No. The fee and the gift are per person. A spouse and each unmarried child under twenty-one who joins the application each add a further US$15,000 fee and a further US$1 million gift, and a child of twenty-one or older is outside the accompanying-family category entirely.
Count the people first, then multiply
The per-person structure is the single most consequential fact for a family, and it is easily missed when the programme is described by its headline figure. Anselm's household illustrates every variation. He himself would pay the fee and make the gift.
His wife, as an accompanying spouse, would add both again. His nineteen-year-old son is currently within the unmarried-and-under-twenty-one description, but that description is tested when it counts rather than when the idea is first raised, so a birthday during the process changes his position. His twenty-three-year-old daughter cannot be included on this basis at all and would need to qualify for something in her own right, which is a separate exercise with its own timetable and cost.
Where an employer sponsors an employee corporately, the same per-person pattern applies to the accompanying family rather than a single corporate figure covering everyone.
