An L-1 Expert Opinion Letter provides independent expert analysis supporting a petition for an intracompany transferee. L-1A covers managers and executives being transferred to a U.S. office; L-1B covers employees with "specialized knowledge" of the company's products, services, research, systems, or management. Expert letters are critical when USCIS questions whether the role truly qualifies as managerial/executive or whether the employee's knowledge is truly "specialized."
USCIS frequently issues RFEs on L-1 petitions challenging the managerial nature of the role (is the beneficiary truly managing professionals, or performing day-to-day operational tasks?), the specialized nature of the knowledge (is it truly unique to the company, or is it general industry knowledge?), and the qualifying relationship between the U.S. and foreign entities.
Our expert opinion letters provide objective, third-party validation that the beneficiary's role, knowledge, and organizational context meet USCIS requirements — using industry analysis, organizational structure assessment, and knowledge complexity evaluation to build a compelling case.
Our expert opinion letters are structured to address the specific evidentiary requirements USCIS applies to L-1 petitions.
The beneficiary must be transferring to the U.S. in a managerial or executive capacity. USCIS evaluates whether the person manages professional employees (not just first-line supervisors), controls a department or function, has authority over day-to-day operations, and exercises significant discretion without close oversight.
The beneficiary must possess "specialized knowledge" — defined as special knowledge of the company's product, service, research, equipment, techniques, or management, or advanced knowledge of the organization's processes and procedures. This knowledge must be distinct from general industry expertise.
The U.S. and foreign entities must have a qualifying relationship — parent, branch, subsidiary, or affiliate. The beneficiary must have worked for the foreign entity in a qualifying capacity for at least 1 continuous year within the 3 years preceding the transfer.
