how to get asian american business directory?

Answer 1

Do you mean a directory oa Asian American business people in the US or a directory of Asian companies who do business in America?

Check with your local library. They have amazing amounts of reference material, for free, and will help you find what you need.

Answer 2

There is no Asian American business directory. Asians are not like Hispanics who all speak the same language-Spanish. You could get local Yellow pages in big cities in Chinese, Japanese, Korean, etc. that list local businesses.
