Is it true kids under 15 can stay on a tourist visa indefinitely, there is no fine or banning for overstaying on exit? We arrived on tourist visas, I will extend mine but there's no point in paying to extend his if I don't need to. He's 5 years old.
TLDR : Answer Summary
There is a belief that children under 15 years old can stay in Thailand on a tourist visa without facing fines or bans for overstaying. However, while some comments confirm this notion, others suggest it is more respectful and prudent to extend the child's visa to avoid potential issues in the future, especially if they plan to stay long-term or receive an education in Thailand.
