A clear certificate can look self-explanatory, but INZ needs to read every element in English: the issuing authority, your full name and date of birth, any reference or verification number, and the statement itself. We translate all of it, including stamps, signatures and verification instructions, so a case officer can check the certificate's authenticity.
If your certificate does record convictions, the translation is handled in exactly the same way: completely and accurately, with the original's wording preserved. Character decisions are made by INZ, and a licensed immigration adviser can help you understand how a record might affect your application.
