Thanks so much for this info. Its very valuable for all of us. However, I am not quite sure I understand this sentence:
"The applicant, if on their SECOND TOURIST EXTENSION, and UNABLE TO GET THE CONSULATE LETTER, must FIRST apply for the 7-day emergency extension (1900 THB) ........ and then, with the ORIGINAL COPY of their consulate letter, can apply for 30-day extension at the tent"
How can applicants unable to get consulate letter use original copy of their consulate letter?
