Home staff visited partner organizations in the Erasmus+ programme countries for the purpose of teaching or professional training. Within this project, UNIOS has also hosted staff and students from European partner higher education institutions. Activities realized at UNIOS by visiting students and staff were the same as of our outgoing participants. Incoming students were enrolled in study programmes and visiting guest performed teaching or cooperated with home staff within scientific or professional areas of common interests. The UNIOS International Relations Office is playing a significant role in establishment, promotion and furtherance of ties at international level.
