Every country has ex-pats, its not a British thing, the Chinese have " China town " in various cities around the world
When I Lived in Sydney, you had communities of ex-pats from various countries, I was involved in the Lebanese community as I was dating the daughter of a Lebanese immigrant, it was very tight knit, the older generation refused to speak to me, would often abuse me in arabic, it was funny, I would be abused by them for being white and she was abused by Australians for not being whitestill makes me chuckle
