No. Only the investor’s spouse and unmarried children under 21 qualify as derivatives, and each person’s facts should be verified.
Identify people by legal category
A multigenerational household planning to relocate should be analysed from the actual proposal, not from an abbreviated label in an email or a planning spreadsheet. The principal investor’s petition and conditional residence process have defined derivative rules; relatives outside those categories need an independent immigration basis. Start with the facts that exist today: names of parties, dates, duties, ownership rights, payments, and any condition that could change the arrangement.
A future intention can be useful context, but it should not be presented as an accomplished fact. Keep marriage, divorce, birth, adoption, identity, and any name-change records organized alongside a date-sensitive family chart. Keep originals available and make translations complete where the chosen process calls for them.
If a document is unavailable, explain the gap accurately rather than filling it with an assumption. A parent who funded the capital, an adult child, or another relative may need separate planning even if everyone expects to travel together. That person’s nationality, status record, age, planned study, and planned activity may require a separate review.
Government fees, filing locations, visa availability, and procedural instructions can change, so confirm them from the current official source before money is committed or travel is booked. Confirm the current definitions and visa-processing instructions before making commitments based on an assumed household outcome. The purpose of preparation is a clear factual record and an informed route comparison; it is not a promise that an officer will reach a particular result.
