The Federal Bureau of Investigation (FBI) is the primary investigative arm of the United States Department of Justice (DOJ), serving as both a federal criminal investigative body and a domestic intelligence agency. At present, the FBI has investigative jurisdiction over violations of more than 200 categories of federal crimes, making the FBI the de-facto lead law enforcement agency of the United States government. The motto of the bureau is "Fidelity, Bravery, Integrity."
The FBI headquarters is in Washington, D.C., and there are also 56 field offices located in major cities throughout the United States as well as over 400 resident agencies in smaller cities and towns across the nation, and more than 50 international offices, called "Legal Attachés," in U.S. embassies worldwide.
