Hello, if I enter Thailand under the visa exemption program, do I need to leave the country to apply for an ED visa or can I apply and have the visa issued within Thailand?
TLDR : Answer Summary
It is possible to apply for an ED visa from within Thailand if you enter under the visa exemption program, but the approval may depend on the school you apply to. Some language schools in Thailand may assist with the visa application process while you are in the country.
