It's means if you enter Thailand you will get 60 days VISA exempt. You can then extend that by another 30 days (1900 baht) , so giving you 3 months in total ..if you want you can then leave Thailand to neighbouring country and then re- enter getting another 60 days exempt. I'm sure if I'm incorrect, I'll be corrected
cheers. I'm not a cheap Charlie unlike many keyboard warrior trolls on here. I don't need to carry on working, having retired from military and government organisations
