Language Integration of Adult Immigrants in the EU in the Context of Policy Measures

The EU has had an action plan for integration and social inclusion since 2016 (European Commission, 2020), but national strategies vary between member states (Vareikyté, 2020). In line with this, the Migrant Integration Policy Index (MIPEX) (Solano and Huddleston, 2020), which measures countries' success in integrating migrants, gives countries very different scores. As knowledge of the host country's language is key to immigrant integration (OECD, 2022), this research aims to examine the relationship between language integration policies and integration success as measured by the MIPEX. In this way, the present research can provide a new perspective on successful integration by linking successful integration to host country policies related to language integration.
