TESOL

Hi.

Just need to know if someone can help me re my TESOL certificate notatization. I got my certificate from online and i need it notatized. I only have the PDF copy, they said the hard copy will be mailed but i have to have it notarized already. Can the PDF copy that i have notarized or do i have to wait for the original copy from the US? Should it be notarized with US Embassy first before translation to vietnamese? Thanks

Who is asking for it to be notarized?
