Border control

Border controls are measures taken by a country to monitor or regulate its borders. Border controls are put in place to control the movement of people, animals and goods into as well as out of a country. Specialized government agencies are usually created to perform border controls. Such agencies may perform various functions such as customs, immigration, security, quarantine, beside other functions. Official designations, jurisdictions and command structures of these agencies vary considerably. [Border control. Wikipedia]
