Switzerland has 4 official languages and they talk about adding English from time to time. It has long been a popular work destination for foreigners (like me). Currently, 27% of the population is foreign.

They come from Africa (French speaking cantons), the Middle East (all cantons), northern Europe (German-speaking cantons), southern Europe (Italian-speaking cantons), and a variety of other places. Geneva and Vaud are an international as places can get.
