhammad Babandede gave the advice during a two-day working visit to Cross River, advising them to keep vigil and be sensitive to information, escalations and eventualities that may result from the ongoing situation in the Cameroon.

Babandede said Cross River was expected to play host to thirty thousand of the migrants and that three hundred had already been registered.

He spoke at a meeting with the Comptrollers of Cross River, Benue, Akwa Ibom and Taraba States, which border Cameroon from the south.

Babandede said some Nigerian returnees from Cameroon met the CGI at the Mfum border post to relate their experiences.

According to him, they also requests to be allowed to return with their trucks parked on the Cameroon side due to the temporary closure of the Nigeria-Cameroon border.

The United Nations Refugees Agency, UNRA, has projected that forty thousand displaced persons would migrate to Nigeria from Cameroon due to the recent crisis.

The crisis arose from a secession bid by English-speaking regions of Cameroon, including the South, resulting in protests, deaths, injuries and mass arrests of protesters.

Cross River shares boundary at different points with southern Cameroon.

The Mfum border post in Etung Local Government Area of the state was shut recently by the Cameroonian authorities as a result of the escalating crisis.
