Do you have to pay the visa application fee again if your application is declined in Thailand?

When a visa application to Thailand is declined, the application fee is non-refundable, meaning you will have to pay the fee again for a new application. This is confirmed by multiple comments stating that if the application is not successful, you will lose the fees already paid. Additionally, while clarification or additional documents may be requested during the same application, a decline requires a complete resubmission.
