What about documents issued in a third language such as Chinese or Japanese?
Use a translator credentialed in that exact language pair. Avoid relay translation through Thai or English — layered translation degrades accuracy and agencies may reject it.
In-depth Answer
Many applicants hold a multi-country file: a Japanese employment reference, a Chinese marriage certificate, a Thai birth certificate.
The rule is that each item is translated from its source language into English by a translator credentialed in that pair — not Chinese into Thai and then Thai into English.
Every relay step adds drift, especially in proper nouns, figures and legal terms, and agencies want a direct line between original and translation.
When assembling a multilingual bundle, include an index noting who translated each item, from which language, and on what date.
Officers verify faster and ask fewer questions, which matters most in skilled visa cases with work history across several countries.
