Review whether the sequence changes the actual duties, supervision or knowledge claim.
Update the assignment before relying on it
Provide the amended plan and actual worksite arrangement. A rearranged schedule may be minor or substantive depending on its facts; do not assume the original description covers every change.
File once the year abroad is confirmed and the process description is complete, allow for standard processing or use premium processing, and set the assignment start after the expected approval, not before. If the project changes materially during preparation or after approval, assess the immigration effect rather than assuming any internal assignment is covered. Freeze and date the version used for petition preparation, then create a comparison listing changed duties, locations, supervision, and customer sites. Start with the assignment’s real launch date and work backward through evidence collection, internal technical review, petition preparation, and travel planning. The transfer can be deferred until the applicant has worked with the receiving method; the assignment can be rewritten around the knowledge actually held today; or a different category may fit better and should be assessed on its own conditions. If the employer needs the person on site by a fixed date, the blocking question is remaining time; if the duties have changed since the last approval, it is whether the new work still rests on specialized knowledge. A short product launch calendar may support a limited assignment, but it does not replace the foreign-employment or specialised-knowledge requirements.
