The FBI's mission is to investigate violations of federal crime laws and support the law. It protects the United States by investigating intelligence and terrorist activities from foreign countries, and assists federal, state, local, and international agencies in the leadership and enforcement of the law, while performing its duties in response to the needs of the public and in fidelity to the Constitution of the United States.
After each FBI investigation, intelligence information is submitted to the appropriate U.S. attorney or U.S. Department of Justice official, who decides whether to authorize prosecution or other action. Five of the major areas affecting society have the highest priority: anti-atrocity, drug/organized crime, foreign counterintelligence, violent crime, and white-collar crime.

The number of specialized agents grows every year, and there are now more than 11,000 members. Most Special Agents are stationed in foreign countries, working in U.S. embassies as ambassadors' legal attachés, which the FBI calls itself: "LEGATS".
