In Almost Home, H. B. Cavalcanti, a Brazilian-born scholar who has spent three decades working and living in the United States, reflects on his life as an immigrant and places his story within the context of the larger history of immigration.     Due to both his family background and the prevalence of U.S. media in Latin America, Cavalcanti already felt immersed in U.S. culture before arriving in Kentucky in 1981 to complete graduate studies. At that time, opportunities for advancement in the United States exceeded those in Brazil, and in an era of military dictatorships throughout much of Latin America, Cavalcanti sought in the United States a nation of laws. In this memoir, he reflects on the dynamics of acculturation, immigrant parenting, interactions with native-born U.S. citizens, and the costs involved in rejecting his country of birth for an adopted nation. He also touches on many of the factors that contribute to migration in both the 'sending' and 'receiving' countries and explores the contemporary phenomenon of accelerated immigration.     With its blend of personal anecdotes and scholarly information, Almost Home addresses both individual and policy-related issues to provide a moving portrait of the impact of migration on those who, like Cavalcanti, confront both the wonder and the disorientation inherent in the immigrant experience.
