Mario Mancuso, P.C. leads the Firm’s International Trade and National Security practice. A former senior member of the President’s national security team, Mario provides strategic and legal advice to companies, private equity sponsors, and financial institutions operating or investing across international borders.

Since his return to private practice, Mario has been consistently recognized as a leading international practitioner by Chambers Global: The World’s Leading Lawyers for Business and Chambers USA: America’s Leading Lawyers for Business. Named an “International Trade MVP” by Law 360, he is a leading advisor on matters involving the Committee on Foreign Investment (CFIUS), economic sanctions (OFAC), export controls (ITAR, EAR), and the Foreign Corrupt Practices Act (FCPA), earning praise from boards, CEOs and senior executives for his holistic and "very strategic" approach. Clients say he is “thoughtful, responsive and cuts right to the heart of the issue,” and enthusiastically applaud his work as "a highly skilled technician of the law and commercially savvy advisor."

In particular, he served as a senior CFIUS decision-maker, helped draft and implement regulations for the Foreign Investment and National Security Act of 2007 (FINSA) and reviewed hundreds of CFIUS transactions as a regulator. As Under Secretary, he also participated in National Security Council decisions regarding economic sanctions (OFAC) programs; led the bilateral strategic technology dialogues for the United States, including the U.S.-China High Technology and Strategic Trade Working Group, the U.S.-India High Technology Cooperation Group, and the U.S.-Israel High Technology Forum; and led and managed an agency of approximately 400 career civil servants in offices throughout the United States and in China, India, Hong Kong, the UAE and Russia. Mario’s extensive government experience includes:

  • U.S. Under Secretary of Commerce, Industry and Security (confirmed unanimously by the U.S. Senate)
  • Deputy Assistant Secretary of Defense, Special Operations and Combating Terrorism
  • Special Counsel, Office of the U.S. Secretary of Defense
  • Board Member, Global Markets Board, U.S. National Intelligence Council

  • U.S. Chair, U.S.-China High Technology and Strategic Trade Working Group
  • U.S. Chair, U.S.-India High Technology Cooperation Group
  • U.S. Chair, U.S.-Israel High Technology Forum

With his senior government, enforcement and international experience, he is particularly well-positioned to help clients through crises that involve national security-related regulatory enforcement actions or government investigations by the Office of Foreign Assets Control (OFAC), the Directorate of Defense Trade Controls (DDTC), the Bureau of Industry and Security (BIS), the Financial Crimes Enforcement Network (FinCEN), the Department of Justice (DOJ) and/or the Securities and Exchange Commission (SEC).

Mario has authored many articles and regularly contributes to leading U.S. and international media outlets on the subjects of U.S. national security, international affairs and global business. He is the author of the recently released, A Dealmaker’s Guide to CFIUS, which aims to help buyers, sellers, and other interested parties think through CFIUS within the M&A process.

Prior to his presidential service, he was in private law practice and served as a forward deployed military officer during combat operations.
