Review the changed activities, location and timing before assuming the original plan covers them. A scheduling change does not create immigration permission.
Confirm what would actually begin
Identify whether the applicant would learn, observe or perform tasks and where. Have the appropriate status and process assessed. Do not rely on a future approval or the employer’s preferred start to authorize present activity.
Review whether the proposed duties and knowledge connection remain accurate. Add premium processing if the crop calendar leaves no room, and plan for a request for evidence rather than assuming a clean approval. The recurring mistake is treating a short deployment window as a reason to begin productive work while a case remains pending. Check the employee’s authorized period and the general five-year maximum rather than assuming a venue change extends anything. Working back from a four-month client onboarding, filing in the first month preserves more time for any response and final decision, with the analyst presenting the approval notice at the port of entry as a Canadian citizen without a visa appointment. A later promotion or changed role may require its own analysis rather than an assumption that the original limit changed.
