This study analyzes the extent of utilization or underutilization of the education and training brought by different groups of skilled Cubans and ascertains to what extent their competencies were transferable under conditions existing in the United States since January 1, 1959. Through the survey, the statistical analysis, and interviews with Cubans throughout the United States, it was found that occupational adaptation to the new environment is a function of legal status, self-employment, availability and length of retraining programs, attendance at schools or universities, state and local requirements to practice a given profession, license or higher degree in the United States, extent of ability to continue in former profession, and the common productivity variables of age and sex.
