The official FAQ currently says that after the application and processing fee are received, the process should take weeks, while also making the outcome depend on timely submissions, vetting, eligibility and visa availability. Treat that as general official guidance rather than a guaranteed result or move date, and recheck the page before relying on it.
Anchor every date to a milestone actually reached
The official FAQ currently says the process should take weeks after receipt of the application and processing fee, assuming timely submission of additional documents and fees. That statement is general guidance, not a guaranteed household date: vetting, the gift instruction, eligibility for EB-1 or EB-2, visa availability and immigrant processing still affect the outcome. The household should therefore avoid selling a home in Sainte-Catherine-de-la-Jacques-Cartier or ending employment on the strength of an expected date.
Attach each personal commitment to a milestone actually reached, and if a U.S. employer is involved through the corporate track, ask what happens if processing runs longer. Recheck the official page at every stage.
