Iranians aren't "brown people." They're caucasians.

Only in the US, at present. In the racist US immigration policy of a century ago, Arabs were a distinct, and unwanted, race.

from the net sifter:

In the 1920s, US immigration policy ambiguously defined Arabs—primarily immigrants from "Greater Syria" (modern Lebanon, Syria, Palestine, Jordan)—as "Asiatics" or "Turkey in Asia," often classifying them as non-white. While initially considered white, legal challenges arose in 1910–1923, as they were sometimes classified as "yellow" and denied naturalization.

Regional Origin: Most immigrants were Arabic-speaking Christians from Ottoman-ruled Syria and Lebanon.

Legal Classification: By the early 1910s, federal authorities and courts increasingly classified Arabs as "Asiatics" or "other" to restrict citizenship under statutes limiting it to "free white persons".

Restriction: The 1924 Immigration Act (Johnson-Reed Act) significantly restricted immigration from the region..

Yes, technically, Persians are not "Arabs" either. But, since Trump the Most Perfect is turning the clock back a century, embracing the racist memes of the time that only northern Europeans are "white" would be the correct read.
