Do I need to prove financial requirements for my DTV visa extension every six months or just once for five years?

The answer: just prove first time and done!

After the DTV Visa approved, it valid for 5 years. Once you enter Thailand you have to countdown from 180,179 and you have to leave Thailand before or on the day count down to 1. if you reenter Thailand by the DTV without additional paper the countdown clock start again. Now you can continue extend after day 0 buy paying extension fee at immigration office (before day 1 of course - just before 20 days left- recommend)

This VID may helps

For re-entries currently nothing additional is required. For in country extensions nobody knows the cost or requirements as Immigration is silent on the subject. Despite repeated requests Immigration have not published any details.

As it stands currently you don't need new paperwork or bank statements on extension or re entry.

There are lots of rumors that immigration are planning to move the goal posts and start requesting new courses.

I personally think that won't happen as it would be a massive betrayal. But no doubt visa agents and immigration are dissatisfied with the DTV so it suits them to spread these rumors and in reality we won't really know until someone extends in a few months time.

My gym is looking at ways to protect my customers from this unlikely turn of events ... not quIte sure how we will do it but will look at course extensions with additional paperwork for a small admin fee
