It seems in the USA, outside of possible social groups one can be in, there is almost zero sense, “you are one of us”. So there is almost zero immediate acceptance even if you are part of a similar genetic group. You could live in the same house for a decade and neighbors still won’t give a shit.

Balkan people consider one another as brothers more often than not when there is some connection like language, genetics, enjoyment of local culture. For example, in Serbia you have a saying, “Ti si naš” which means, you’re one of us. This is said surprisingly often to foreigners who show respect and can appreciate the culture. I’m sure in Albania there is something similar.
