My study examines Hungary’s migration management, in the framework of criminal policy and the theory of deterrence. Hungarian public service bodies have a two-fold task, since they must act in accordance with a given situation and be prepared for the expected future impact of migration. In addition, they must carry out all this by satisfying citizens’ expectations and maintaining public safety. I present the change that took place in the Hungarian public service bodies, public administration, law enforcement services and the Hungarian Defence Forces as a result of the mass immigration of 2015. I placed the police and public administration at the centre of attention, while also focusing on complementary police forces.
