What are the requirements for my Canadian-born daughters to move to Thailand with me when I retire?

The individual is considering the implications of retiring in Thailand and the possibility of his Canadian-born daughters moving there with him. Since their mother is Thai, the daughters are eligible for Thai citizenship and can apply for Thai passports. The process may require some documentation, such as their birth certificates and, potentially, their mother's Thai ID. Although they are over the age limit for sponsoring a parent for a long-term visa, they can independently apply for their citizenship and passports.
