The rights of a EU citizen
A citizen of one of the European Union Member States is at the same time a European Union citizen. Therefore, Polish citizens are at the same time European Union citizens. Acquiring EU citizenship happens automatically when the citizenship of any Member State (for example Poland) is granted, with no need to meet any other requirements. One cannot acquire EU citizenship without acquiring the citizenship of one of the Member States. Similarly, it is not possible to renounce EU citizenship without renouncing the national citizenship of a EU Member State.
