I applied in London through Soft Muay Thai. After 5 days, they asked me to provide some additional documents. I sent everything they requested: an official letter from my bank confirming that the funds had been in my account for at least 10 days, a bank statement with the relevant deposits highlighted, and a flight ticket to Thailand. After submitting the additional documents, my visa was approved 2 days later.🥳🥳🥳🥳🥳🥳 I should print it out and show it to the IO on arrival, is that right?
