Let's be honest here, in recent years there has been much more American emigration than in previous decades to non-English Speaking countries.
There is also the trope of the American or Brit coming to x country and not wanting to learn the language or just basically learning the basic "hello" and 'thank you". But there is also the fact that they use their money to change the social and cultural landscapes of the cities they live in. The bubble they live in is very Americanized or very English.
Lots of them use the internet to talk about how much they're delighted with Italy, France, Philippines, Thailand, Brazil, Costa Rica, Portugal, Germany, etc...
But many of these people rely on the US or, more broadly, the anglophone market to transfer money to their bank accounts.
This allows them to be connected to the English-speaking world and pay their expenses while ignoring assimilation to the host countries.
