DOJ International Investigations
Experienced Legal Representation for Investigations Involving the DOJ’s Office of International Affairs (OIA)
Our lawyers provide experienced legal representation for individuals and organizations that are facing international investigations involving the United States Department of Justice (DOJ) and its foreign counterparts. International criminal law enforcement investigations can pose substantial risks, and an informed, strategic, and proactive defense is critical for avoiding unnecessary consequences.

Individuals and entities targeted in international criminal investigations need highly experienced legal representation. These are high-risk matters that often involve senior law enforcement personnel in the United States and other countries around the world. In these cases, the U.S. Department of Justice (DOJ) frequently works with both domestic and foreign partners to gather evidence, substantiate charges, and pursue sweeping criminal prosecutions in U.S. federal court.
Our international criminal defense lawyers represent clients that are facing scrutiny from the DOJ and other agencies in the U.S. and abroad. We have extensive experience providing legal advice and representation regarding the international aspects of the DOJ’s law enforcement efforts. With a defense team that includes former DOJ prosecutors, we are able to provide valuable assistance and strategic guidance for all matters involving domestic and foreign authorities.
The OIA Coordinates the DOJ Criminal Division’s Cooperation with International Law Enforcement Agencies
The DOJ’s Office of International Affairs (OIA) coordinates the Department’s law enforcement efforts with foreign governments and foreign officials. It maintains international relationships with its counterparts in countries around the world—including (but not limited to) other United Nations and INTERPOL member nations.
Among other things, the OIA works with its international partners in foreign law enforcement to:
- Secure foreign evidence
- Detain individuals in foreign countries
- Pursue extradition requests
Foreign relations play a critical role in the DOJ’s international law enforcement efforts. From efforts to substantiate charges under U.S. federal statutes to efforts to lawfully remove criminals sought for prosecution in the U.S. courts, the DOJ relies heavily on its vast network of foreign law enforcement partners when necessary. As a result, international investigations can be both extremely high-risk and extremely complex, and this makes it imperative for targeted individuals and entities to have experienced international defense counsel.
International Investigations Involving the DOJ Can Target a Wide Range of Alleged Crimes
Our lawyers represent clients that are facing international investigations targeting all types of federal crimes. This includes (but is not limited to) DOJ international investigations targeting:
Money Laundering and Financial Crimes
Multiple task forces within the DOJ target international money laundering and other cross-border financial crimes. These crimes carry substantial penalties, and they are priority enforcement areas for both federal and state prosecutors. While international investigations are often triggered by financial reporting anomalies, the DOJ and its international partners can gather additional evidence through various means.
Organized Crime
Targeting organized crime groups is a priority enforcement area as well. This includes drug cartels and other criminal organizations. From Mexico City to other major cities around the world, our lawyers provide legal and strategic guidance for leaders of alleged criminal organizations worldwide.
Transnational Crimes
The DOJ’s OIA assists with obtaining transactional evidence for investigations spanning across the globe. In today’s world, transactional crimes can take numerous forms (including cybercrime and intellectual property theft, among many others), and law enforcement authorities around the world are doing their best to keep pace. Along with the DOJ, the Federal Bureau of Investigation (FBI) is actively involved in investigating transnational crimes as well, and the FBI has more than 250 agents stationed worldwide for international operations, and its law enforcement attaché program covers more than 180 countries.
Violent Crimes
The DOJ’s OIA works with its foreign counterparts to pursue extradition of violent criminals sought for prosecution in the U.S. as well. This includes pursuing extradition of individuals wanted for murder, sexual assault, and other serious violent offenses.
International Relations and Treaty Matters
Along with these types of matters, the DOJ also works with law enforcement authorities in other countries in connection with various other international relations and treaty matters. This includes matters such as:
- Extraterritorial jurisdiction matters
- Matters involving mutual legal assistance treaties
- Extradition to the U.S. and foreign countries
If the DOJ is targeting you or your organization in an international investigation involving any allegations under U.S. federal law, our lawyers can provide the advice and representation you need. While there are no guarantees, we have a proven record of success in these cases, and we have resolved the vast majority of our clients’ investigations without criminal charges being filed.
