When it comes to official business, one person gets trained for a position, and then they work there for the rest of their life in most cases.
The verification and certification process is called notarization.More often than not, people only require a certified translation of their documents.
For many years now, immigration authorities only ask for this type of translation.
It is considered enough to verify the authenticity of a paper.
However, in certain cases, another type of certification is required.
In the former type, a translator states on a piece of paper that their work is accurate and then sign it.
