The Criminal Investigations Division coordinates all requests to the Bureau of Diplomatic Security from other Federal, state, and local law inforcement agencies for criminal investigative assistance overseas. The Criminal Investigative Liaison (CIL) Branch receives requests for assistance in investigations involving fugitive apprehensions, homicides, counterfeiting, money laundering, parental abductions, and numerous other criminal offenses.
Once a request for investigative assistance is received, the division contacts Diplomatic Security special agents assigned to U.S. diplomatic missions overseas. These special agents, in addition to their responsibilities of developing and implementing effective security programs at U.S. diplomatic posts abroad, serve as the primary liaison with foreign police and security services overseas in an effort to obtain support for U.S. law enforcement initiatives and investigations.
CIL receives approximately 1,000 requests for investigative assistance from other U.S. law enforcement agencies every year.
