What occurs to me about this chart of the Immigrant Share Of US Employment is that although there's a slight dip at the right end, it's heading for twenty percent, compared with 15 percent at the beginning of the Obama Administration.

We are literally going to have to get a bigger chart.

However, that can change if Biden is defeated—see the dip during the Trump Administration. Immigrations levels are set by government policy, including the "policy" of refusing to enforce the law.
