I’m a US citizen. I believe we have 45 days allowed to visit on passport (it could be 30 days, I have read both). I just had a visa for 60 days which ran out. I’m currently visiting Cambodia. I would like to return to Thailand but I don’t know any of the rules. Can I return after my 30 day trip to Cambodia? And what is the best way to do this? Passport or another Visa? And if I want to stay longer, I see people on here writing about extending their visa (is this a tourist visa?). And what if I marry a Thai woman (currently have girlfriend there)? Can someone please enlighten me? Thank you

TLDR : Answer Summary
As a US citizen who has been in Thailand and is now visiting Cambodia, you can return to Thailand with a visa-free entry allowing for either a 30-day or 45-day stay depending on when you enter. You can extend your stay at a local immigration office, with the possibility of a one-time extension of 30 days. If you wish to stay longer or are considering marrying a Thai citizen, you may want to explore specific visa options that cater to those scenarios.

If you enter Thailand before April 1st without a visa you will receive a 45 day stamp. You can extend this one time for 30 days at the local immigration office.

If you enter on April 1st or later, then you'll receive a 30 day stamp which you can extend one time for 30 days.

 I have a question I’m hoping you can help me with. I noticed on site people writing about being denied airline boarding and/or Thailand entry without return ticket. If I’m using passport entry for 45 days, and intend to extend 30 days why would I buy a return ticket if I don’t know the return date yet? I’m assuming that extension needs to be approved, but can be denied. Also, if I buy a return ticket to reflect 45 days it’s a waste of money if extension is approved (as would be a return ticket projected out 75 days if extension denied). Please advise. Thank you.

 because the law says you must be able to show proof of leaving Thailand within the days you'll be stamped in for. Extensions are not guaranteed.

Immigration rarely asks only if they're looking for a reason to deny entry.

Much more often airlines require you to show the proof sinde they can get in trouble if you're denied entry.

 I’m not suggesting that you’re suggesting anything but I feel you might be saying it’s a good idea to have a return ticket corresponding with the 45 day and count the loss (price of ticket) if/when I get an extension? Is this what most people do?

 Google "onward travel ticket" and you can get proof of flight out of Thailand for $10-$15.

 you have been very helpful. I really appreciate it. Questions keep popping up. When I return to Thailand on the 45 day passport, when is it reasonable to apply for the extension?

 most offices allow you to apply when you have 30 days left on your stamp. Some bigger offices like Bangkok, Chiang Mai and Phuket allow you to apply when you have 45 days left, so if there you can go right away.

A couple of offices (Koh Samui, Jomtien) want you to come in when you're on the last week of your stay.

 I knew more questions would arise. I’m flying into DM airport Bangkok. Is the immigration service center the place I go to? Do I need anything besides my passport? And what kind of reason/justification do I give? (Thinking about retiring there, etc?) thanks for your help

 are you asking about your extension? I'm not quite sure what you're asking about because you mention your airport which has nothing to do with an extension.

 it doesn't matter where you fly into, it matters where you're staying. If you're staying in Bangkok then you'd go to IT Square Laksi for an extension of visa exempt.

 Irrespective, you're giving out incorrect information by saying a decision hasn't been made yet, but it has. The 45 day concession ends on March 31. That decision has been made and it is what it is

 apparently the Tourist Dept has asked for it to be extended until the end of the year.

 That was the TAT. They don't have much influence over the Royal Thai Police who don't want it extended. The point I was making is that at this stage it finishes on March 31, and there's been no further reports of any extension, so any advice must be based on what is known, not what is rumour

 you can enter Thailand using visa exempt at a land border 2 times per calendar year. There is no official limit by air. After 2-3 times you'll likely start being pulled aside at passport control and asked a lot of questions about what you're doing in Thailand and why you're trying to live here on a tourist visa. Eventually you'll be denied entry and sent packing.

 where did you hear or read that the 45 day exemption will change in 30 days after the 1st of April? Nothing decided yet and rumours say the 45 day will be extended until the end of the year.

 the law that temporarily increased it to 45 days ends March 31st. Therefore it will go back to 30 days. We don't give advice based on newspaper articles about proposals.

 I'm telling the reality. The law ends on March 31st. As of today, it will revert to 30 days on April 1st. That is a FACT. It's much better to have people prepared for that than for them to make plans based on something that likely will not happen.
