I am currently on the 45 day visa exempt period and looking to get a educational visa "to study Thai". I speak Thai fluently read write etc so border testing isn't a issue. English citizen currently located in Bangkok. I am looking for some recommendations for the cheapest education visa institutes, or agencies, in Bangkok to get a 1 year education visa. I'd like some options and I can then go and investigate these. This will be the first time I am applying.

Thank you
