I think Melania is from Slovenia.
Slovenia offers free tuition at public universities to citizens of Slovenia and the European Union (EU). It also offers free tuition to citizens of Bosnia and Herzegovina, Montenegro, Kosovo, Serbia, and North Macedonia.
Students who are not eligible for free tuition may pay as little as $2,100 per year for a bachelor's degree program. Slovenian universities may also charge American students tuition for undergraduate study. However, there are opportunities to earn a free doctorate qualification.
