# You don't necessarily have to use to professional translator. However, the translation must be accurate. If there appears to be errors in translation (e.g., because there are so many English misspellings, sentences do not make sense), you may be required to send your documents to a translation service.
# If the document is being submitted in the U.S. (for example, to USCIS), the translation does not have to be notarized. If the document is being submitted outside the U.S. (for example, to the Embassy or Consulate) , it must be notarized.
