Try to see whether your university can introduce you to the university in Geneva's internship programme. Or approach them directly, they have an office that acts as an intermediary for interns. And if they won't help you because you don't study there, they may still be able to give you some tips on what to do. Good luck!

Thank you very much Cees K. I took your advice and talked about this at my school. Unfortunatelly they just want to sit on their asses and do nothing to help... I'll go directly to have a chat with someone from the University of Geneva and hopefully they will help. If not... I will probably go from door to door and ask if someone is in need of a romanian engineer who wants a 3 month period interNship*/fellowship.
