I saw an asian cooking programme the other day and they used an ingredient called SWALLOWS NEST what is it????

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?
