Only the preparation. Adjudication times and the monthly bulletin's cut-off dates for their chargeability are outside anyone's control, which is why preparation should start immediately.
Control the part you can control
Three timelines run at once. The family controls the first, which covers the financial history, project diligence and the commitment of capital, and starting it immediately is the only lever available. The second is adjudication, which varies and cannot be predicted from someone else's experience. The third is visa availability, published monthly as cut-off dates by country of chargeability, which can add or remove years regardless of how well the file was assembled. Because conditional residence runs for two years and is followed by a further petition, the whole arc extends well past the first approval. Plans that depend on a particular arrival month should be treated as provisional throughout.
Use three calendars: petition preparation, immigrant-visa availability, and the project’s job-development schedule. Official visa information settles availability; executed project milestones settle what the enterprise must do; filing receipts settle case events. The decision is whether the household’s desired move date survives if those clocks diverge. Conditional residence begins only after the applicable immigration process reaches that stage, and the investment and job evidence must continue afterward. Hypothetical example: a modular-housing supplier sees that construction hiring begins long before a visa number may be available, so the investor assesses the sustainment risk before subscribing.
