[Question] Need help with authenticating a certificate.

Community Novice

Good day, I have completed a TEYL course and obtained a certificate. I need to have it authenticated to be used for work permit here in Vietnam. Do you have the steps on how this can be done? I heard it needs to be sent to the embassy (not sure if Canvas is a US-based company) and have it authenticated there. Any idea will be greatly appreciated. 

Thank you.
