Explain that connection precisely rather than presenting every past project as part of the future assignment.
Use the actual scope
A narrower role may need a focused account of relevant knowledge. Do not inflate the US duties to match the résumé or invent responsibility the employer does not propose.
If the business adopts a new method or the employee's proposed U.S. duties change, document the change and have it reviewed rather than relying on the original filing to cover a different set of facts. Freeze a dated copy of the approved or proposed assignment, then compare every revision in duties, worksite, supervisor, client contract, and entity. Build the timeline around the knowledge-dependent tasks, the qualifying employment record, project launch and the chosen immigration step. Keep the employee’s actual status dates visible while the business reschedules, and determine the proper next step if the original assignment no longer exists. If the calendar does not fit, change the assignment dates rather than compressing steps nobody involved controls. Confirm the qualifying organizations, the continuous qualifying foreign year in the preceding three years, and the particular knowledge before relying on a project need. For timing, compare the requested assignment with the five-year aggregate L-1B limit and record changes in duties as they happen. An urgent department deadline does not itself establish specialized knowledge or permission for a different assignment.
