That’s really all you’ve got? “What about when you file the 90-day report online?” Do you honestly believe they don’t check when you show up in person? You’re exactly the kind of pitiful foreigner Thailand has far too many of — clueless, desperate, and clinging to your little loopholes. Deep down you know your dodgy stay is going to catch up with you, and when it does, you’ll be the last one to understand why.
You are mistaken in this matter and appear not to be properly informed. Several individuals are requested to present their bank book at the time of their 90-day report following an extension. This requirement is unrelated to the 90-day consecutive stay reporting itself; however, one may be asked to provide the bank book simultaneously with the 90-day report. Occasionally, a note regarding this is entered into the passport when the extension is granted, though not always. I concur with the previously stated point. If you do not have anything constructive or reasonable to contribute, it would be best to refrain from commenting.
