Our lawyers and policy advisers are well-known and respected by senior government officials, public international law professionals, and opinion makers worldwide.

We advise countries, multinational corporations, and individuals on some of the most challenging and sensitive matters of international law, foreign affairs, and national security. The variety and depth of our senior leadership enable us to provide service to clients on innovative and complex issues of first impression. Our extensive and high-level government experience makes us especially responsive to the internal, budgetary, and political concerns of foreign governments. We also provide strategic guidance and assistance to senior executives of corporate clients regarding global market entry strategies and managing global political risks.
