The Federal Bureau of Investigation (FBI) is the primary law enforcement agency for the United States Government charged with the enforcement of over 200 categories of federal laws and providing cooperative services to other law enforcement agencies, such as fingerprint identification, laboratory examinations, and police training. The FBI's investigative functions fall into the categories of counter terrorism, foreign counterintelligence, civil rights, organized crime / drugs, violent crimes and major offenders, cyber and financial crimes.
Legat offices are staffed by FBI law enforcement professionals and support staff who work to stop foreign crime as far from American shores as possible and to help solve international crimes that do occur as quickly as possible. Legat offices work with law enforcement and security agencies in their host country to coordinate investigations of interest to both countries. The rules for joint activities and information sharing are generally spelled out in formal agreements between the United States and the host country.
