The rules may change in the future, but for those who have already acquired the visa, it’s a five-year multiple-entry visa. The rules cannot be changed for them; they are grandfathered in. If any new requirements arise for the visa extension while at immigration, a quick trip across the border will eliminate those requirements cause it’s a multiple entry for 5 years. What these people already paid the money for.
I don't know who wrote it, but it's completely accurate. Each embassy will have its own guidelines for obtaining the visa, but once you have it, no additional documentation is required for the next five years.
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.
once you get the visa, only proof is the 500,000 baht at the bank and that proof is only on the extension of stay for additional 180 days. Leaving and going during the five years, it’s a one time requirement on the 500k.
I’m amazed after two years of this. People still think an AtK is as accurate as a PCR and when the ATK is negative and PCR is positive, they feel something is wrong.
