I stayed in Thailand from April 2019 to January 2020 on my ED visa, applied it through a language school in Bangkok, got 90 day at first then extended it 3 times for 60 days each time, and I left before the third extension expiration date but not calcelled it.
I read in another thread mentioned that you have to cancel your ED visa before leaving Thailand, also came across posts somewhere else about this but I always thought it's about students in universities, because never the language school or the immigration officer told me anything about ED visa cancellation.
I'm thinking about going back to Thailand in May, is there gonna have any problem at the immigration?
Anyone had any experience similar to my situation? Any information related would be much appreciated, Thanks guys.
