No. Family eligibility follows each petition, not the company. Each investor's eligible spouse and unmarried children under 21 are derivatives of that investor alone, assessed individually for admissibility. Age protection is fact-specific and cannot be promised. A shared business does not merge two families into one immigration case.
Why one family may move while the other waits
Timing depends on each case's own facts, including visa availability and the chargeability that usually follows country of birth rather than a Canadian address or passport. In a hypothetical pair, one investor's family reaches an interview while the other's petition is still pending. Any move to the United States must rest on a status the family actually holds; a pending case is not permission to work or relocate.
A child who is twenty when the petition is filed may be older at later stages, and the statutory protections that address that situation are technical and depend on dates and on how the case proceeds. Analyze three issues separately: the principal investor’s policy or management participation, each relative’s derivative eligibility, and which employees count toward job creation. Collect passports, civil records and each person’s case notices; derivatives generally immigrate with or after the principal, not merely when construction reaches a milestone.
