Our Services
We provide sophisticated legal counsel on the full range of national security matters affecting businesses, financial institutions, and foreign governments operating in or with the United States. Our practice encompasses Committee on Foreign Investment in the United States (CFIUS) reviews, export controls, sanctions compliance, and matters arising under the African Continental Free Trade Area (AfCFTA) framework. With deep roots in Washington, DC — the nexus of national security policy and regulation — we guide clients through the complex intersection of global commerce, geopolitical risk, and U.S. national security law. We help clients anticipate regulatory scrutiny, structure transactions to mitigate risk, and respond decisively when national security concerns arise.
We provide sophisticated immigration counsel to businesses, entrepreneurs, foreign governments, and individuals navigating the complexities of U.S. immigration law. Our practice encompasses corporate and business immigration, including nonimmigrant and immigrant visa petitions, employment authorization, and I-9 compliance, as well as EB-5 investor visas, extraordinary ability petitions, and executive and intracompany transferee visas. We understand that immigration matters are not just legal challenges — they are business-critical decisions that affect your people, your operations, and your growth. Our Washington, DC-based team delivers precise, strategic counsel that keeps your workforce and your business moving forward.
We provide sophisticated legal counsel to businesses of all sizes competing in the federal marketplace. Our government contracting practice covers the full lifecycle of federal procurement — from bid preparation, proposal strategy, and contract negotiation to performance disputes, audits, and contract closeout. We advise small businesses, emerging contractors, and established government contractors on Small Business Administration (SBA) program eligibility, including 8(a), HUBZone, and Service-Disabled Veteran-Owned Small Business (SDVOSB) certifications, as well as Federal Acquisition Regulation (FAR) compliance, teaming arrangements, subcontracting agreements, and bid protests before the Government Accountability Office (GAO) and the U.S. Court of Federal Claims. Based in Washington, DC — the center of federal procurement — we give our clients the strategic advantage they need to win and successfully perform government contracts.
We provide sophisticated counsel across the full spectrum of securities law and financial services regulation. From SEC compliance and securities offerings to investment adviser registration and regulatory enforcement defense, our attorneys bring deep Washington, DC expertise to the complex legal challenges facing public and private companies, investment funds, broker-dealers, and financial institutions. We help our clients navigate an ever-evolving regulatory landscape with precision, discretion, and strategic insight.
