During the process of working with Phuoc & Associates, is it possible to have written communication with me in two languages (bilingual) at the same time (for instance Vietnamese and English)?

Languages used in our main communication are Vietnamese and English, or another language in some special cases (including French and Japanese). However, in the documents exchanged between us and clients through email/fax/mail, we will only use one of the languages ​​as mentioned above. We will write in one or more languages​ ​should a client request, provided that an additional fee will be charged for our translation services.
