東岸印地安事務組織(The Eastern Association on Indian Affairs，AAIA)目地是幫助普魏布勒印地安人爭取權利。在1920、1937年和其他相關組織合併，於1946年改名為美洲印地安事務組織(Association on American Indian Affairs，AAIA)，在1957年成為非營利聯邦組織。AAIA的主要目標，是要增進美洲印地安和阿拉斯加原住民福利，從以下幾點來實行：(1)保存他們的文化和語言；(2)保護他們的行政權利、憲法權、法律和人權，還有自然資源；(3)提升他們的健康、教育、經濟和社區發展。

The Eastern Association on Indian Affairs was started in New York in 1922 to assist a group of Pueblo people who were fighting efforts to dismantle their pueblos. In the 1920''s this organization merged with a like-minded entity, and again merged with a third entity in 1937. In 1946, the name was changed to the Association on American Indian Affairs. The mission of the Eastern Association on Indian Affairs is to promote the welfare of American Indians and Alaska Natives by supporting efforts to: 1) sustain and perpetuate their cultures and languages; 2) protect their sovereignty, constitutional, legal and human rights, and natural resources; and 3) improve their health, education, and economic and community development.
