ORIGINAL POSTER
I’ve been married to a Thai girl for 40+ years. We have travelled back and forth between Thailand and the USA for vacations and to see family. My wife has always gone to Thailand on her USA passport ( she also has a Thai passport). What happens if she travels on her USA passport to Thailand ( visa on arrival ) and then decides to stay for 6-12 months. What happens when she decides to fly back to the USA at Thai airport passport control?

TLDR : Answer Summary
A Thai citizen with dual citizenship (US and Thai) traveling to Thailand on her US passport may face complications if she intends to stay for 6-12 months without the correct visa. It has been advised that she should ideally enter and exit Thailand using her Thai passport, as this avoids issues with overstaying and complicated visa requirements. Recent changes in Thailand's immigration policies suggest that dual citizens can enter on any passport as long as they possess identification confirming their Thai citizenship. If she enters Thailand on her US passport, she may be treated as a foreign national and could incur fines for overstaying unless the correct visa or extension is applied for.

NOT 'visa on arrival', it's a 'visa exemption' - totally different animals.

On a Voa (which she isn't eligible for anyway and would have to pay for) she's get 15 days, but a visa exemption (which she is eligible for) would give her 30 days free and then can be extended for a further 30 days fr 1,900 baht.

If you've been travelling between Thailand and the US for so many years, I am astonished you don't seem to know the rules yet.

Leave US on US passport only. Enter Thailand with Thai passport. Leave Thailand on thai passport. Re enter US on US passport. Easy peasy. Stay as long as you’d like. Don’t fuck around and find out by mucking with immigration even if a thai. They don’t appreciate it even when Thais pull that. shit.

 because returning to the US, or many other countries, requires a lengthy visa application process if using a Thai passport, and when entering another country your passport must show that you left a country legally, shown by the exit stamp.

 just don’t change passports when transitioning out/in or out of same country. You certainly can change passports to your county of citizenship. If you have two. Use two. Yes, you have to follow all laws regarding said country as well but you most certainly benefit from having two passports and citizenship when travel between thuja two countries. Every country is different. So enter and leave on the passport that benefits you the most. Duh 🙄

 must show? Most countries, including the US, do not give you an exit stamp. I doubt that countries care about exit stamps of other countries.

If she has entered with her Thai passport before, they have her fingerprints on record. When she tries to enter with her US passport they might flag her fingerprints on file with the Thai passport and question her at that time. Its anyone's guess how they handle her case from there.

As of three weeks ago it no longer matters. As long as she has her Thai ID card, or Thai passport, for ID perposes she can enter on any passport, and will be treated as a Thai citizen, going through the Thai citizen line at immigration using her US passport, and have no concerns what-so-ever about overstay. She is Thai, she can't overstay anymore because she used her dual citizenship passport. This went into effect about three weeks ago. She can enter and exit on her US passport, and as long as she has her Thai identification she is treated as a Thai, with no overstay concerns.

She should be carrying both passports. Enter on Thai. Leave on Thai. Enter US on US. Leave on US. If any immigration officer asks, she only has to tell them she’s a dual citizen and traveling between her countries of citizenship.

 Time was, this is how immigration workers in the US behaved, also. I have many dual citizens in my family and they say, 1) don’t flaunt the fact that you have 2 passports. 2) Enter each country with the appropriate passport. Then there are no stamps involved.

 I appreciate your kind words. I wanted to emphasize that asking for or giving advice can often be more constructive than just giving a personal opinion. While everyone is entitled to their own point of view, advice tends to be more helpful, don't you think? I may have reacted violently in your situation, which I must admit was inappropriate. I hope that this doesn't seem too politically charged and now stamps me as a politician 😄. I wish you a pleasant evening and thank you for your time!

 Perhaps you could keep your sincere questions to yourself as they don't seem to have any value to the question. It's important to remember that everyone has different priorities in life and everyone needs advice at some point. This site is probably more about helping people than making fun of others, after all there are many other sites for that.

They're changing how they treat Thai citizens who enter Thailand on a foreign passport now. So they will be seen as Thai rather than foreign nationals by immigration.

What that actually means, who knows as it's a recent change. Maybe no need for extensions or fines? But you can also just get a 12month extension at immigration for 1900B, just by proving her Thai citizenship (ID card, Passport etc.)

I guess my first question is why would she even consider it? A Thai citizen can enter Thailand even on an expired passport. Why go through the trouble? If she enters with her US passport she is going to have to get in the normal line (not the Thai citizen line) and wait like everyone else, and then once she gets into Thailand she will be considered American for immigration purposes and will need to go to immigration and apply for the 1 year "Thai citizen" extension.

Why would anything happen when leaving at passport control? When you enter a country you show a passport. You show the same passport when you exit that country.
