because you go in a foreign country to do it when you want to set up your life in Thailand! I'm in Jakarta right now and i'm hating it! So hot, noisy, and messy city! Is not fun!
Isn't Jakarta moving to E-Visa on 22 October? And they say that with E-visa may take longer and it easier that they will deny your application if you do the slightest mistake
This was an E-Visa? For even a slight error they can just cancel your request. I don't think is formally correct to say that you got "denied", probably they will just "cancel" it.
This mean that you did a formal mistake but you can apply again, it does not mean that you don't have the requisites to obtain the Visa.
It happened to me too months ago, they "cancelled" the request... they say that their system doesn't allow any changes, they can't change what you put. So if the information is wrong, even a small detail, they will delete your request.
