Hey,
I'm white, so white I am practically transparent in the winter time, but I think I can help you with the asian-guy <-> white chick interrelations.
Generally speaking, asian guys have a hard time snagging a white woman, but it isn't about looks or general racism. It's about attitude. When you deal with *most* (not all) white chicks, they look for your attitude towards them. Hey, I know this for a fact. Try to be honest, relaxed, funny, and most of all respect what they think. Some of my indian co-workers (FBO) have a hard time at that. Others dont. I hate to say it but the society that has evolved here in the USA is more based on how you act than how you appear. And maybe that's a good thing (what's his ugly-face even married Julia Roberts!).
Just be cool, be funny, and be nice. If you see a girl (who is available!!!!) and she tickles your fancy, then don't rush it, don't force it. Be her friend first, and maybe lover second. The last thing you want to seem is pressing, or just pushy.
On a slightly *darker* side...
Racism in this country still exists. Some people will tell you it doesn't, but that is just not true. Don't let it get you down, since (being a minority) you will probably be the victim of it eventually, one way or another. There are just too many rednecks in this world. But the vast majority of us just want to kick back and kill a brew with ya'all. Don't judge us by our radical minority. The USA is the melting pot of the world. Welcome to the home-brew.
G'luck, and I wish you the best!
