What do you focus on?

Export Compliance

Alexandra López-Casero specializes in U.S. export control and sanctions laws. She advises U.S., multinational, and non-U.S. companies on all aspects of U.S. export controls and sanctions compliance. Her practice spans counseling companies on regulatory compliance, addressing complex, hot-button regulatory questions, drafting and implementing custom-made compliance plans and procedures, and managing voluntary disclosures and internal investigations. A significant portion of her practice also involves performing export controls due diligence on U.S. target companies, advising U.S. and non-U.S. acquirers and strategic investors of compliance risks and potential violations, and post-closing integration/corrective action plans, covering all phases of export compliance, from the first point of regulatory risk through post-shipment activities.

Ms. Lopez-Casero is equally specialized in all three export controls and sanctions regimes: the International Traffic in Arms Regulations (ITAR) involving defense articles and defense services, the Export Administration Regulations (EAR) involving “dual use” and commercial products, and compliance with the embargo and sanctions programs of the Office of Foreign Assets Control (OFAC), as detailed below.

Ms. Lopez-Casero's ITAR experience spans all aspects of ITAR compliance, including commodity jurisdiction and classification, registration requirements, licensing strategies, license proviso compliance, TAAs and MLAs, re-exports and transfers, deemed (re-)export controls and other technology controls, internal assessments and gap analysis, self-audits, disclosures, training and process creation. She represents clients ranging from defense contractors to manufacturers of industrial products, electronic products and software developers on compliance with ITAR. Ms. Lopez-Casero's experience enables her to carefully tailor ITAR compliance strategies to fit each client’s industry and compliance risk. She also works closely with firms that are new to the ITAR and the processes required to conduct an ITAR-compliant business.

Ms. Lopez-Casero also has extensive experience with exports of dual use and commercial products. She counsels U.S., multinationals and non-U.S. companies on the EAR navigating them through all aspects of EAR compliance, including product classification, licensing requirements and strategies, license preparation, end use and end user controls, deemed export controls, technology controls, compliance manuals and processes, and regulatory interpretation. Ms. Lopez-Casero's experience includes software classification and mastering the EAR’s encryption controls and license exceptions.

Ms. Lopez-Casero's OFAC experience covers all U.S. sanctions regimes, including the rapidly changing economic sanctions restrictions regarding Russia, Iran, Venezuela, North Korea, Cuba, and Sudan. Ms. Lopez-Casero speaks and writes regularly on trade control and compliance issues. She has been repeatedly cited by The Wall Street Journal on matters pertaining to export controls and U.S. sanctions, as well as by other publications, including The Export Practitioner and International Trade Law 360.

National Security Reviews of Foreign Investment (CFIUS)

Alexandra has significant experience representing U.S. and non–U.S. companies on all aspects of the U.S. national security review process before CFIUS. Her clients range from technology companies, international construction and energy companies, defense contractors, manufacturers and private equity firms to non–U.S. government-owned businesses. By way of example, some of Alexandra's representative experience in securing CFIUS approval includes:

  • Represented a leading science and technology company based in Baden-Württemberg, Germany, in the merger of its wholly-owned subsidiary with a publicly traded, NASDAQ-listed company, based in Silicon Valley that specializes in advanced materials innovation, with a particular focus on the semiconductor industry.
