What are the international reculations of using the acamidec resources of Finland while studying in EU/Overseas? What do you recommend for the library to visit whilst in the country?
I'm afraid I don't quite understand your question. What exactly do you mean by "academic resources" and "regulations"? If you mean the library collections of the Finnish university libraries and the right to use them, so basically they are open for everybody and it is also possible to request interlibrary loans from their collections, even to be sent abroad.
If you are staying in Finland, there are many libraries worth visiting. Depending on your special interests, I would recommend e.g. the following:
You will find the contact information of all Finnish libraries at http://www.libraries.fi/en-GB/
