The financial aspect can be of major importance while abroad. Factors such as length of stay, cost of living abroad, any tuition fees, travel costs, etc. are to be taken into account in financial planning.
For stays abroad, there are different funding and scholarship opportunities, depending on whether you want to study, do an internship, write a thesis, or take a language course abroad.
For a list of scholarships and financing opportunities for stays abroad, see also the OSCA portal.
