The L-1B visa is for employees with specialized knowledge of a company's products, services, research, equipment, techniques, or management procedures. Unlike L-1A, the L-1B is capped at 5 years total and does not offer a direct path to EB-1C. USCIS has heightened scrutiny of L-1B specialized knowledge claims, making it essential to clearly document how the employee's knowledge is truly specialized and not readily available in the US labor market. The specialized knowledge must go beyond general skills—it should relate to the specific company's proprietary processes, products, or systems.
