That is my point. The comment saying immigrants are 98% of the population of the US is not useful because they are people whose ancestors have been their for many generations. Defining anyone who has immigrant ancestry as an immigrant is pointless. Sometimes it is useful to talk about, say, second generation immigrants, but not endlessly. For one thing, after a generation or two the culture of people descended from immigrants diverges from that of their ancestors, even if their ancestry is limited to just one culture.
