Let us talk about a case where two Canadian parents who were born in Canada adopt a Chinese girl. Once the adoption is finalized, the parents have to choose between direct citizenship and naturalization. Naturalization strikes me as being more complicated. Moreover, that is why direct citizenship is offered as an option. But it is as though we offered parents a way to facilitate adoption, but penalized them from a bureaucratic standpoint by making this situation comparable to the situation of a child born abroad.
What would we lose as a state if we allowed the children of people who opted for direct citizenship to pass on their citizenship by descent, as in the case of naturalized children?
