They have a list, and it says unser 4. Financial evidence "..., e.g. account statement for three months,..." For example, does not necessarily mean that the three months are mandatory, and it could refer to a bank statement, but possibly also to other types of customer accounts. That is what makes me think that it might actually work after all.
We would like to stay for up to a year and do not want to make frequent trips to neighboring countries. There is also no guarantee that the 60-day stay will remain unchanged. If, during our trip, the allowed stay is reduced to only 30 days plus a 30-day extension, it will be difficult for us to reach a total stay of 10 to 12 months.
Additionally, we believe that the DTV visa is a fantastic opportunity, not only for our current plans but also for future stays in Thailand. We have been visiting Thailand every year for the past 12 years, and this visa would make it much easier for us to continue enjoying this wonderful country.
