Yes, your name on the birth certificate isn’t enough if your child was born outside of marriage. As the child is over seven years old you can (as Robert said) go to the Amphur and register yourself/get the necessary paperwork. I would go to your local immigration office first though, make your intentions clear and ask them for an exact list of documents that they would want to see in order for you to apply.
that’s brilliant. The advice here has been reaching the Siam Tech forum, I put Robert’s TM30 post up there and have been advising people to join this group if they have a visa related question, thanks again Tod 🙏
yes, a tourist on a visa exempt stamp that’s staying at hotel that registers them would be covered, although they might be asked for some sort of proof of which hotel they are staying at. It could get Interesting for those ‘tourists’ that are staying in privately owned residences wishing to extend their visa exempt stay.
Don’t stress too much, I carried my old passport (with my visa in it) along with my new passport for several months before immigration put a stamp in my new passport linking my old passport number/visa. They’re correct it when you go to renew. Just carry both for now.
