It may require assessment of duties, history and applicable procedural steps. Ask what the scope includes rather than assuming the existing file needs only a new title. Price the work by the stages that have to be done, not by the title change. Establishing the qualifying relationship from corporate records, defining the position, documenting the year abroad and assembling the handover evidence are separate pieces of work, and a file missing any one of them costs more later than it would have cost in sequence. Ask which of those stages the estimate assumes is already complete.
Price the actual change being assessed
Separate professional review and evidence preparation from current official charges. A more senior title or higher salary does not replace a qualifying managerial or executive role. The estimate should reflect the facts requiring review.
Split the budget between what the company bears and what the individual bears, because the two are decided by different people on different cycles. Government charges attach to the petition the employer files; confirm current amounts from the official source rather than carrying forward a figure from an earlier filing. Compensation is a separate matter: a raise may be evidence of a more senior role, but salary does not establish managerial or executive capacity and cannot substitute for the organisational evidence.
Where the company has not yet approved the backfill headcount, note that the immigration file cannot be completed until it does.
