You can do the year long language visa for 2 years, learn thai, then, japanese/english/chinese. However, if you go to university you can get 5 years. As others mentioned they will test your thai and you can not use english if you are already NES. Elite privilege visa is another option or just do the dtv. Its a 5 year visa.
If you plan on staying in Thailand long term you should definitely take a Thai class either way. Its like a whole new country once you can speak a good amount of Thai. Good luck
use it all the time. Your "10%" theory is demonstrably false. Costs 1.50 pound to transfer a million and a half with an exchange rate close that, if not equal to, in person cash exchange. I suggest you put on your helmet, have some extra crayons at breakfast for confidence, and the try growing up a bit. đź¤
You should always have it. When it comes to anything thai govenment use the better to have it and not need it than to need it and not have it rule. That said the nice ladys that check the documents before you get your second ticket have justbasked me where I am staying and written it for me in thai. Never needed tm30. American Passport.
While I havent seen it yet at my school, from what I understand all the schools have a "meh" class that they shove the ed visa riders into. Wherever you do end up going just make sure when you go to sign up you let them know you are serious about learning Thai and intend to be there every class and they should make sure you dont get put in their meh class.
