Yes, we require English translations for all documents issued in a language other than English.
Please do not submit original/certified translations since they will not be returned to you. Please submit complete, legible copies. You may prepare the translations yourself, as long as they are complete, literal, word-for-word, and in the same format as the original document.
If the content of the document matches the content of a document in your possession, then you can prepare the translation based on the document in your possession. If you do not know the content of the document in the sealed envelope, then you should request two sets of sealed envelopes from your institution, so you can open one set to be translated.
