Immigration is a topic that bears global attention, especially in the context of globalization, which generates more and more international trade and population movements. Since the beginning of the 1990s, two main strands of the literature showed up. One claimed that immigration does not influence the labor market (Card, 1990; Altonji and Card, 1991). The other stated that the natives will get worsen due to an underestimation of immigration impact (Borjas et al., 1997). Subsequently, studies on labor market employment rates, unemployment, and wage levels in different regions and countries have been conducted and have yielded different results. France is one of the most historical countries of Immigration in Europe. The study's purpose is to investigate to what extent immigrants will influence the employment of natives in different occupations. The census data for 100 French regions in 2008, 2013, and 2018 are examined by a fixed effect model with clustered robust standard errors. By dividing the natives into six categories of occupation, this study does not aim to get a general conclusion on the overall labor market but to discuss at the occupational level separately. The findings show that immigration negatively affects native employment for most occupations, while for farmers, the influx of immigrants generates motivations for natives, and for intellectual occupations, there is no effect.
