Yes. I mean my parents were immigrants from another country and both their sons married Americans (not even white Americans, but Americans nevertheless) and move to the real 'innards' of America. Also, I have nothing in common with people from my parent's country. Even the food we like from the 'home country' is completely different. I much prefer American-styled ethnic food from my parent's country than anything you'd get there.
Unlike most European countries or even Canada though, immigrant Americans consider themselves ... Americans. I mean... my parents are honestly pretty hard core trump supporters and contrary to popular belief, they've been very welcomed at all these supposedly 'racist' events.
> It is something tourists comment on, that they stumble into different neighborhoods and feel they are in a totally different place. There are whole sections of my hometown which basically operate in a different language and where everyone has moved out. It doesn't seem like integration to me. I think people just move around each other in America and can afford to do so more.
Sure, in the big cities where there are lots of immigrants it can certainly be like that. In the more provincial parts of the country you can go -- as I did -- to Oktoberfest celebrated in an old German town, except all the people who live there are now hispanic, philipino, or mixed whatever and are all happily doing the Polka and drinking beer while saluting the American flag.
Also, typically in those 'ethnic' neighborhoods you speak of... people are very patriotic. For example, my brother married into a big hispanic family and some of the older generation definitely speaks Spanish mainly and a lot of the town they live in is primarily Spanish, but they're incredibly patriotic and love America.

I totally get why tourists might find it weird, but as a native born American, I stumble into many ethnic enclaves in the US and feel pretty at home. Most people aren't used to that.
