I’m visiting Manhattan and coming to realize that the global citizens here are disconnected from the rest of America to an extent that even people in the SF Bay Area aren’t.
For a large segment of the population, if it's not in New York, it doesn't matter.
The only other non-industry-specific cities that get any notice are London, then LA — sometimes.
Manhattan in contrast has a lot of global citizens who would have more affinity with other cosmopolitan cities like London and Paris than with the rest of America.
Interestingly enough, Houston Texas now ranks as the US city with the most international diversity. This is leading to all sorts of interesting things, like the development of new 'creole' cuisines (see the recent and rapid development 'Viet-Cajun' food).
Yes, and if you are looking to live in the US from abroad, good luck getting a work permit nowadays.
