The United States is home to an estimated 11 million undocumented immigrants. The options for dealing with this sizable population are controversial; the financial, legal, and social impacts of unauthorized immigration stir strong feelings on all sides of the issue. This book looks at current approaches involving border security, deportations, and allowances for people who arrived here as children, as well as ideas ranging from tougher immigration laws to issuing more and longer-lasting work visas.
