I will need to find schools for my children (ages 2.5 and 9.5 y.o.) after we arrive to Chiang Mai, Thailand and obtain ed visas for them. I will not be able to leave Thailand for 90 days to go to a Thai Embassy outside of Thailand because I have a new ed single entry visa. My question is can the kids' ed visas be applied for from inside Thailand?
TLDR : Answer Summary
The process for applying for ED visas for children while in Thailand can depend on the schools they plan to enroll in. It's important to check with those schools about their policies regarding visa applications. Some comments also suggest that leaving Thailand is possible if a reentry permit is obtained.
