Can anyone recommend a legal firm or agent for complex immigration questions in Thailand or Los Angeles?

@Richard *******

contact the Thai consulate in LA. They deal with this enough to know what she needs to do. Does she still have her expired Thai ID, and passport?

@Richard *******

when you get to Thailand if she can produce a copy of the house book she was listed in that will be a big help. At the extreme she might need a DNA test, and be able to compare that test with a Thai relative's DNA test to prove birthright. It helps if she knows which province she was born in, and can get a copy of her birth certificate. Even though her Thai passport is expired, she will still be let in as a Thai, and go through the process of getting her new Thai ID card. It could be simple, based on her expired passport, or involve DNA tests as the extreme requirement. Direct Thai relative's can help greatly.

@Richard *******

yes, she should be able to.

@Richard *******

learn the lingo first boy. This is basic stuff. What are you expecting from a law firm?

She needs to get her Thai passport which she will use to enter and exit Thailand. US passport to exit and enter the US. You don’t need a lawyer for such things especially one in the US. They will just fleece you and not do anything

yep I hear you. It's funny how Thailand wants to be this new developing country over all it's neighbors but still have what you call "Thai logic". That's what makes Japan and Korea superior as a nation. They have a national standard and pride. Lived in Japan for a few years. Absolutely loved it but it's expensive unlike Thailand. Great point on Thai logic . Prostitution is illegal but they promote Nana plaza as the sex capital of the world. Perfect "Thai logic".
