Well, I know that it`s not exactly the right place to ask but I really want to talk to someone who has the experience. I am looking for a well-structured undergraduate programme in English/ German /or both/... Where have you completed your LLB? Which university in Europe/UK/IRL would you recommend me? I am mostly interested in international business law and I hope to find a good university, which is in the first place not very expensive and offers accommodation. Thank you in advance for your help:)

If you're fluent in both English and German, I would recommend this UCL course:

LLB and Baccalaureus Legum

It's a double degree from UCL and University of Cologne. It enables you to be a qualified lawyer in both England and Germany, (although for germany you need to take the first state exam) too.

UCL is expensive though, but the opportunity to be dual qualified is pretty hard to pass up in my opinion.
