Base commitments on verified progress and advice about the actual application, not a general statement about fast processing. Additional submissions, review and visa availability can affect the outcome and timing.
Set a decision trigger for each moving expense
For housing, school deposits and employment changes, write down which confirmed event the household wants to see before committing. Identify refundable options where commercially available without assuming they solve immigration uncertainty. Keep government notices accessible to the adviser and report material changes in family circumstances. The resulting plan is a way to manage decisions during uncertainty; it is not a promised completion schedule.
The parts of the process that cost nothing but time, meaning the admissibility review, the family eligibility check, the cross-border tax opinion and a careful reading of the official program page, can begin before the business sale closes. Official material describes the process in terms of weeks, but that is a description rather than a guarantee, and the final step depends on visa availability under EB-1 or EB-2 as well as vetting, interview scheduling, and any request for further documents. A practical sequence is to preserve the official instructions, gather identity and admissibility records, complete the requested filing, await the required notice, and make no irreversible business or travel decision based only on an expectation of approval.
