People love to make assumptions based on their own experiences. But let's be honest, the DTV is brand new visa... I've spent 13 years here on a legitimate visa with zero red flags, leaving and re-entering over 100 times, most of the time without any questions. However, I was questioned twice but was still granted entry as I was meeting all visa requirements. Immigration does its job like in any other country.
Correct. A work visa is immediately canceled upon losing a job, and a marriage visa is immediately canceled after a divorce in Thailand. These are due to the requirements of each visa, regardless of whether the visa is valid for a year.
You're right. Over time, I've learned how important it is to balance the odds here. The notion of a "genuine visa holder" isn't the same for everyone, and most people assume they fit this category once they obtain a visa. However, that’s not necessarily the case, as maintaining the requirements (as defined by immigration) is another matter. Surely, most people who meet the requirements would never face questions, but random checks are still possible; that's the job of immigration.
