Applications from outside of Belgium or Luxembourg as well as any pending visa applications from foreign nationals who are currently in Thailand will be automatically denied.
Thank You Very Much for you lr report on your experience with getting a DTV E–Visa at the Thai Embassy in Phnom Penh (Cambodia)
No excuses for the consular/visa staff processing Thai E–Visa applications at the Thai Embassy in Phnom Penh, but they have more pressing issues to deal with nowadays, and, fortunately for many, there are other Thai Embassies/Thai Consulates to choose from to apply for a DTV E–Visa or any other type of Thai E–Visa within the immediate region with faster DTV E–Visa processing times
No, and since you already exited out of Thailand and will make a new entry into Thailand again, a new TM.30 should be filed regardless, as this is a new entry into Thailand and the new TM.30 would reflect where you are staying now
