A change in duties, client placement, or the employing arrangement can affect the basis of the proposed case. Provide the revised documents for a fresh review rather than assuming the original plan or approval automatically covers the new activity.
Keep the assignment history and status calendar aligned
Record what was originally proposed and the date anything changed. Identify which facts need fresh review and whether further steps are needed before the new work begins. Keep the actual approval and status dates visible throughout, and do not treat a client delivery deadline as permission to begin work whose immigration basis has not actually been resolved.
Freeze a dated copy of the approved or proposed assignment, then compare every revision in duties, worksite, supervisor, client contract, and entity. When an L-1B worker is stationed primarily at an unaffiliated worksite, the unaffiliated employer cannot principally control and supervise the worker, and the placement cannot be essentially an arrangement to provide labour for hire rather than to use the petitioner’s specialized knowledge. Confirm whether new facts require an additional filing or other action before activities change; never let a commercial deadline answer that legal question. Track time already used because the general L-1B maximum is five years, subject to regulatory exceptions and recapture rules. A common mistake is treating the same client name as proof that a materially different placement remains covered.
Hypothetical example: a Windsor agricultural-drone company receives approval to deploy a specialist under its project lead, but the customer later asks him to join its surveying team and report to its supervisor. The company records the requested change, pauses those activities, and supplies the new statement of work and supervision chart for review. It recalculates his status history before rescheduling travel instead of assuming the original approval follows any assignment involving the same mapping platform.
