My kids under 15 years old is on the tourist visa and they had stayed a week over due. My question is at what point do we have to leave the country to get them a valid visa. Is it asap or do we have X anount of days before we get a big fine?
TLDR : Answer Summary
If your children under 15 are overstaying their tourist visa in Thailand, they are not subject to fines, and children under 18 cannot be banned. However, it is advisable to leave the country soon to avoid passport stamping and complications with future visa applications. Planning to leave by the end of December is recommended to ensure compliance, especially if you have school obligations.
