Harsh, but I complied with your rule. I just wanted to show the information about it. It's called a Guardian visa but yeah it's actually just an extension one can get as it states that a Non o is required to get this kind of extension which was my enquirey:
"Along with the student visa of the child, the initial visa can be extended into a Guardian visa 21 days before its expiration and once all the requirements have been met. This is done at the Thai Immigration office."
The applicant has to be established the following:
Birth certificate of the child as a proof of relationship to the child.
Admission Letter and Enrollment Form as proof of the child’s enrolment in a school in Thailand
Deposit of THB 500,000 in a Thai bank account so you would have to set up your Thai bank account.
So all I'd need to get this kind of extension is a birth certificate to show my relationship and a letter from her school. It doesn't say anything about family courts and legalisation of parent responsibility...
I see, well I'm truly screwed then as my wife has just left me, leaving my daughter in my care. So I either go to Ho Chi Minh or Pnomh Penh every 3 months and pay for a new non o visa or survive for as long as I can on as many SETV I can get with extensions. Greaaaat.
Tony I'm in the same situation as you. I have a Thai wife and half daughter too. I think if you are travelling with them it will be fine. I've never had a problem. They target lone travellers who have many tourist visas. But I'm travelling alone.
I see so immigration just transfer over the entry stamp and extension stamp. I'll bring the old passport over to the airport just in case they ask questions or if they want to see the visa. Thanks for the info.
