if you can tell where you are living (city and state), people might be able to give your more relevent info (有的放矢). also, are you looking for an immigration lawyer or a lawyer in other specialties)
I am not sure about that. You may go to local INS office to find out. It may be hard to find a chinese immigration lawyer in AZ. You may try to find in Dallas, Houston, Texas from 世界日報
I put this up on top. Hope someone else can give you some suggestions.
