Only when the timing of the sale, the investment and the move have been planned together. The proceeds must be committed before the petition is filed, but the family may wait years for residence, so selling the home to fund the investment usually means renting in Québec, not moving to the United States.
Funding the investment and moving are separated by years
EB-5 has a long sequence: the capital must be committed to the enterprise or escrow before the immigrant petition is filed; adjudication follows; a visa number must be available under the Visa Bulletin for the investor's chargeability; then the family completes consular processing or adjustment of status; then two years of conditional residence run before the removal petition, during which status continues while it is decided. Hypothetical example: a Sainte-Brigitte-de-Laval household sells its house to fund the investment, assuming they will move within months, and instead spends two years renting locally while the petition and visa process run.
Sequence the sale so that proceeds arrive when the subscription requires them, keep the family's Québec employment and schooling in place until a visa is actually issued, and ask the project sponsor what happens if the ten jobs are not complete when the removal petition falls due, since the family's residence depends on it. A filing receipt authorizes nothing and should not be treated as a reason to give notice.
