Do my children need to accompany me when I apply for a tourist visa for my family in Thailand?

The requirement for children to accompany you during the tourist visa application process in Thailand depends on various factors including their age and the specific procedures of the embassy where you apply. Generally, children must be present during the online application, but they are not liable for any overstay fines. It's important to clarify the rules at the specific embassy, as some may require personal application while others do not.
