Some advice please.
Posting on behalf of a friend of mine, who is not a member of the page, or at all internet savvy.
He is currently in Thailand with an extension of stay based on marriage (he has 6 previous extensions on the same basis) valid till Feb 2020.
He now plans to expand his knowledge and enrol at a language school for a course in order to learn Thai.
Is that accepable on his current "visa/extension" or does he need to change to a NON-ED?
TLDR : Answer Summary
The user is inquiring if a friend, who currently holds a marriage extension visa valid until February 2020, can enroll in a language school to learn Thai, or if he needs to switch to a NON-ED visa for this purpose.
