Hi everyone, what is the difference between authentication, legalizing, and notarizing when it comes to US Diplomas and transcripts for a non B visa to teach?

My plan is to have my Bachelor's degree and transcripts legalized at the US consulate here in Hong Kong, and then authenticated/legalized at the Thai consulate after. Is this correct, or do I need to notarize also?

Many thanks!

I need to send my NYC issued diploma back to the States for Authentication by the Thai embassy or consulate there. Which is the most dependable service for such a task? It's my understanding that it must first be notarized by a notary in the state of New York. After that, will I also have to send it to the US department of State for their authentication before sending it to the Thai embassy for the final step?

Does anyone know how we are suppposed to get official documents like birth certificates and marriage certificates from the US notarized. The US embassy in Chiang Mai and in Bangkok doesn’t do it anymore, yet it’s still required for family members following on my work visa?
