@OP - 2 things:
1. I was living back in SFO and my game was perhaps at its sharpest back then.
I approached at least 10 girls daily. I had hundreds of numbers in my phone.
And you know what? I did not get laid nearly as much I would have liked out there.
As far as I could tell, the people who were really cleaning up in terms of pussy were my BJJ training partners who bounced/bartended in the clubs and dudes with huge social circles.
The logistics there are heinous, the attitude and feminism rating is off the fucking dial and despite the huge queer population, it's still a sausage fest out there.
I think what makes chasing American tail so uniquely daunting is the fact that even when you're horny as hell, every word out of an American girls mouth is like boner kryptonite. It's like you have to hurry up and fuck her before her disgusting personality completely turns you off. Apropos:
All this is to say, it's not that you don't have game necessarily but it's just that the odds are completely stacked against men in the States and in the bay area specifically unless they manage to carve out a clever pussy-getting strategy.
And even then, I don't know how worth it it is...
2. Since you're in business, I suggest you look at the potential marriage as a business transaction.
On the one hand you'll be (presumably) getting your needs met: sex, division of labor vis-a-vis cooking/cleaning/sex, etc. And on the other hand, your gal will have the house, the well-to-do hubby and maybe some kids.
I think that's generally a pretty good deal assuming:
A) there's no way this broad can ever get her hands on your assets, and...
B) you can fuck around with other girls on the quiet tip.
What complicates this otherwise good bargain is the fact that if you import a chick from EE or SEA to the states and especially to a hyperbolic, keep up with the Jones' environment like the Bay, your wife will probably lose her charm and sweetness sooner rather than later.
The commie/gay/feminist California laws will also probably enable her to completely rape you financially if the shizzle ever hits the fan (and if kids enter the picture).
And once she has her documents in order, will probably start looking for an upgrade in husband. Not that there's anything wrong with you but women are always looking for a better deal.
So if your main drive and passion is tech and seeing the fruits of your hard work ripen into a good living and making a small dent in the universe, it wouldn't be prudent to put it all at risk just for the sake of getting your girl situation squared away. Not to mention, even when you think you've got the wife situation locked down, you'll be dealing with whole another big ass can of worms. Good luck.
