This article provides an analysis of the employment and occupational attainment of immigrants in Chile. We used data from the Chilean Household Survey for the years 2013, 2015, and 2017 and compared the probabilities of being active, employed, and informally employed among immigrants and native-born Chileans using logistic regression models. We then analysed the occupational attainment achieved alongside the role of informality in constraining upward mobility by means of multinomial logistic regression models. After controlling for socio-demographic confounding factors and the role of time since arrival, we found evidence that immigrants are not at a disadvantage when compared with natives regarding activity and unemployment. We found evidence of diversified assimilation, which depends on both the migration origin and gender. Employment informality among Latin American immigrants appears to reduce their access to higher-skilled and high-quality jobs when compared to formal migrants.
