The assignment content discusses the topic of immigration in the United States from the past few decades. It covers the literature review on legislating immigration, the experiences of Irish, Polish, and Chinese immigrants, the economics of rent and immigration, illegal immigration, and research methodology. The summary highlights that the US has seen a surge in immigration since 1960, with around half of its present population born foreign. The country has had a complex history with regards to immigration policy, with restrictions imposed on various groups, including Asians and African Americans. The Irish immigrants are noted for their successful assimilation, while Polish immigrants shared their experiences through letters. Chinese immigrants faced negative reactions from Native Americans and were restricted by the 1882 act. The economics of rent and immigration suggest that housing prices increased in LA during the period of high immigration. Illegal immigration was seen as a result of government restrictions on legal immigration. The research methodology used secondary sources, including publications and research papers.
