The 2015 European refugee crisis created significant political, economic, and social challenges for European Union member states, prompting Hungary to adopt restrictive anti-immigrant policies to control refugee inflows. While previous studies have examined Hungary’s anti-immigrant discourse and the broader refugee crisis, limited attention has been given to the effectiveness of these policies in reducing refugee arrivals through an integrated perspective of securitization, populism, and public policy. Therefore, this study aims to analyze the impact of Hungary’s anti-immigrant policies on the reduction of the refugee crisis between 2015 and 2020. This research employed a qualitative descriptive design using a library research approach. Secondary data were collected from books, peer-reviewed journal articles, official reports, and relevant online publications and analyzed through qualitative descriptive analysis. The findings indicate that stricter asylum regulations, reinforced border security, and anti-immigrant political campaigns significantly reduced refugee inflows while strengthening public support for the government’s security-oriented migration policies. The study concludes that Hungary’s anti-immigrant policies effectively reduced refugee arrivals by combining restrictive migration governance with securitization strategies. These findings contribute to migration governance literature by demonstrating how security narratives and populist politics shape immigration policy outcomes and provide practical insights for policymakers facing large-scale migration crises.
