Each country has its own rules regarding entry visas; student visas; visitors visas and so on. It is essential that you clarify the requirements for study in your country of choice, based on your passport of your country of origin. Most university websites provide this information for students. Nevertheless, it is your responsibility to make sure to have the necessary documentation to be eligible for study in that particular country.
To be eligible for semester three and four abroad, all students must have achieved the full 60 ECTS from semesters one and two. Any student that does not achieve the 60 ECTS from semesters one and two will not be allowed to go abroad.
Students who withdraw from the mandatory double degree arrangements for semesters three and four, after nominations have been made and after tuition fees are due are fully responsible for full payment of any fees or charges incurred.
