The following article contains an analysis of the formation process of the Ukraine war migrant’s protection model in Poand and its characteristic features, as well as the political, social and cultural context of its implementation in the public and non-public aid system. The results showcase the particular value of citizen involvement in the process for the efficiency of the public assistance system. Additionally, potential opportunities to use the Polish experience in other countries offering protection to migrants are estimated, alongside a summary of strong and weak points of the Polish migrants reception system.
