This however does not refer to international students studying at higher education institutions in Hungary.
The document entitled „Procedures regarding the rules of entering Hungary and special medical examination for non-Hungarian students” (see below) list the conditions of international students’ entering Hungary.
However from 1st September 2020 all countries are considered „red”, so there are no „yellow” and „green” countries.
Please make sure, that before travelling to Hungary you collected the completed „Annex 1. – Certificate” from IRO-UM.
Further updates will soon come.
