The recognition of diplomas, academic degrees and titles of Ukrainian citizens in Poland in the time of full-scale Russian military aggression against Ukraine has become quite an important issue after 24 February 2022. Diplomas and degrees obtained after 20 June 2006 are not recognized on the basis of international agreements, since nostrification of the relevant diploma or degree is required, on the basis of which a certificate of recognition of the relevant diploma or degree as equivalent to the Polish one is issued. Unfortunately, there is no publication in the Polish literature that discusses the process of nostrification of foreign diplomas and academic degrees along with practical aspects in this regard. Therefore, the article aims to present the criteria for the recognition of diplomas and academic degrees obtained in Ukraine and to analyse the most significant challenges that Ukrainian citizens may face in the procedure on recognition of their diplomas and academic degrees.
