I could not agree with you anymore!
If you are fair, just expect what you paid for, American people are more responsible than most CHN, since they grew up in a society that appreciates reputation and credibility over any tricks. They won't do anything on the edge of law. So you are always safe and confident. Sometimes you may get more if people get to know each other.
If you are afraid of language and commnications, CHN seem to a better choice? But most of them know that much better than you, and some will take advantage of that. They know what you would think due to the same culture.
No matter what, count on and select from referrals, from people around you, not online except BBB (http://search.bbb.org/search.html). That's why my service for real estate, mortgage, family doctors, imm lawyer, etc. all Americans. Even though sometimes I have difficulties get understood, they are patient and work with us together.
A really good American lawyer to recommand: Priscilla (PJ) Cortez (Priscilla (PJ) Cortez), she represents myself and some other clients from companies. Her responses are always quick(same day),brief(
I believe in better business should be rewarded and encouraged, and tested over time.
