this is no official website, and it is wrong. I posted an actual picture of the official Thai Customs, why do you bring up an advertorial website? . . . . why would you believe in a bogus website that tries to fool you by calling itself website.go.th ? This website was NOT created by the Thai government
I already asked Tod Daniels 3years ago. There is no such rule since 2 years, when the embassy websites stopped to text it. . . . . . . BUT BEWARE! You will need to take this with a pinch of salt. There WILL for sure be the moment when an Immigration officer will deny a visa-exempt entry or the 30 days extension, if your passport is lined with these stamps. If you think you can do this over and over again, you will definitely fail. There is NO "unlimited" number of visa-exempt entries any more
Regarding the provision of “90 days within 6 months for visa exempt entry” on embassy websites
In fact, no one at the Thai Immigration knows of such a provision
On the contrary, the immigration website even states that you can make unlimited visa-free entries by air.
And I know of only few reports of anyone not being approved for a 30-day extension of a second consecutive visa-free entry.
Three years ago I informed the “Thai Visa Advice” group about this ominous "90 days in 180 days" rule.
It used to be written down on the website of the Thai Embassy London, UK. About two years ago, the text vanished.
So the claim that this rule was abandoned 15 years ago is DEFINITELY wrong.
The information obtained from the “visa guru” of the group was, that immigration is not complying at all. There is NO immigration “police order” that states that you can enter Thailand on a visa-exempt basis and not be in Thailand for more than 90 days within a 180-day period
What the embassies write often does not correspond to the immigration process. The two belong to different ministries and are subject to different rules.
But BEWARE! The times of consecutive limitless “visa exempt entries” are definitely over.
In any case, you can make two visa-free entries per calendar year by land and unlimited entries by air.
This might include two 30 day extensions. It is however up to an officer’s discretion.
One thing to keep in mind is that beginning with your third consecutive visa-free entry, or your second or third application to another 30 days extension, you have to be prepared to be taken aside and asked about the purpose of your trip.
Then you should have the THREE famous proofs:
*** 20,000 THB in cash (can also be in another currency)
*** proof of accommodation for the next few nights, and
*** proof of onward travel out of Thailand within the expected stamped length of stay for visa-free entry
know. You say that there is no rule on how many times you can enter visa-exempt and receive a 30 days extension? Just visit the website of the Royal Thai Embassy London. Here on the page concerning the "visa-exempt entry", you can read the following. Well, the embassies don't make up the rules, rather Immigration does make up the rules. However, contrary to your bar-stool science, the rule is CLEARLY written on an official Thai government website!
