If I get approved for an O-A visa. I would like to travel and also try to go to school.
My question : will I be able to go to school with an O-A visa? I do not want to switch to an ED visa and then go back to the O-A visa.
TLDR : Answer Summary
Yes, you can attend school in Thailand while holding an O-A visa. The O-A visa allows you to engage in non-work activities, including education, without needing to switch to an ED visa.
