I think you may have misunderstood what those numbers represent. They aren't saying that there are more foreign-born STEM workers than US-born STEM workers. They are saying that among all the foreign-born workers in the US, 26% of those workers are working in STEM. Among all the US-born workers, 24% are working in STEM. There are around 29 million foreign-born workers in the US, and around 131 million US-born workers (if Google has given me correct numbers). In percentages 18.1% of workers in the US are foreign-born and 81.9% are US-born. With 26% of the foreign-born workers in STEM and 24% of the US-born workers in STEM that would be about 7.5 million foreign-born STEM workers in the US and 31 million US-born STEM workers in the US. Among STEM workers in the US then it would 19.5% are foreign-born and 80.5% are US-born.
