The migrant´s integration onto the labour market is an important problem for every immigration country. Having a job constitutes the main source of revenue for immigrants and contributes to foster their integration inside society for example by facilitating access to decent housing, by fostering interactions with other people on the job place, by accelerating the learning of language in the host country. Active participation in the labour market is also necessary to assure that the population of the host country accepts more immigrants. The paper begins by examining immigrants´ skills. It then examines the situation of immigrants in the labour market and analyses the development of their employment and unemployment rates as well as the development of indicators relating to exclusion from the labour market - long-term unemployment. It continues by examining characteristics of jobs occupied by immigrants: types of contracts and level of qualification required for those jobs. It also examines the evolution of the over-qualification process. Two methods will be used to evaluate the results of the target group (i.e. immigrants) compared to the results of the reference group (i.e., those born in the host country): calculate the gaps between both results (presented in percentage points) and establish changes in percentage points in 2007 and 2017. Statistical data show that in every country of the EU, differences in the labour market exist between nationals and foreigners. Integration strategies in the labour market can help to guarantee equality of chances.
