Hi mat2k! Please specify your document type.
Are you regarding to:
1) your reference letters
2) proof of employment
3) application
4) Educational certification
?
1)Your reference letter, you do not have to prepare it.
2)Your proof of employment, I gave them in Japanese. They just simply
wanted me to jot it down saying "proof of employment" and that was it.
3)Application, you must have it in English.
4)As in educational certification, you do have to have it officially translated in English.
I hope this helps.
