This cross-cultural research study, on 82 randomly sampled male urban Spanish speaking immigrants in the District of Columbia, analyzes the relationship of the immigrants' native educational attainment to occupation and to income, to assess their manpower utilization, and to make recommendations for manpower training programs. Data on economic and social characteristics found the immigrants to be more similar to the black population rather than to the Spanish speaking and white populations in the District of Columbia. A positive relation is said to exist between native education and economic success, as measured by occupation and earnings, with the first job in the native country mediating between education and economic success. Immigrants are found to be underutilized in their U.S. occupations as compared with those held in their native countries, and those immigrants having completed a secondary education were found to be under represented in white collar positions when compared with nonimmigrants. The development of policies leading to facilitation of the tendency of immigrants to shift from the service occupations to blue collar occupations which conform to their previous experience is recommended. Chapters include background and related research, sampling procedures, characteristics of the samples, education and economic success, manpower utilization, and conclusions and recommendations. Instruments utilized are included in the appendixes. (Author/AM)
