I think we all been in Thailand long enough to know that what we are told by one officer at one place is not necessarily the exact way it is everytime right?
I was told at a driving school last week that they will give the 5 year license for DTV holders.( after the initial 2 years) Was in Chiang mai .. I guess as most things no set rules.
John Grey not always.we have had applicants ask us for documents because the embassy rejected the first school they used. But told the applicant to go find another option. There are no set rules it vary from embassy to embassy and case to case.
Most gyms have compliance to either or all of the following government agency's
1.sports authority of Thailand
2. Board of Boxing sport
3. Ministry of Education
Most embassy accept one of the above but sometimes they ask for a particular one, sometimes they want all 3 , sometimes they ask for business documents ( gym should be a Ltd company)
Like most things embassy related there is no set criteria.
Just try to find a gym with as much compliance certification as possible
if you border bounce every 6 months you don't have to buy more muay thai courses but if extend at immigration after 6 months you might need a new course
