No. Track the applicable immigration deadlines independently and assess the project delay’s effect on the evidence required for the case.
Explain the change rather than assuming an extension
Document the outstanding step and the resulting changes to operations or hiring. An updated opening date does not itself extend the I-829 period, and a timely opening does not guarantee removal of conditions.
For an applicant pursuing immigrant processing abroad, petition approval is followed by the applicable visa process, subject to visa availability and individual requirements. Keep evidence of that residence date for the principal and derivatives, then prepare the removal filing for the 90-day period immediately preceding the second anniversary. Conditional residence means that post-admission proof matters: preserve the documents that demonstrate the capital remained as required and that jobs were created or are being created under the applicable structure. The schedule has several stages: investment and petition evidence, immigrant-visa or adjustment processing when available, conditional residence, and the later request to remove conditions. Visa availability by country of chargeability affects when the family can immigrate, so check the Visa Bulletin rather than assuming Canada is current. The later condition-removal filing is an evidence-heavy stage that depends on what happened after admission.
