Any qualification or document that is not originally in English or Welsh will need a translation to requirements set by the UK Border Agency (UKBA).
The UKBA requires a fully-certified original translation for each document you provide that is not in English or Welsh. The translation must:
be made by a professional translator or translation company
include details of the translator or translation company credentials
include confirmation from the translator that it is an accurate translation of the original document
include the translator/translation company’s contact details
include the date
include the translator’s original signature and full name or the signature and full name of an authorised official of the translation company
If your translation does not meet all the requirements, even if it is just one point, then you must have a new translation made. Your visa application can be refused if the translation does not meet the requirements.
Using a translation provided by your school or university
Your school or university may have given you a translation of your qualifications. To use it for your visa application, it must meet the requirements above. Otherwise, you will need to have another translation made.
