On a retirement visa is it possible to add your child? Are there any other visa possibilities, other than education, for a child?
TLDR : Answer Summary
It is possible to add your child to a retirement visa until they reach the age of 20. Apart from education visas, options for children's visas are limited. The Thai Elite Visa may be a viable option for those who can afford it, as well as the DTV (Digital Nomad Visa) if the family can show 500,000 THB in funding.
