Honestly, I don't think that I'm the best guy to give dating advice. But, I do see with many East Asian guys who come to this country wanting to get with American women, that their biggest mistake tends to be that they only hang out with other people from their country and wonder why they can't meet any American women.
If you want to develop a real relationship with a Western woman, then your best bet is to actually live here. But, if you do, make sure that you go out and meet some Western people.
If you're smart, then maybe you can come here to work in the US in the IT industry. There's a lot of Asian foreigners at my work, so you wouldn't be really stick out.
But, getting an H1B1 visa is pretty hard. It's easier to obtain an H1B1 visa when you already have a student visa, because businesses don't have to fill out the paperwork for you right away. They can put you on a trial period before they decide to sponsor your worker's visa.
And, if you choose to live somewhere in the US, the choices are really open. But, every location has its pros and cons. People in New York and the New England or California region tend to be more accustomed to foreigners, but the cost of living is really high. This can be a really big problem for you, considering that you're used to things being cheaper in China.
Then there's the South. The people here have been characterized as being racist and close-minded to outsiders but racism isn't really unique to the South and you might see less of it in big cities. Plus, the cost of living here is much cheaper than up north which is always a bonus.
However, if you're not used to having to drive a car very often, you will definitely have to get used to it if you move to a new city or a suburb. And, I when I say "new city" I mean most cities in the South and any city whose population didn't really boom until after WW2.
On the other hand, New York and New England cities are different, because they were already huge before cars were around. So, there's a lot of nice public transportation for you to use and you might not have to get a car, but, again cost of living is high.
I used to work in Washington, DC. And, their WAMA metro train was really big. Their city train system is 2nd most used in the country, next to New York. And, it was for a reason, because the roads were packed during rush hour. But, DC is really expensive to live in.
On the other hand, I also used to live in Atlanta, GA as well. And, their city train system was mostly used by tourists. It really only took you to the big tourist destinations and using the train wasn't a feasible means of transportation on your way to work.
However, their Buckhead Uptown Connection bus system is still available. I had some Indian co-workers who didn't own a car rode the bus to and from work, so you might be able to get by without a car in a new, Southern city if you do your research.
Anyways, good luck.
