Undocumented Dominican Migration is the first comprehensive study of boat migration from the Dominican Republic to Puerto Rico. It brings together the interactive global, cultural, and personal factors that induce thousands of Dominicans to journey across the Mona Passage in attempts to escape chronic poverty. The book provides in-depth treatment of decision-making, experiences at sea, migrant smuggling operations, and U.S. border enforcement. It also explores several topics that are rare in migration studies. These include the psychology of migrant motivation, religious beliefs, corruption and impunity, procreation and parenting, compulsive recidivism after failed attempts, social values in relation to law, marriage fraud, and the use of false documents for air travel from Puerto Rico to the mainland United States. Frank Graziano's extensive fieldwork among migrants, smugglers, and federal agencies provides an authority and immediacy that brings the reader close to the migrants' experiences. The exhaustive research and multidisciplinary approach, highly readable narrative, and focus on lesser-known emigrants make Undocumented Dominican Migration an essential addition to public and academic debates about migration.
