What is the part you don't understand? The course is the reason itself you get the DTV softpower visa, just like a job with work permit is the reason for a work visa. When the job stops, you cannot use the work visa anymore to visit the country. DTV is not a kind of entrance ticket for 5 years as a lot of people here seem to believe. It is a visa valid for five years and aimed at people who want to do one or more softpower activities in periods of up to half a year. There is no need for a 5 year course, you can also have several courses during those 5 years, but should not be in the country at the periods in between. Most people need to periods in berween anyway to make money in their home country, because working in Thailand is prohibited on DTV.
the course is the reason for granting your visit in Thailand, no course means no reason to visit Thailand, just like not working means you cannot enter on a work visa, not folliwing school you can not enter on ED visa, not married you cannot enter on a marriage visa. Visa requirements clearly state what is needed.
where did you get information the visa requirements stop before the visa ends? It is normally in the whole world when you get a visa the requirements are for the whole visa period, so when this Thai DTV was different they would mention that somewhere, I did not find, and up till now nobody could show me where that exception is mentioned, so it would help very much if you could.
ongoing course participation now is a visa requirement, it is just not enforced when you get in the country, if they want they can check anyone entering the country without changing one rule.
Do banks in your home country not allow you to withdraw money abroad? Then the problem is not with Thai banks refusing to open accounts for tourists, but with your home country bank not allowing tourists to withdraw money abroad.
Anonieme deelnemer 166 The visa is in your case for attending a course, when the course is finished, there is no reason to stay anymore, so in case they check you, you might have a problem because you abuse the visa.
