OIA is focused on keeping Americans safe at home and abroad by ensuring criminals are held accountable for their actions regardless of where in the world they may be hiding. As DOJ’s nerve center for international criminal law enforcement coordination, OIA’s efforts in pursuit of this aim are carried out through five principal works streams: extradition and removal of fugitives, transfer of sentenced persons, international evidence gathering, providing legal advice to DOJ leadership and prosecutors, and international relations and treaty matters.
- Extradition and Removal of Fugitives: OIA plays a central role in apprehending and returning fugitives to justice so that they may be held accountable for their crimes. Using all the legal tools at its disposal —extradition, deportation, and other lawful measures — OIA works with domestic and foreign partners to extradite or lawfully remove criminals sought for prosecution in the United States or abroad for a wide variety of offenses, including violent crime.
- International Prisoner Transfer: OIA adjudicates applications from sentenced persons to return to their home countries to serve their term of imprisonment. In so doing, OIA meets the obligations of the United States under bilateral treaties and multilateral conventions concerning the transfer of sentenced persons.
- International Evidence Gathering: Through a vast network of international relationships and treaties, OIA obtains evidence located abroad that is essential for successful U.S. prosecutions, seeks enforcement of U.S. asset forfeiture orders abroad, and arranges return of assets to the United States. OIA also obtains evidence in the United States on behalf of foreign criminal investigators, thereby enhancing our foreign partners’ ability to interdict criminal threats abroad before they reach our shores.
- Legal Advice to DOJ Leadership & Prosecutors: OIA is DOJ’s primary expert on international criminal matters, providing legal and strategic guidance to DOJ leadership with respect to the Department’s present and future challenges in international criminal law enforcement. OIA attorneys also provide advice to federal and state prosecutors regarding novel and complex legal issues arising in litigation and stemming from the international aspects of their prosecutions.
- International Relations and Treaty Matters: On matters affecting DOJ’s international law enforcement mission, OIA attorneys negotiate and provide expert counsel regarding treaties and other agreements. OIA attorneys also represent DOJ in a multitude of multilateral fora, where they formulate law enforcement strategies to promote the U.S. government’s law enforcement interests.
