Should my daughter get a working visa for Thailand?
What she is doing is illegal. Even for voluntary work you still need the appropriate visa. Also now the visa rules have changed and doing a border run will only give her 15 days not 30 like in the past unless you arrive by air than you get 30 days. This being said, I know many agencies here that have people on tourist visas working for them doing such things as English Camps and teaching. It’s illegal but it is done everyday here. The choice is her to make. These agencies don’t care a bit. If caught by the police she will be turn over to immigrations police and she could be held for a few days at a immigration jail and then deported. This is rare but it has and could happen.
