IN THIS GUIDE · Distinguish access permission from the knowledge needed to use internal information
Start with the L-1B eligibility and application overview
Explain what the applicant understands beyond access
Describe the relevant organizational process and a representative use of the employee’s knowledge. Identify special knowledge of the organization’s interests and international application, or advanced knowledge of its processes and procedures. Do not equate a security clearance, password or job grade with either basis. For a historical-pigment analysis laboratory, record the specific internal method, training, and assignment use before relying on access labels. This distinguishes specialized organizational knowledge from a permission that another employee could receive.
Describe the access available for the proposed work
Identify which tools or records the U.S. role will actually use and whether authorization is current or planned. If access is restricted during the transfer, explain the operational arrangement rather than portraying unavailable materials as already accessible. The immigration account should not suggest bypassing the employer’s controls. For a historical-pigment analysis laboratory, record the specific internal method, training, and assignment use before relying on access labels. This distinguishes specialized organizational knowledge from a permission that another employee could receive.
Document employment and the qualifying organizations
Generally support a continuous year of qualifying full-time foreign employment within the relevant preceding three years, a qualifying corporate relationship and continuing qualifying operations in the United States and abroad. Access logs may corroborate an activity, but do not alone prove its location, the whole employment period or the substance of specialized knowledge. For a historical-pigment analysis laboratory, record the specific internal method, training, and assignment use before relying on access labels. This distinguishes specialized organizational knowledge from a permission that another employee could receive.
Explain knowledge rather than ownership value
Knowledge that exists only in one person's head is hard to prove; knowledge documented in internal manuals, training records, project close-out reports and certifications is easier. The knowledge need not be proprietary, unique or held by only a few employees, and the case is assessed on the totality of the evidence. Explain what the applicant knows, how that knowledge was acquired, why it matters to the proposed work and what a normally skilled worker would not know. For an offsite placement, the contract, statement of work, reporting relationship, and supervision record help test whether the assignment is controlled by the petitioner rather than labour-for-hire. The first review should yield names of controlled documents, training modules, and people who can verify the employee's role. If a customer owns the work product, distinguish that fact from the petitioner’s own specialized methods.
