You can START the application, make a profile, log in to the eVisa online system, upload all the documentation required and then SAVE that application without applying until you exit thailand
Are you physically going back TO your home country to apply for the DTV <- because you have to be IN the country of the thai consulate you're using for the application.
Unless you're going back to your country, just go to a nearby country and apply thru a thai consulate once you're there and can upload the visa/entry stamp showing you're legally allowed to be IN that country (that's all they require as far as "residence"
NO!! you have to physically be IN the country of the thai consulate you're applying for the visa thru 🙁
So if you're leaving thailand you have to stamp IN to Malaysia then you could apply at one of the consulates in Malaysia based on where you are in that country (what port you dock at)
This is the pop up on the eVisa website about what consulate serves what area in Malaysia
they can't 🙁 Immigrations inside thailand can't cancel VISAS, 😮 they can cancel extensions only
The visa the O/P holds is a 6 month METV that they got from a thai consulate in their country before they came here. There is no way to cancel it. They wait it out and apply for a DTV once the METV itself expires
