Hi. I think I understand this portion of the Fiance Visa instructions application but I just wanted to ask to make certain. In the translation instructions it states the following:

"All documents neither in English nor in Portuguese must be accompanied by certified English translations done by a Sworn Public Translator."
The translation must include a statement signed by the translator that states that the:
• Translation is accurate, and
• Translator is competent to translate.

Does this mean that translations are only required for languages other than English or Portuguese? For example if our emails were in Chinese then we would need to get the translations to either English or Portuguese? But since our emails are in either Portuguese or English then we will NOT need to translate all the Portuguese emails to English. Is this correct? Thanks.

No, you do not. In Brazil, translations are only required for languages other than English or Portuguese.

You're correct (as long as you're talking about the interview stage).

You don't need a translation for the consulate, and most likely they won't even look at them. It's good to arrive with a nice big organized folder of proof though, shows you care and just in case you do have plenty of proof with you.
