How to find an American boyfriend since I am a Chinese girl?

I am a traditional Chinese girl and works in Singapore as a nurse,I always want to find an American boyfriend in SG.However,it seems quite difficult for me. I prefer staying at home or going out with my Chinese staffs.in SG,I just feel like I am always alone most of my time.Working is my biggest theme but I do not want to be like that.most of my patients are also from US.I just like American guys who can also improve my English.i want a guy who also likes Chinese girls and interests in Chinese culture.Please be sincere.
