{"product_id":"impossible-subjects","title":"Impossible Subjects","description":"This book traces the origins of the \"illegal alien\" in American law and society, explaining why and how illegal migration became the central problem in U.S. immigration policy--a process that profoundly shaped ideas and practices about citizenship, race, and state authority in the twentieth century. Mae Ngai offers a close reading of the legal regime of restriction that commenced in the 1920s--its statutory architecture, judicial genealogies, administrative enforcement, differential treatment of European and non-European migrants, and long-term effects. She shows that immigration restriction, particularly national-origin and numerical quotas, remapped America both by creating new categories of racial difference and by emphasizing as never before the nation's contiguous land borders and their patrol.","brand":"Princeton University Press","offers":[{"title":"Default Title","offer_id":50804444627176,"sku":"9780691160825","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/9539\/3512\/files\/imageloader_66d1cf19-5795-4a6e-adea-818af98b4e48.jpg?v=1790299749","url":"https:\/\/kuumba-47muwsn1.myshopify.com\/products\/impossible-subjects","provider":"Kuumba","version":"1.0","type":"link"}
