IN THIS GUIDE · Review the specialist’s duties when training moves to a later phase
Identify the assignment during the delay
Hypothetical example: an employee was to teach an advanced internal process, but the launch now begins with general support tasks. Describe both stages accurately. Do not use a future training description to conceal materially different initial duties. Break the gap-period assignment into tasks and connect each task to the claimed special or advanced knowledge. A generic support assignment may be commercially sensible, but its description should not be disguised as training or product deployment. A clear sequence can show which duties begin immediately, which require system access, and which depend on a later launch.
Explain the actual qualifying knowledge
Assess special knowledge of the organization’s products, services or related interests and international application, or advanced knowledge of its processes and procedures. The knowledge need not universally be unique or secret, but general occupational skill alone is insufficient. Identify the applicant’s genuine acquisition and application rather than relying only on a training title. Use technical materials selectively and explain them in plain operational terms. Training records, internal manuals, product diagrams, version histories, and manager declarations should show both the distinctive knowledge and how the employee will apply it. The relevant question is not whether the materials look sophisticated; it is whether they substantiate the actual role.
Confirm organizations and placement
Provide the qualifying relationship and required foreign employment history. Explain actual supervision and customer sites. Principal placement at an unaffiliated employer’s worksite requires assessment of control and supervision and whether it is labour for hire rather than a qualifying product-or-service placement requiring specialized knowledge. At a customer site, document who sets priorities, reviews output, supplies tools, and controls the employee’s work. The contract, statement of work, and project plan should tell the same story. If the arrangement changed from product implementation to supplying general labour, that distinction should be addressed directly rather than left for an officer to infer.
Reassess material changes before relying on authorization
Identify the current scope and documents that no longer describe it. A customer’s new request or postponed phase does not itself expand permission. Review the actual intended activities rather than assuming the earlier proposal covers every interim role. Use a change table that pairs each former duty with the current duty, proof of knowledge used, work location, supervisor, and client impact. This makes it easier to identify a material change before the employee begins it. It also reduces the risk that a later explanation relies on an outdated training narrative.
Complete the foreign-employment and new-office assessment
L-1B generally requires one continuous qualifying year of foreign employment within the relevant preceding three-year period, along with qualifying organizations that meet the doing-business requirements. Assess actual dates and locations; U.S. days do not count toward the foreign year. For a U.S. organization doing business for less than one year, the L-1B new-office evidence includes sufficient premises and financial ability to pay the employee and begin doing business. Initial new-office approval is limited to at most one year. The required parent, branch, subsidiary or affiliate relationship must link active U.S. and foreign entities. L-1B status is capped at five years. Reconcile foreign employment dates with payroll and travel evidence, then verify the U.S. entity’s actual operations. For a new office, financial capacity and premises must support the proposed start of business; an aspirational market presentation cannot replace current operational proof. Build the evidence around what the organization can show now.
