Translators specialize in specific languages. Most translators are native speakers. However, this is not a requirement to be a translator. Official translation refers to a translator who is certified in the language or languages they translate. Hiring an official translator allows for a natural flow with conversations. When you think about it, most people do not talk in proper sentences during a conversation. Being able to translate back and forth in a conversational tone often results in a more productive exchange. On top of that, an official or professional translator is likely to know local dialects and other nuances that help improve communication efforts.
