When filing visa applications in the United States, one sometime needs to provide certified translations of official documents from the country of birth. Is there any online resources that would give translation templates or examples for French official documents such as birth certificate, diplomas, or transcriptsm into English?
There are plenty. I used REV, but there are countless other similar services.
That said, "certified" means the translator certifies that he/she knows both languages well enough to translate, and that's it. Rarely you'd need an official or notarized translation in the US. So if you have a friend who's fluent in French and English - they can do the translation for you, and certify that they know the languages well enough. Here's a USCIS example for a certification.
