When I bridged from LPN to RN I went to work on a Navajo Reservation. Almost any reservation ( Dakota's, Arizona, NM, OK, etc.) will have needs for RN's. You can go to IHS.gov to search tribal and federal positions. Several of the non-IHS facilities have their own websites. Tuba City and Fort Defiance in Arizona, for example, have their own websites. I loved it. I worked in Fort Defiance.
