In the city I grew up in, official notices were routinely made in English, Spanish, and Vietnamese, and I regularly encountered people speaking Korean and Chinese as well. Even my grandma's rural town, with a population of under 5,000 and an hour's drive to the closest city, has people and restaurants representing four or five different nationalities. If you're perceiving the US as a country where everyone only speaks English and only eats at McDonalds, that's not accurate.
Aha, things have improved since last century. When in California I did use spanish as well as english, and in Louisiana french as well as english — but back then the concept of "melting pot" was still current, so one of these languages was clearly the prestige dialect.
Looking at the current cabinet, I'm sure if I scrolled enough in @SecElaineChao I could find some chinese. Sorry for my outdated impression.
but we utterly lack any mother-tongue sinophones. And although our current president, @s_sommaruga, has some romanche in her feed, she uses much more english.)
