Do you face fines for not submitting your 90-day report while on a DT visa in Thailand?

Failing to submit the 90-day report for a DT visa may result in a fine if you visit an Immigration Office for other requests, as they might check for compliance. However, at border controls, such as when departing the country, immigration officials are not likely to impose fines for overdue reports. It appears that the enforcement of fines can vary, depending on individual circumstances.
