Review the actual duties and knowledge they require. Do not retain an advanced-knowledge description unsupported by the assignment.
Match capability to proposed work
An employee may be highly experienced while the particular role uses different skills. Explain the real US need rather than overstating it.
Have the applicant and role assessed under the requirements of the route actually proposed, including the blanket specialized-knowledge professional condition. Only once that is settled does the evidence-gathering begin: protocols, training records, validation files and an assignment description. At the same time, build the specialized-knowledge record from internal assignments, training, problem-solving responsibility, and the particular company processes involved. L-1B requires qualifying specialized-knowledge work, a parent, branch, subsidiary, or affiliate, and one continuous year of full-time work physically abroad within the relevant preceding three-year period. Preserve the material change and assess any effect on the proposed transfer rather than promising a fixed immigration outcome. A delayed project may affect the planned duties or other relevant facts, even if the company still wants the same employee. Do not assume that urgency makes a particular next step appropriate or that changing the proposed start date resolves the prior issue. For timing, compare the requested assignment with the five-year aggregate L-1B limit and record changes in duties as they happen.
