Can I extend my visa by enrolling in another Thai cooking course after my current one finishes?

The user inquires about extending their DTV visa after completing a 6-month Thai cooking class, asking if they can enroll in another class to validate their visa while only staying in Thailand for up to 40 days per visit. Responses indicate that once the DTV visa is issued, there are no ongoing requirements from immigration, though the validity lasts for 5 years. However, some users note that immigration authorities may not recognize the DTV for extensions, suggesting alternative methods like 'border bouncing' to maintain visa status.
