A number of changes of law came into force effective from 27 April 2019 in connection with the implementation of the EU Students and Researchers Directive (2016/801). Most importantly, a new certification process has been introduced for schools and universities wishing to host a foreign student or researcher. A simplified notification procedure and a work permit exemption has also been introduced for students and researchers legally residing in other EU countries who move to Poland for a limited period under the terms of so-called ‘student and researcher mobility’.
