How often do I need to renew my visa in Thailand after receiving a short-term visa instead of a DTV?

The user received a multiple entry tourist visa (METV) with a validity of six months instead of the desired five-year DTV visa. They are inquiring about the renewal frequency for their visa. According to comments, a METV generally allows a 60-day stay initially, which can be extended by 30 days at an immigration office. After this period, the visa holder must leave Thailand and re-enter to receive another 60-day stay, effectively allowing for potential stays of up to nine months if managed correctly. Several commenters noted the importance of meeting financial requirements for visa applications, which may have contributed to the user's unsuccessful DTV application.
