Once the Invitation letter received, a foreign citizen must submit documents to the Consulate of Ukraine in the country where the foreigner resides to obtain a D-13 visa according to the list provided on the Embassy's website. Documents on prior education must be officially translated into Ukrainian and certified the way accepted in your country (legalized or stamped with an Apostille stamp) before submitting to the consulate. These documents must be officially recognized in Ukraine so that the university could issue a diploma after your graduation.
