Maybe I'm confused... Is this person paying for a Vietnamese Entry Visa, or the DTV Visa at the Embassy or DTV online? Either way, I don't really care any further.
I paid for a four week cooking course and received a DTV in Vientiane back in September. Received it, entered Thailand, exited, and will re-enter after the holidays.
I did. Search my name and you can find the full post about my success. When I was looking for schools I found that most places aren't actual schools as their name would say they are.
