What are the obstacles new Asian immigrants face when they operate small business in a minority community?

so far, I have language barriers, unsafe minority neighborhood, and little money.

What kind of risks/obstacles do new Asian immigrants face when they operate a business?

I’m working on my homework right now:
What kind of risks/obstacles do new Asian immigrants face when they operate a business in a ethnic community? Los Angeles, Long Beach, San Francisco, etc.
The only few answers that I can come up with are:
- racism- racist people won’t buy the Asian stores
What else?
