One cannot start a discussion of those who seek to belong without first knowing what belonging is. So, in this casebook, the authors start with citizenship. Their theme is membership, and that theme is reflected throughout. Significant changes include deleting the chapter on the concept of "entry," folding the relief from deportation chapter into a general chapter on grounds of deportability, adding the judicial review materials to a new chapter on removal procedures, and creating a new chapter on undocumented immigration.
