Assisted voluntary return (AVR) is a new approach to return of irregular immigrants aiming at combating unlawful migration, and thus strengthening national immigration systems. AVR lowers risks of the violation of human rights and preserves migrants’ dignity and safety. In addition, it carries fewer political and financial costs. AVR of irregular immigrants is an integral part of migration management in some European countries, including the Slovak Republic. This paper provides a general understanding of the issue of irregular migration and an analysis of policies and practices in assisted voluntary return of irregular migrants in the Slovak Republic. The paper concludes with a discussion of the major issues that need to be addressed in order to achieve sustainable and effective AVR management.
