2026 saw major changes to Thailand visa rules
When I first moved here there was a whole mess of people that were just one whatever visa and stayed here for a very long time. Prior to me moving here there are loads of stories about people that would make "visa runs" to a nearby border every 30 days and they would do this for sometimes years. Nobody had a problem with it back then either and I have been told that they wouldn't so much as receive a nasty look from the Immigration official at the land crossing.
When I moved here visa runs were already mostly on the way out with only a few agents offering such a service and they would seriously look over your passport to see if you were likely to be turned back before they would even book you on the bus. Prior to that time this minivan would leave every day, sometimes multiple busses per day.
Those days of simplicity are behind us and at the end of last month the Thai government went even further with their visa changes to make it even more difficult for people to stay in this country for more than just a few weeks in a row.

Before I go on I want people to know that I love living in this country and I have a work visa and work-permit, so these changes do not affect my life at all. The only reason why I bring it up is because at the moment this country is suffering greatly as more and more tourists are deciding to visit other SE Asian countries and almost all of the surrounding countries are seeing a rise in tourism. Thailand on the other hand, lost its number 1 spot for the first time since they started recording these things in 2025 and is slated to be one of the only countries failing to grow tourism.
Since this country's GDP depends on tourism nearly 20%, this kind of seems like a bad time to place more restrictions on visas, don't you think?
Prior to the end of June, there were 93 countries that were eligible for 60 day visas, nearly all of those countries have been reduced to 30 days and some of them have been even further reduced to a mere 15 days.
Prior to the end of June, there were 34 countries that were eligible for VOA (visa on arrival), now there are only 4. Keep in mind that there is a lot of countries that are, and always were, eligible for travel into Thailand without a visa and one is simply given to you at the airport. If you are from a relatively wealthy country like the United States, you don't need to get worried about getting turned away at the airport because that isn't going to happen. However, your stamp will only be for a maximum of 30 days.
In the past you could simply decide to stay longer if you felt like it by getting another visa at a border crossing or in some situations, by just going to an Immigration building, but while this is a very grey area there are talks about cutting down on this is limiting the availability of visa extensions back-to-back to only 2 times per calendar year.
The much ballyhooed Destination Thailand Visa (DTV) that was launched to allure digital nomads back to Thailand has already proven a real mess and now it is limited to 180 days per entry, and there are talks of making this non-extendable in the same calendar year. Why? nobody knows. It hasn't happened yet but if there is one thing that I know the Thai government seems to just love doing, it is to fiddle with something until it no longer works at all.
Retirement visas are still available but the rules change so much that if you don't hire an agent to sort it out for you, well, good luck! While in the past Thailand was very welcoming to retirees looking to spend their pensions in Thailand there are loads of stories about old folks getting pissed off at the amount of accusations and red tape and just uproot their investment and move on to another country. This has been a staple of the That economy for decades and to screw with this relatively affluent and extremely crime-free segment of society is something that makes ZERO sense to me. While the official rule is that you have to put 800,000 THB into a savings account it seems that this "rule" is changed depending on the location of where you apply as well as the mood of the immigration official that happens to be working that day.
To make matters even more fun a Digital Arrival Card is required for everyone entering. The airlines do a good job of letting everyone know that they MUST have this before coming to Thailand but you wouldn't believe the line of really pissed off people at the airports that somehow managed to make it to the country without being made aware of the necessity of this form. It only takes a few minutes and it is just standard information but what gets me about this is that it is just a digitized version of the old paper card that would just get thrown into a bin behind the official right after they took it from you. You can't tell me that this information is actually being used for anything let along verified by the person in the glass box.

These were such a pain in the butt back in the day because apparently you would be in deep trouble if you lost your half of this which was your "departure card." I would love to know if any of this information gets used at all. To me it just seems like some people with ties on in an office laughing at all the hoops they can make commoners jump through.
If you are just coming here for a short holiday don't worry, none of this will be something you will probably even notice. The problem is that for a very long time, Thailand has been seen as an affordable place for people to go and live in for a few months without any hassle. The government seems to be pretty dead-set on making it a hassle.
