60 days... plus 30 day extension for 1900 Baht at an immigration office. That's 90. For the extra 30 days he needs a border run... And don't confuse months with days...
that's new to me... interesting. I am in Thailand at the moment for 86 days, entered on exempt on Oktober 1. So, before Nov 29, I have to go for 30 day extention. Would that mean I could teach in December?
