I believe it's a mistake to try to get the DTV Visa in Laos for language study.
Only one report of DTV success for language, as reported by a member in reply to your post, and that was from the Sydney Australia Thai Consulate.
Why have you chosen Laos for a DTV in language study? Did some school suggest that? And if they did, what success have they had with their students approved for the DTV Visa?
What is your passport nation?
Have you been in Thailand for several years working under the radar or with a Thai work permit?
Have you already had an Ed Visa for language study in your Thai Immigration history?
Suggest you look at another reason to obtain the DTV visa.
Muay Thai training school
Thai cooking course... or..
Suggest you review this option...
With reported success in getting it issued by the Thai Embassy in Phnom Penh... course fee is 9,995 Thai baht for 5 years of monthly classes or sessions.
