You often will not have any trouble finding English versions of EU materials since English is one of the official languages of the European Union. The EU currently has 24 official and working languages. The reason for this is that the EU believes that all EU Citizens have the right to access EU documents in the official language(s) of the Commission. Since the various members have different official languages in their own countries, this had necessitated providing translations of materials into many different languages. However, if there is a circumstance where translation is required, you can use some of the tools listed in order to understand the documents.
