The extention is giving the same day while you wait as long as you you have all the docs Ready. After you got the Extention the same day you can apply for a re-entry which you will also get it while you wait ....and then you can leave the country when you want
I think you should get 30 days extension... Payaho is not far from Chiang mai.. Why don't u go there... By bus maybe 2h.... I am sure you will get it there... Good luck and congrats for yr baby
Is actually very easy just go to the DLT get a form... One part the seller has to fill it in with the photicopy of his Id and photocopy of his Tabien
baan then the buyer can fill in his part... Photocopy of his/her passport where the picture is and the last entry stamp to Thailand... Then just go to the DLT alone (no need the seller).. They will process it fast.. Cost around 200bt....no need an agent or anybody.. Very easy to do it 🙂
