Burak Kurt I've not done a DTV. If you already have the visa you are allowed multiple entries....maxumum stay of 180 days? So that would require just keavu g and returning to re-activate your visa. As I understand it, if you hold a DTV, you can leave and re-enter Thailand as many times as you want without having to apply for a re-entry permit.
If you haven't got a DTV yet, the best way is to get one online - it requires proof of funds. - at least 500,000 Thai Baht
Ok..if you need a visa, then you must go to the consulate or Embassy that issues them. E.g Laos, Vientiane or Savannakhet. Or Cambodia or Penang or even Singapore.
Otherwise just pick a border, stay in the other place overnight and come back
Don't forget it isn't a race, you can take your time ymto visit the other country
When did you read that? You need to supply a reference for that....
Thaiger are not very reliable - but the ETA was scheduled for June 2025, but then with the implementation of TDAC, this seems to have been put back. It's bad enough the Thai authorities implementing one digital system but to do two simultaneously seems rather foolhardy!
