This thesis investigates the role of private technology companies in shaping migration governance through digitalization within the European Union. It addresses a scholarly gap by not only focusing on states and EU agencies, but specifically on high-tech companies involved in the migration management and border control procedures. The central research question for this thesis is: ‘‘What role do private technology companies play in shaping migration governance through digitalization in the European Union?’’. It hypothesizes that such companies are not only technical providers, but co-designers and influential partners in border management. To answer the research question, a qualitative research design has been applied, using desk research and content analysis of secondary sources. The analysis has been guided by the following theoretical perspectives: Public-Private Partnership (PPP) theory, Surveillance Capitalism, Securitization Theory, and Technological Determinism. The findings indicate that private technology companies have substantial influence over how migration governance digitalized, shaping policy implementation beyond simply executing. It aims to contribute to the public administration and migration governance literature by analyzing the implications of outsourcing core state functions to profit-driven actors, particularly in terms of transparency, accountability, and migrant rights.
