How often can I travel to Thailand and what are the rules for re-entry?

I can answer based on real experience. Prior to getting my long term visa I entered 8 or 9 times in one year. I left each time for work for 7-10 days and never needed and extension.

Does anyone know if Vietnam and/or Cambodia is similar? I'm coming from Costa Rica where you had a six month stamp and you could border cross for infinity.

**** In theory, no limit. In practice, immigration officer will check your passport for abuse of the system and likely refuse entry at some point. After how many? Who knows, luck of the draw.

**** “How long can I stay in TH on visa-exempt entries?" is like asking "how long is a piece of string?"

NOW read it HERE - the classic reply of Tod Daniels to the never ending question “how often can I enter Thailand”:

“You can keep doing it until you can't.

After the first 1-2, it becomes a gamble. It all depends on which IO you're dealing with. Some people have been ok on just visa-exempt entries (and extensions of said stamps) for periods of over 6 months or even a year.

However, in the past year or so they've really been cracking down on people with back-to-back tourist visas & visa exempt entry stamps. Especially those with long ago Covid extensions.

We RARELY let posts prevail, where people ask if they're going to have a problem getting in get posted on this group and we get a LOT of people wanting to post questions like that.

It's not that we deny those posts because we don't want to answer/help you, the reason we don't let them on is because there are WAY too many variables in that answer and truth be told there is NO real correct answer.

Things that factor in to you entering Thailand successfully are

-previous entry / stay history

-what airport you fly into

-whether you were here over Covid

-whether you have an old ED or Volunteer visa in your passport

Unfortunately the real deciding factor is the officer you're standing in front of when you go to stamp in - and that is beyond your control.

There is NO rhyme or reason on why some people with extensive entry stay histories skate in and other people are pulled aside and grilled after one entry

There doesn't appear to be any specific nationality they're targeting, no number of days in Thailand, no previous number of entries, although ED and Volunteer visa. Especially those b/s back door ones people got during Covid and those Covid extension stamps are considered "stamps of death"

When flying in with extensive entry/stay history airport choice DOES seem to factor in to it. BOTH Suvarnabhumi (BKK) and Don Mueang (DMK) seem much harder on people than say Phuket or Chiang Mai (which has no reported denial of entries)

All you can really do is be prepared by having

*** proof of funds (20K baht or the equivalent in CASH)

*** proof of onward travel within the number of days you will get stamped in for - that means if you're comin' in free stamp for 30 days have onward travel IN 30 days (because that "I've got onward travel in 60 days because i going to get a 30 day entension" line doesn't always work

*** proof of lodging for the time you're here (at least for a week)

They (officers at passport control) CAN ask for any of those things, all of those things OR none of them. Please remember the fact you were never asked does NOT mean those are requirements to enter, nor does it mean no one is asked, it just means you weren't asked

Also remember the fact you have a tourist visa doesn't guarantee you get in (especially with an extensive entry/stay history) all having a tourist visa guarantees is IF you get in, they stamp you in for 60 days.

A new passport doesn't "wipe the slate", your entire entry/extension/stay history is available to every officer at every entry point to Thailand with a click of a button.. Now it can help for them just paging thru the passport but IF they wanna really see how much you've been coming here, a new passport isn't gonna help that much.

There are more than a few 'fast track' or 'safe entry' services out there (and I believe the company that owns this group even offers it)

Make sure whoever you contact about it, knows your WHOLE entry/stay history. Fudging your history to a company that's gonna help you get in is not a good idea. That's about people. Just wanted you to know why we don't let those "will I get in okay" posts on this group very often (if at all).

As long as a piece of string. What visa are you on. What passport. How many times have you been in and out etc. Give us a few facts please.

They set the rules play by their game. I've been here 28 years shortest I've left Thailand and returned with 2 minutes

There is no legal requirement to be out of Thailand for any amount of time. And if you have a long-term visa and you can meet the requirements for extensions, you never have to leave.

If you are asking about short term tourist stays, then you can do it until you can't. Each entry is at the discretion of the immigration officer you are standing in front of, and after a certain amount of time they will consider that you are abusing the system. You cannot live in Thailand long-term without a long-term visa.
