This may be hard to believe. But the parents made a bank account under the son's name, and there is a substantial sum of money in it.
So yes, he can pay for himself for the next 2 years.
And, what would happen to all the money his parents made here, and their store? Would the governement seize it?
Because if the government does Seize it, then its the same whether or not he's supporting himself or if his parents are suporting him.
Because if the government does seize it, then the parents will have no source of income either.
But say that the son has no money, even then, he can't be placed under care of foster family so they could support him for the time being. He's gonna be 17 in april, so it won't even be 2 years, more like 1 year 4 months.
