Historians are currently investigating the long-lasting impact of the Immigration Act of 1965 on politics, social movements, culture, and civil rights during the late twentieth century. In this unit you will join them by evaluating a selection of primary sources to grapple with important questions regarding how the Immigration and Nationality Act of 1965 impacted the lives of migrants coming to the United States and whether this act offers an example of the importance of immigration policy for understanding changes throughout recent American history. Through the careful examination of the documents in this unit you will develop important historical thinking skills such as critical analysis, reasoning, and comparison that will help you answer the unit’s central question: What do the debates surrounding the bill indicate about the political, economic, and social changes occurring in the United States during the mid-1960s?
