According to my friend who comes from Pakistan, they have a slang for brown folks living abroad called “kuttae” which transliterates to “dog”, but basically means “white man’s lackey”. She says most people hate them, but tolerate their antics because they generally have more money.
I know how badly immigrants from Africa and Asia have been treated in the US. What surprises me is that so many of the people working in the immigration office are descendants of immigrants. This got me thinking if one of the consequences of a US collapse (or even a major expulsion/exodus) would be these folks being forced to go back to the countries of their ancestors, and being treated horribly there out of spite / revenge.
Accent, mostly. And most Asian-Americans do not learn their respective Asian language.
I got the impression that they were referring to emigrants that naturalized and later repatriated, not necessarily their descendants. Also, just from my anecdotal experience, it seems that second-generation immigrants tend to learn both the native and host languages, and third-generation and beyond don’t know their native languages, or just bits and pieces. Source is my in-laws, as my wife is a second-generation immigrant (technically first but she was a baby when she came over.)
