L-1B is the intracompany route for an employee whose specialized knowledge of the company's product, service, research, equipment, techniques or management, or advanced knowledge of its processes and procedures, is needed at a related U.S. entity. Configuration and change histories, authorship records for internal procedures, training materials and completion records, an organizational chart, and a signed statement quantifying how many staff hold comparable knowledge. The petition should explain why the claimed knowledge is particular to the company rather than merely a general engineering skill; there is no separate requirement to prove that workers are unavailable in the US labour market. The applicant must have been employed continuously for one year within the three preceding years by a qualifying entity abroad, in a managerial, executive or specialized knowledge capacity, and the United States role relied on specialized knowledge as defined.
