The goal of this inquiry is to help students develop their thinking in terms of continuity and change through learning about US immigration policy actions and their effects over time. By examining whether there is anything new about current immigration policy debates, students compare and contrast the discourse around immigration at three key moments in US history—the passage of the Chinese Exclusion Act of 1882, the Immigration Act of 1924, and the Immigration Act of 1965—with the current immigration policy. Students need to develop a deep understanding of each of the three policies in order to write a thoughtful argument that analyzes continuities and changes in perceptions of and policies regarding immigration throughout the post–Civil War period of US history.
