This paper examines the role of NGO support for migrants’ integration in the labour market through entrepreneurship endeavours. Drawing on the Resource-Based View and institutional theory, we formulate research questions on how NGOs operate in the institutional environment, organise resources and address the needs of their beneficiaries. We adopt the triangulation approach and analyse the national and EU legislation, media releases and 15 case studies based on interviews with NGO representatives operating in Warsaw, Poland's largest metropolis and the capital city with the highest proportion of foreign residents and a well-developed NGO base. Using the evidence from the case of forced migration from Ukraine to Poland following the Russian aggression in 2022, we extend the literature on institutional voids by demonstrating that they can be complemented by the wide range of NGOs’ activities.
