University of Tulsa is good for that and it is easy to get into. It is the only school I applied to and I applied in June 2 months before school started and got 17,000 scholarship. The school staff was great and when I visited the campus a lot was mentioned about Native American's and they even have a Native American Law Clinic so I would recommend them if Native America Law is what you want to specialize in. I do not want to specialize in it and did not go, because Oklahoma is not for me. However, if Native American Law is for you then I would consider Tulsa.
