This study examined the causes of irregular transnational inflow into Nigerian cities and its impact on criminalities. The study also discussed government measures to solve the problems, and hindrances against the moves. We collected primary data from twenty-two key informants, and secondary data from relevant books, journals, government documentaries, gazettes, and online publications. Data was content analyzed and interpreted thematically. Porous border, poor monitoring and corruption caused irregular entry into Nigerian cities. Irregular movement into Nigerian cities influences banditry, insurgency, clashes between, farmers and herders, and other criminalities. Government has increased its security budget, established operation safe corridor, presidential initiative on the North East, victims support funds, and so on to address the challenge but bad eggs, and tribalism subverted the efforts. The study concluded that land borders in the northern Nigeria are porous and expose northerners to more dangers.
