This basically skips the daunting process that's H1B lottery.
What city is the best to find someone who is/has:
Open to new experiences and concepts (museums, art, dancing, music) <— literally the “openness to experience” on the big 5
High cognitive ability
Into meditation, yoga and exercise?
Somewhat into gaming and anime? (Optional)
Somewhat of a programmer or (game) designer/related (optional)
It's really hard to get that marriage green card though, you're looking at many months of paperwork on top of building a successful relationship and committing your life to someone. I think it'd be a lot easier to get a job at a big company in the US and come over on an H1B, or build a SaaS business wherever you live now
Generally, any big East Coast city. NYC, Atlanta, Washington DC, Chicago, and Boston would be top of mind.
The United States has an adult population of 258.3 million, so it's likely you'd find someone to fall in love with if you're really looking.
I have some experience here, I have a double digit amount of family members who came to the US to marry into my family, including my brother-in-law. With one exception they are all very happy marriages, the longest lasting 3 decades. There were some who were definitely were looking to marry Americans to immigrate, but the relationship is still real.
L1B visas can also convert to green cards at some point, but I have no idea how easy that is (probably not easy at all).
False. L1B is not related to Green Card in any way. You can get the employer to petiton you for a green card while working on L1B.
