Would it be an issue in life? Mostly no, except at perhaps the worse possible time, as Heng, suggests. Is it hard to change? No. A quick trip to the district office to get a new ID card issued, and then the next passport the name will be updated.

She entered on her foreign passport, she should exit on it. If she's under 15, no stress, as their is no fine. You should always enter and exit thailand on the same passport. https://www.thaicitizenship.com/traveling-as-a-dual-citizen/

Curious to understand what makes you say that? A certified copy from SB of the RG seems to work pretty well. In any case, once you have an ID card, its never asked for again.

Females married to Thai husbands don't need to reserve a Thai name. https://www.thaicitizenship.com/thai-citizenship-based-on-marriage-to-a-thai-husband/

The best site for this is www.thaicitizenship.com - lots of free guidance there. Also a long running thread here (300+ pages).

Why on earth are you going for residency? If you are married to a Thai citizen then you can skip PR and get citizenship with roughly the same qualifications. Substantially cheaper (5000 baht vs 98,000 baht) and comes with a heck of a lot more rights.

You are misreading the law. This article explains how you are misreading those particular clauses in the nationality act https://www.thaicitizenship.com/thai-dual-citizenship/

Correct - that's the one. They should update their Thai ID when they arrive, and with that, head down to immigration and get an annual extension based on that. This article explains it all a little more: https://www.thaicitizenship.com/thai-ancestry-visas/

A child being born in Australia to two non-resident Thai parents wouldn't be eligible for citizenship there either. What's your point?

You didn't read far enough. There is a Q&A section down the bottom under the article and 'passport swaps' are addressed there.

As others as said, he won't be allowed to swap passports at land borders. https://www.thaicitizenship.com/traveling-as-a-dual-citizen/

Swapping passports at borders does not work. Repeat, does not work. Border guards on both sides look for stamp trails and don't like it if they are in separate passports. It only works in the air, so she'll need to fly down to KL, Singapore or Phnom Penh and fly back into Thailand on her Thai passport. As said, save yourself the heartburn and just front up the 1900 and get this visa. She just shows her ID card and she'll get this visa no worries. Next time she flies out she can do the passport swap.

If the mum and the child both entered on foreign passports they are both subject to Thai immigration rules. The mum will be fined for overstay despite the fact she is also a Thai citizen. Strange but true. The child also should get a visa, but will not be fined for overstay until the age of 15. Both of them can easily get this yearly extension of stay stamp in their swedish passport simply by showing proof of Thai citizenship. Next time, they should just enter on their Thai passport to save any fuss. https://www.thaicitizenship.com/thai-ancestry-visas/

Thai's born overseas go through life with two birth certificates. Their foreign one, and a Thai one issued by the Thai embassy in the country of their birth. It literally is a birth certificate (as opposed to what others have said here). It is just slightly different format to the ones issued in Thailand. You can read about it here. https://www.thaicitizenship.com/thai-citizenship-when-born-overseas/

If you can’t find your ID number for the district office to cross reference (it should be at the top of your Thai birth certificate), then you now have the option of a DNA test with close relatives to get citizenship https://www.thaicitizenship.com/thai-citizenship-using-dna-testing

This is Thailand's position on dual nationality. In essence, for those born dual citizens, Thailand doesn't care. https://www.thaicitizenship.com/thai-dual-citizenship/

If she's got an ID card etc, then no one will question her. An ID card is all that is needed to get her a bank account, social security etc and be paid just like any other Thai. Work permit and visas are separate departments. So for all intents and purposes she'll be treated as a Thai for everything except visa issues, so she'll be on the visa treadmill until she returns on a Thai passport and closes that loop. Strange but true.

she wont be able to 'close out' her visa as the previous poster suggested though it would be good if she could. If the enters Thailand on a foreign passport she'll be subject to the rules as they apply to that nationality. She'll have to leave and re-enter Thailand on her Thai passport. Fortunately, if she isn't planning on doing any imediate travel, she can get an extended one-year visa based off showing her Thai ID or showing she is the child of a Thai citizen https://www.thaicitizenship.com/thai-ancestry-visas/

No it doesn't. You're kids are fine. https://www.thaicitizenship.com/thai-dual-citizenship/

Start dropping hints that if they don't following the rules you'll forward the issue to the Administrative Court.

None of these cards denote Thai citizenship. They are simply ID cards for different categories of people. It may be that she was actually eligble for both. The Pink ID card is for migrant labourers from neighbouring countries. Anyone (not just companies) including Thai and foreign individuals can legally employ Burmese, Lao and Cambodian citizens on this. Typically they are used for domestic help, building and construction as well as factory and menial labour. All legit. All fairly straight forward to get with a legal sponsor and the help of an agent to navigate the process. The last 2 years generally and need to be renewed but the holder can work in Thailand, get healthcare and open bank accounts etc. The white card sounds like a card typically given to hill tribes or ethnic minorities, often with links to myanmar. They are quite restrictive, don't let you do much and normally don't let you move out of the district which issued them and normally don't let you work.

It is strange that they are asking for it. Maybe ask if they can waive it given it isn't a requirement? In any case, it is possible to do it from Thailand, however all that will happen is that they will liase with the Thai embassy in Finland. But at least you'll be here to to the Kor Ror 22. Not sure if that will require your father though to be present too. https://www.thaicitizenship.com/thai-citizenship-when-born-overseas/

Pre-covid Thai cars weren't able to enter at Poipet. The only two entry points were O'Smech/Chong Jom in the north and Trat way down south. The Northern one was the easiest paperwork wise (ie there was none) where as on the Cambodian side in Trat you had to pay per day you were there with your vehicle and they'd take you Thai export papers and return them to make you come back via that checkpoint. You can re-enter Thailand via any checkpoint however.

By the sounds of it, she won't be able to get her passport renewed if she is under 20. As others have said, she'll need to have a house registration, ID card and parents in attendance to do some or all of these things at that age. This is a good article floating around the internet. The second half in particular gives you an idea of that is needed to get registered in Thailand for Thai citizens born outside of Thailand. https://www.thaicitizenship.com/thai-citizenship-when-born-overseas/
