No. Job creation is assessed through the case as a whole and against the legal deadlines that apply at each stage, not only at the I-829. Material changes to the plan or the model can matter while your petition is pending, so raise them with counsel when they occur.
Where the revision sits in the sequence
The stages are petition, visa availability, then an immigrant visa abroad or an adjustment you are genuinely eligible to file, conditional residence, and later the I-829, which is ordinarily filed during the ninety-day period immediately before the second anniversary of conditional residence. They are not always strictly sequential — a concurrent adjustment can exist where eligibility and a visa number allow. The business plan's projections must support the applicable legal job-creation requirements; a revised commercial schedule does not automatically extend those requirements.
Several years in total: petition adjudication, then a wait for visa availability if the investor's chargeability is backlogged, then residence processing, then two years of conditional status and the removal-of-conditions petition. Anchor the removal calendar to the date conditional permanent residence began, not to investment meetings, petition approval, or a fiscal year. Sale timing, petition processing and Visa Bulletin availability together set the earliest realistic move date.
