The present Master’s thesis presents the issues of employing foreign citizens in the Republic of Slovenia and certain other countries of the European Union (EU). Its focus lies primarily on the employment of third countries’ citizens. Each EU member state has its own process of employing third countries’ citizens. Nevertheless, due to the common European legislation and numerous directives the process is becoming more unified. The thesis presents relevant regulations in the Republic of Slovenia and describes the conditions foreigners must fulfil in order to obtain the single residence and work permit. Primarily, it is a description and criticism of the changes brought about by the Slovenian Employment, Self-employment and Work of Aliens Act. Furthermore, the EU directives which significantly influenced the regulation of the employment of foreigners in the EU and the Republic of Slovenia is briefly described. In order to discover possibilities for improvement in the Slovene regulation the present thesis also presents the employment of foreigners in Austria, Germany and the United Kingdom. The thesis seeks to find the answers to the questions why the mentioned countries predominately want a highly qualified workforce and what methods they use to attract these workers.
