This book is truly awful. I don't know what her publisher was thinking by letting this book get out. The tone: Nasal. The language: Sociological jargon. The argument: Garbage. Save a tree and find something better.

Mae Ngai's ambitious book compels historians and general readers alike to critically reassess traditional understandings of and approaches to U.S. immigration. Much of the histories on U.S. immigration and immigration policies have told a similar tale. The United States, the narrative goes, has been tainted by a long history of exclusion, a blight on the nation's democratic tradition that was only recently removed with the passage of the Immigration Act of 1965. Such a narrative not only reaffirms the myth of American universalism, but also consistently fails to produce any new critical knowledge about U.S. immigration and U.S. history. Impossible Subjects differs from these other works of immigration history in this important respect: it proceeds with the conviction that the United States was never a "nation of immigrants."

Ngai examines the era between 1924 and 1965, an unconventional periodization in immigration history that situates the 1924 Johnson-Reed Act (usually signifying the end of one regime) at the beginning of her study, and the Immigration Act of 1965 (usually signifying the beginning of another) at the end. Beyond simply filling a historiographical gap in immigration history, the focus on this period of immigration restriction enables a reevaluation of U.S. immigration laws, and more broadly of U.S history, on several levels. First, it demonstrates that restrictionist policies did not merely function as a tool for exclusion, but more, it created-through a racial and geographical remapping of the nation-new categories and concepts deeply implicated in race that defined the spaces and limits of national inclusion. Second, these categories and concepts, most notably "illegal aliens" and "national origins," are not natural or fixed conditions and markers, but are the product of positive law that, when scrutinized, reveal the ways in which its uses have shaped and defined the United States in the twentieth century, particularly its ideas and practices about race, citizenship, and the nation-state. Finally, this periodization allows for a reconfiguration of immigration history beyond a nationalist framework. By suggesting that the making of modern America rested on the exclusion of nonwhites from the geographical and ideological borders of the nation during this regime of restriction, the book argues against the normative telos of immigrant settlement, assimilation, and citizenship as the defining narrative of American history, a narrative that is confined to the nation-state and that invariably reproduces American exceptionalism.

By charting the historical origins of the "illegal alien" and the genealogy of immigration laws that have consistently reproduced it, Ngai has ultimately written a stunning history that goes far beyond narrating the history of U.S. immigration restriction. It is a book that deserves to be read widely.

IMPOSSIBLE SUBJECTS, written by Mae Ngai, is the best of recent books on the 20th-century American history of immigration. She reveals that the problem of "illegal immigrants," which has been regarded as one of the most serious problems since the late 20th century, is indeed a legal construction. According to the author, immigrants from Mexico were drawn into the U.S. Southeast because the Southeast political economy, especially agri-business, raised need for the massive wave of low-wage immigrant workers and at the same time defined them as the racially "foreign" people who were rendered alien to America, which was defined as the nation of Caucasians. What enabled the American Government and people to attach racialized foreignness to the Mexican immigrants (and, inevitably, American citizens of Mexican origin) were Immigration Acts, border policing, and discriminatory control of visas.

Mae Ngai argues that positive laws concerning immigration policy have constructed the category of "illegal aliens" from Mexico, and the implementation of the laws by Border Patrols and INS has reinforced the labeling of racially alien immigrants. She bases her analysis on the critical legal theory which suggests that laws constitute social formations. Her usage of the new legal theory in her inquiry into the American immigration history is highly excellent and persuasive.

The historical analysis of the immigration problems in this book seems to be applicable to other countries' history. For example, Ngai's insight shall give light to the recent Japanese conservative media discourses on the "illegal migrants" from China, South Korea, and Latin American nations which describe the undocumented migrant workers as illegal, criminal and, in case of women, prostitutes.

I would have dedicate five stars to this book if its text were easier to read (it is possible that I felt this book's text not very easy to read because I am not of a native-English tongue).
