Update it when material duties, knowledge or work arrangements change, and have the revised proposal assessed before relying on earlier conclusions.
Keep clarity faithful to current facts
Identify what changed and which supporting records now apply. A concise old explanation can still be inaccurate for a new assignment. Do not preserve attractive wording after it stops describing the actual work.
Review the employee’s actual knowledge of the version used in the proposed US work. Premium processing shortens USCIS adjudication to its current official period, but a request for evidence can suspend that clock without a predictable one-month addition. Update the itinerary, statements of work, reporting lines, access arrangements, and lesson plan before the new location begins. If missing experience is essential, completing genuine work abroad before filing may change the evidence; it should not be described as finished. Confirm the qualifying year and relationship first, assemble the specialized-knowledge record next, and reserve travel commitments until the filing strategy is settled. Fixing the reporting line and the offsite arrangements in writing at the same time avoids rebuilding them under a deadline. If the affiliate's contract is still being negotiated, wait for signed terms rather than filing on a draft; a change in the control language after filing can undermine the case.
