They should consistently describe the real proposal, with material differences explained or corrected.
Check the current agreement
Resolve discrepancies in duties, employer, duration or conditions. Do not submit an old description that no longer reflects what the parties intend. Build the file from records that existed before the immigration explanation: the executed offer or engagement, a detailed duty description, compensation terms, educational records, and any required licence.
Compare names, dates, salary, supervisor, location, and duration across each document. The first review should produce a discrepancy list, not a rewritten story. Hypothetical example: an urban planner’s offer says the work begins in April, while the customer contract says the project ends in March and identifies another employer.
The applicant should obtain an accurate clarification from the responsible parties before using either document. A letter that silently ignores the conflict can create a credibility concern. Where education was earned outside the usual jurisdictions, obtain an evaluation that addresses the credential actually required for the occupation, rather than a broad résumé summary.
Keep ownership documents if the applicant has a business interest, because the employment arrangement must be assessed on its own facts. Sequence the file by proving citizenship and qualifications, then the employer-directed assignment, then temporary duration. Do not rely on a travel booking, recruiter message, or generic job advertisement as a substitute for the employer’s specific evidence.
