National Security

The legal and regulatory frameworks governing national security in the United States have expanded significantly in recent years, as have the government's enforcement priorities. Miller & Chevalier assists individuals and companies, whether in the U.S. or abroad, in navigating the complexities of even the most challenging national security legal matter. 

Our practice focuses on advising U.S. and non-U.S. companies regarding the Committee on Foreign Investment in the United States (CFIUS) process, as well as other forms of foreign direct investment. We also advise clients on registration and enforcement matters relating to the Foreign Agents Registration Act (FARA). Additionally, the firm concentrates on compliance, investigations, and litigation relating to cybersecurity, classified information, and the Foreign Intelligence Surveillance Act (FISA).
