No. I mean people who are African from Africa and Hispanics as colloquially defined. Should Indian engineers get precedence over them?

Ceteris paribus, no. From a utilitarian perspective, engineers are on average more valuable than non-engineers. Doesn’t matter what ethnicity or continent or culture they come from. Biasing that measure with an arbitrary ethno-socio-geographic filter feels like backing into a rationale over thinking from first principles.

So you’re advocating for the US to restrict immigration to only highly-skilled migrants? Would you be ok deporting non-engineer Dreamers?
