Just as the ocean shifts from stormy to calm, so does the landscape of immigration. At the moment, they've made it extremely easy. Can it change later? Of course, just like the ocean does. However, if you have the five-year visa, they can't cancel it. You're secure for five years. Right now, the requirements are as easy as just one doctor's appointment or a ticket to a music festival, along with 500,000 baht. These are the easiest rules I've seen in my 25 years here.
