IN THIS GUIDE · Explain what the employee would do in each phase of a rollout
Start with the L-1B eligibility and application overview
Describe the work at each milestone
Hypothetical example: an employee configures an internal platform, supports testing and later handles service requests. Identify the responsibilities in each phase and the knowledge they use. Do not rely on the initial configuration work to explain an indefinite later assignment with materially different duties.
Identify the established knowledge
Explain special knowledge of the organization’s product and its international application or advanced knowledge of its processes and procedures. Use relevant records of the applicant’s experience. The standard does not universally require unique or proprietary knowledge, but a project title alone does not explain the knowledge claimed.
Make supervision and locations clear
Identify who directs the work in each phase and where it would occur. If an unaffiliated client site is involved, the arrangement needs assessment under the specific L-1B restrictions, including control and the nature of the placement. Neither a client-site label nor a company assurance supplies the complete answer.
Plan how changes will be reported
Keep the proposed phases and expected duration distinct from confirmed work. Explain how changes in duties, supervision or location will be brought back for review. Assess the qualifying entities and foreign-employment period separately; a rollout schedule cannot replace those requirements or authorize work.
Put a start and an end date on every phase
Phases without dates cannot be assessed, because the question is not only what the employee would do but for how long and in what order. Write each phase with a start, an expected end and the duties belonging to it, and mark which of those dates are contractual and which are estimates. L-1B rests on one continuous year of qualifying employment with a related entity abroad within the preceding three years, and on specialized knowledge of the organisation's product or its procedures; the length or prominence of the project establishes neither. L-1B stay is also generally capped at five years, so a rollout expected to run for several of them should be planned against that limit rather than into it. Where a phase is expected to repeat across successive deployments, say so, since a cycle described honestly is easier to assess than a single phase presented as though it were the whole assignment.
Decide now what a change of phase will trigger
Set the review points before the schedule starts moving, because a phase change noticed in retrospect has already happened. Agree with the employer which events prompt a fresh assessment: a shift in who directs the work, a move to a different site, a materially different set of duties, or an extension beyond the period described. Record the date each trigger fires and what was done about it. Hypothetical example: a specialist transferred to configure a dental-laboratory production system is asked, eleven months in, to take over routine servicing for a client of the employer at that client's own premises. Both the duties and the supervision have changed, and the arrangement needs assessment under the L-1B provisions governing placement at an unaffiliated worksite, including control over the work. Treating it as a continuation because the project name is unchanged is precisely the error a trigger list exists to prevent.
