Application fees: Online DTV application VS in Person at Consulate/Embassy

I am seeking clarification on the application process for the DTV visa. Specifically, I would like to inquire whether submitting my application in person at the consulate would be a more secure option compared to applying online.

My concern stems from the non-refundable visa application fee of 10,000 THB. I recently came across a video featuring an influencer who claimed that they were only required to pay the application fee after their application had been approved.

In contrast, I understand that online applications require payment of the visa application fee at the time of document submission. Could you please confirm whether my understanding of this process is accurate?

Thank you for your assistance in
