L-1B concerns the specialized-knowledge role and its applicable requirements. Do not substitute the L-1A managerial or executive role test for the actual L-1B analysis.
Use the right new-office evidence
Assess the knowledge, employment and company requirements together with premises and financial ability to pay the employee and commence business. A template written for a manager may not explain those facts adequately.
The regulation defines specialized knowledge as special knowledge of the petitioning organization's product, service, research, equipment, techniques, management or other interests and its application in international markets, or an advanced level of knowledge or expertise in the organization's processes and procedures. What counts is knowledge that is genuinely proprietary or advanced within the organization: an internal formulation, a method developed in-house, an unpublished protocol, a system the company built for itself. The test asks whether the knowledge concerns the petitioner's own product, process or procedure, or is advanced knowledge of how that organisation does things, rather than expertise available generally in the field. Customer familiarity may support the knowledge narrative, but it cannot become payroll service retroactively or turn general industry skill into company-specific knowledge. General trail-building skill, however advanced, is not specialized knowledge; the firm's documented build specification and the builder's advanced command of it can be.
