This study investigates the political engagement of Vietnamese immigrants in Poland on social media. It employs the typology of online political participation as a theoretical framework to determine the pattern of online in-volvement in the political sphere staged by the migrant group. Through analysing materials relating to political discussions created daily on an online community of the Polish Vietnamese, collected by doing netnography, this study shows that the political activism on social media of Vietnamese immigrants in Poland exists and varies. Vietnamese-migrant users discuss homeland politics and express views about political issues in the host country as well as other countries by creating non-mobilising posts (Information and Diffusion), while being inclined to produce posts with calls for action (Instruction and Promotion) to criticise social injustice and mobilise equality. This study also found a growing critical attitude towards homeland politics among Vietnamese-origin individu-als in the country. The findings have practical implications for associations and state actors in both the host and home countries to account for the evolvement of the migrant community.
