Again, Phuket Sandbox rules only apply to international arrivals to Phuket. Domestic arrivals in Phuket do not have to play by Phuket Sandbox rules. It's really that simple.

// U.S. nationals, including dual nationals, must use a U.S. passport to enter and leave the United States. Dual nationals may also be required by the foreign country to use its passport to enter and leave that country. Use of the foreign passport to travel to or from a country other than the United States is not inconsistent with U.S. law.

Yes, Canada allows dual citizenship.

Highly recommend this fantastic website for anyone who wishes to become a Thai citizen:



I would point out that if you're married to a Thai you should really seek Thai citizenship rather than permanent residence as it's actually cheaper. The only reason not to go for Thai citizenship is if your current citizenship country does not allow dual citizenship.

Well, my curiosity was piqued enough to look it up....

He was never a US citizen only because he was a child of a foreign sovereign, which is a loophole in the US law. A good thing too otherwise he would have been an "accidental American" and subject to American taxation, which would most definitely not have been a good deal for him. ;-)

The late great king Bhumibol was born in Cambridge, Massachusetts where his father was going to Harvard to study public health administration. As someone born on US soil he was entitled to claim US citizenship (he is the only monarch to ever have been born in the US). It's not clear to me if he ever pursued his right to US citizenship. I just don't know that part of the story. He could very well have had a US passport, I just don't know.

Yes, name changes are a good reason to show if necessary.

What I'm trying to avoid is the person with multiple passports and they hand the poor immigration officer both and stand back and think he/she will figure it out. ;-) And they will... eventually... figure it out. But if you are smart enough to have two passports you ought to be smart enough to figure out which passport to give and keep the other out of sight. Better for you, better for them, better for the 100 people in line behind you. ;-) Yes, if you have a name change issue that's different and you do what you have to do.

Thanks!

Like all Thai laws, it's written in Thai and it may not even be well or unambiguously written in Thai. And then it gets translated to English and confusion reigns. Thais ARE allowed to have dual citizenship. People who believe they are not are misreading/misunderstanding the Thai law as it presently is.

@Danny ******

I don't believe it can be automatic, but welcome anyone correcting me if I'm wrong.

No! No you don't. You are misunderstanding the situation. They do not HAVE to choose! They can choose if they WANT to. If they don't want to they don't have to. They can remain dual nationals, past 18, the age doesn't matter. Thailand accepts the existence of dual nationals. If you don't believe me, fine, seek the advice of someone you trust, but don't act on bad information. Talk to Thais who are dual nationals. They weren't made to choose, at 18 or any other age. Please investigate further. What a terrible waste to throw such a positive thing away unnecessarily.
