Wait, you will give birth in Thailand? Won't that make your child a Thai citizen? How will it be admitted into your country? Just curious how that works.
12 years ago you could go to a hospital in Bangkok with an overnight stay and a catscan for ~ 200 US dollars.....until they were taught the insurance game. You know Thais aren't falling for it, right?
