This diploma thesis focuses on the integration of Ukrainian migrants in the Czech Republic. In connection with the increasing emigration potential of the Republic of Ukraine due to the ongoing civil war, the thesis will be an analysis of the Czech Republic's current integration policy towards foreigners from third countries with an emphasis on migrants from Ukraine. Significant changes in integration policies started after the accession of the Czech Republic to the EU, contextual documents and other public policy measures aimed at systematizing the integration of migrants from third countries. Thus, the aim will be to analyze publicly-relevant documents, which outline the essence and determinants of the Czech Republic's integration policy towards migrants from third countries. The Czech Republic responds sensitively to migratory trends, but more emphasis put on current immigration from Ukraine. Therefore, another goal will be to unveil the integration policy exclusively towards the Ukrainians in the Czech Republic. Finally, the ultimate goal is to understand on the basis of the interviews, what barriers the Ukrainians have in the Czech Republic for integrating into the host society. The life course theory helps to identify what trajectories they choose to integrate in their individual dimensions.
