The Office of International Affairs provides advice and assistance on international criminal matters to the Attorney General and other senior Department of Justice officials, the Criminal Division and the Department's other legal divisions, the U.S. Attorneys offices, and state and local prosecutors. OIA coordinates the extradition or other legal rendition of international fugitives and all international evidence gathering. In concert with the State Department, OIA engages in the negotiation of new treaties, conventions, and other agreements on international criminal matters. OIA attorneys also participate on a number of committees established under the auspices of the United Nations and other international organizations that are directed at resolving a variety of international law enforcement problems, such as narcotics trafficking, organized crime, cyber-crime, corruption, terrorism, and money laundering. OIA maintains permanent field offices in Rome and Mexico City, and recently opened an office for Central America in San Salvador. OIA also works closely with a Criminal Division representative in Brussels, and has exchange programs with the Justice Ministry in France and the Home Office in the United Kingdom. An OIA attorney normally serves as the general counsel to the U.S. National Central Bureau (the U.S. office for Interpol).
