Nigeria Immigration Service,NIS, has canvassed for adequate logistics and manpower to curtail the issue of illegal mining in the state.

Its Comptroller in Muhammad Ahmad, said this during a courtesy visit by the Chinese Ambassador, Dang Ying, to the State Command, saying all the foreigners that come in without valid travelling documents and permission to stay in the country were considered as illegal immigrants.

Ahmad also said the command had made efforts to curtail the issue of human trafficking, adding this had, however, been hindered by the porous state of the Nigerian border.

In his remarks, the ambassador said his visit was to strengthen the relationship between the Chinese government and the Nigeria Immigration Service.
