No automatic citizenship result is described for participating relatives. Their immigration position needs to be understood under the actual programme and their circumstances.
Keep future goals separate
The FAQ addresses a spouse and unmarried children under 21 for initial inclusion and additional charges. Ask counsel what status each would obtain and what is needed before working or relocating. Do not use a household citizenship promise as a substitute for a person-by-person explanation of the immediate application.
Set the limits of the family claim explicitly. The FAQ addresses a spouse and unmarried children under 21 for initial inclusion, with additional charges; that is a statement about who may be included and what is charged, not a statement that each relative will obtain a particular status, at a particular time, or that anyone acquires citizenship. Hypothetical example: a veterinary clinic group principal is told the household is covered, and nobody has asked what happens to a child who reaches 21 during the process or to a relative outside the described categories.
Ask counsel to work person by person: which status each would seek, what each may do on arrival, whether employment authorisation follows, and which relatives fall outside the programme altogether. Relatives outside those described categories need their own route identified separately, and that answer belongs in the plan before anyone commits to relocating.
