The cited data refers to foreigners, not immigrants. Although I would argue that the distinction in this case is largely nitpicking anyway, since as far as I understand foreigners in this context are prospecting immigrants, who are already in the country and await the processing of their application for citizenship, or non-citizens simply living here for any reason.

I’m not even sure what you are trying to argue, you even agree with me that the data shows a very concerning trend over the years. Just semantics?
