In your classes at school, did you have children of any of the following racial groups?

We had some students from all of those groups, but they were in a tiny minority. My high school was close to an Air Force base, so we had many students from varied NATO countries. Most students' parents came from other countries or other states. The townies were about as scarce as the non-White students.

Racial groups at my school were mostly :

European of German, Ukrainian, British descent
MENA mostly Levantine Arabs, some Kurds and Persians, and Iraqis of various origins
East Asian primarily Chinese and Korean
South Asian primarily Sikh Punjabis

Sadly there was no Assyrian, Mandean, or Mizrahi Jews, I just interacted with the following online never in person.

I had an Afro-Turk classmate in high school, she was entirely Black with Turkish identity.

Nobody was considering her foreigner/outsider though, her dialect and culture was pure Aegean.

All of them. My elementary school classes had maybe 3 or 4 white kids (including me) out of 20 - 25 every year.
