I can't ever become a US Citizen, but can I become a cultural American from a distance in Amsterdam instead, or still viewed as a foreigner?

It was always my goal to leave my own people, Dutch, formally and legally join and make the US my new home and American people my new own people and become 'one of them' instead.

However, as that is not possible (I can't get the Green Card and residency), can America come to me in The Netherlands instead?

I can attend the LDS Church in The Netherlands, watch CNN, Fox & NBC News here on TV, get all the US fashion brands, confectionary, food and drink products and film products exported here, join the Dems or Republicans overseas, follow an NFL club, sign up to a US think tank or policy institute as a member, buy Time and Newsweek, get all the email alerts, drive a Ford car, wear Levi's and Dockers and eat out at TGI Friday's.
I can also visit the US on holiday as well.

Is it possible to go native and be an American without holding their passport, citizenship and living and working in the USA, or would I still be considered a 'foreign outsider' and hence 'not one of them'?

I'm already married to a Mauritian so can't marry one of them either.

Any thoughts?

Why you'd want to do any of those things is beyond me - TGIFriday's especially. And it would make you look like a tool at home most likely - especially given Trump has been destroying America's brand abroad.

If you have any skills you might be able to get a green card with time. You can also get a job with a company in the Netherlands with significant presence in the USA.

You are not American. You will never be American. If you want to leave the Dutch so much, why did you move back there from England? You need to see a psychiatrist. Seriously.

It's probably not a great time to act like an American anywhere in the EU. But do whatever you like.
