First time i applied myself and it was rejected. You have to prove that she has incentive to go back home after trip. Then i used an agent in Thailand and was successful. Third time i used the agent again and was successful. I think it might get easier once there is a track record of returning.
correct. I have an OA which can only be applied for outside of Thailand. I am required to have insurance, but I do not need to keep 800k THB in a Thai bank account (although I did have to show that I have the equivalent in my bank account at home)
