IRCA's impact on the occupational concentration and mobility of newly-legalized Mexican men

We examine the occupational concentration and mobility of a group of unauthorized Mexican men who received amnesty under IRCA to shed light on the role of legal status in the assimilation process. Initially these men are concentrated in a small number of traditional migrant jobs. Although their occupational mobility rate is high, it partly represents churning through these same occupations. When we consider the direction - either upward or downward - of occupational change, we find that English language ability and the characteristics of the occupation, itself, are strongly correlated with mobility before legalization. After legalization, few characteristics surpass in importance the common experience of having received amnesty.
