Happy New year to you as well. Each country in tyhe EU has its own regulations and requirements comcerning the recognition of the diplomas. Depending on the country that you want to live you should check with the authorities. Usually it involves a list of course that you had at your university in order to compare them with the course of the EU country. After that if there are differences it may require for you to give exams and/ or follow a few courses at the EU university.
