The seventh edition of this pioneering casebook continues its tradition of comprehensive coverage, with problems and exercises that allow students to hone skills as counselors, as litigators, and as policy advisors. At the same time, the casebook situates immigration and citizenship law within broader contexts of constitutional and administrative law as well as current political debates. This new edition is reorganized for more efficient coverage, with an introductory chapter on immigration history; treatment of unauthorized migration alongside lawful admissions; consolidated treatment of inadmissibility and deportability; reworked materials on state and local enforcement; and thorough redesign of materials on criminal convictions.
