reforms later became law through the Immigration and Nationality Act of 1965, which dramatically shifted the source of immigration from Northern and Western European countries towards immigration from Latin America and Asia. The policy change also shifted the emphasis on the selection of immigrants in favor of family reunification. The late president's brother, Senator Edward Kennedy of Massachusetts helped steer the legislation through the Senate.

He expressed concern about the plight of the Seneca and directed government agencies to assist in obtaining more land, damages, and assistance to help mitigate their displacement.
