US social work model

[luutuanh]

Dear all,
I am from Vietnam. Now, I am working on a research about US socialwork model and Vietnam social work model. It is not easy for me to do that research because I am a new comer in this field.
I am very grateful if you tell me about the US social work model or tell me how I can find those kind of information. My research is to compare the difference between Vietnam model and US model.

Thank you so much,
Tu Anh
