Potentially, if the actual knowledge and proposed duties meet the applicable requirements. Joint development alone does not answer the eligibility question.
Explain the employee’s own knowledge
Identify what the applicant learned and applied, its organizational relevance and its U.S. use. Do not treat the entire collaboration’s technical achievements as proof that every participant possesses the same knowledge.
Industry experience alone is insufficient; L-1B focuses on specialized knowledge connected to the qualifying organization and its use in the U.S. role. Identify the company-specific product, process, procedures, international application, and refinements the worker understands; then show why that command is special or advanced compared with knowledge ordinarily found in the organization or field. Spending can corroborate how knowledge was acquired, but L-1B eligibility depends on special product knowledge or advanced process knowledge, a qualifying related organization, and one continuous foreign year during the relevant preceding three years. The employee must hold special knowledge of the petitioning organisation's own product, service, research, equipment, techniques, management or other interests and their application in international markets, or an advanced level of knowledge of its processes and procedures. Start with the actual process: versions of internal manuals, training modules, controlled procedures, project histories, and access records can explain why the knowledge is special or advanced.
