Hey Joe, I am having exactly the same situation as you. Dates are the same. The agency said ''Given your visa expiry on the 25th, what we usually recommend in cases like this is to re-enter Thailand using a visa exemption, which is a valid reason for leaving the country. Once your DTV is approved, you can either wait inside the country until your visa exemption is over or exit and re-enter again using the DTV visa.'' Important part is ''if you plan to leave, we would recommend you to take a picture of all pages of your passport.'' I hope it helps
