> Wikipedia says there's a recent rate of about 1 million immigrants per year, about half of which are changing status for people already here. Would that mean they weren't counted as immigrants when they first arrived, because they had the wrong 'status'? Or are they counted twice, first when they arrive, and again when they change status? Edit: It occurred to me, immigration to the US is probably concentrated in the south, so the "15% of total US population being immigrant" is not the most relevant statistic to compare to.
