Any documents you submit to the USCIS or to the Embassy must be translated to English. However, you do not need a professional or “certified” translator. Anybody can do the translation and it can be hand written. The format of the translated documents does not need to match the original, although this may help the evaluator compare to the original document.
Translations never need to be notarized. Whoever does the translations just needs to sign and state that they are competent to translate the language to English and they certify that the translation is complete and correct.
