Can I fly to Thailand while my DTV visa application is still pending?

The consensus among commenters is that you should not fly to Thailand while your DTV visa application is pending. Entering Thailand before receiving approval could lead to the cancellation of your application, as it typically requires you to remain in the jurisdiction of the consulate that is processing your application. Most embassies take more than two weeks for processing, and leaving your country could jeopardize your application and result in losing both your visa fee and your application.
