Hello, quick question, I am planning to submit my application for DTV in Hanoi, for remote work.

Regarding the documents required to prove ongoing relationship with clients (contract with client, letter from client saying that you can work from thailand, etc.) do these documents need to be written in English, or can I provide original documents and letters in my native language (since my client is located in France), along with a translation made by myself ?

Thanks for any advices :)
