For full transparency I own a Muay Thai gym in Bangkok.
We had students apply in HCMC and normally it's been a quick and easy process but there was a week where two students got additional requests that didn't make any sense. They resubmitted and got approved, after that one week things seemed to be back to normal.
We had one person apply in Japan as a non resident and get it but apparently they had to write a long essay and it was unlikely many others would get the same treatment. This was back in August early into the DTV.
Let me give an example of how training is at my gym, Tiger Eye. We have a mixed group of people. 40% of our members are affiliated with the United Nations, these are people who come 3-5 days a week and do a 90 minute session of Muay Thai which consists of a warm up via jumping rope, or partner drill followed by review of a technique, padwork and some exercises.
We also have in house Thai fighters who train twice a day, run in the mornings and fight every few weeks.
It depends on who you are and what your looking to get out of it. No one is going to force you to train and no one is going to treat you like it's boot camp.
Anonymous participant Thank you for the kind words. That is a wonderful compliment. I am glad people are being helped with their visas but the appreciation about my experience in the industry - that means a lot!
