With the annual number of immigrants to the United States at an all-time high, the debate over immigration has reached a fevered pitch. Do today's immigrants come to this country just to go on welfare? Will immigration forever change America's ethnic, cultural, and political landscape? Some see unrestrained immigration as the lifeblood of the world's most successful society, while others have called for closing the borders entirely. After the introduction, which examines the historical debate over immigration, the book looks at the current spectrum of economic, political, social, and legal issues related to immigration into the United States - from compelling arguments for limited immigration to forceful arguments for open borders.
