Governments and societies have an interest in knowing who is seeking access to their territories. The objective is to take measures that prevent access by those who are not authorized to enter, while facilitating speedy access for those who are. IOM assists governments in the development and implementation of migration policy, legislation and administrative mechanisms. To this end, IOM provides technical assistance and training for governmental migration managers on border management, visa systems, regulating entry and stay, and collecting and using biometric information.

Replacing irregular flows with orderly, regular migration serves the interests of all governments, and IOM can offer a broad range of programmes to counter trafficking and smuggling in human beings, from prevention to assisting the victims. IOM also implements programmes to facilitate the voluntary return and reintegration of displaced and stranded persons and other migrants, taking into account the needs and concerns of local communities.
