The Company
Fesenko, P.C. Law Offices was among the first American law firms to systematically handle matters arising from US sanctions against Russian nationals and Russian-owned companies. OFAC sanctions removal remains the firm’s principal practice area. We represent clients on all sanctions matters before the Office of Foreign Assets Control of the US Department of the Treasury (OFAC), as well as in dealings with other US government agencies and departments.
Our clients include some of Russia’s largest corporations and their beneficial owners across key sectors of the economy. Our portfolio features a leading Russian energy company, four international metallurgical holdings, seven financial institutions, and several top-tier IT companies. We also represent Russian, European, and Asian entities controlled by ultra-high-net-worth (UHNW) individuals, as well as other clients navigating sanctions-related matters and seeking to restore their international business reputation.
We offer the full range of legal services on US sanctions matters: removal from the OFAC SDN List, asset unblocking through specific OFAC licenses, litigation against OFAC, sanctions compliance advisory, and audit support. Our years of experience and established professional relationships allow us to resolve even the most complex cases, delivering high-quality, efficient work for every client.
