How can I get US birth and marriage certificates notarized for my work visa in Thailand?

The US embassy in Thailand no longer notarizes documents such as birth and marriage certificates, which are required for visa processes. To obtain notarization, it's suggested to have the documents certified in the US. For documents already in Thailand, they need to be translated into Thai and certified by the Ministry of Foreign Affairs. In some cases, individuals have had success notarizing an affidavit that confirms the authenticity of the documents, followed by translation and authentication at a Thai consulate.
