Can I get a 7-day extension when canceling my Non-Imm-B visa and work permit in Thailand?

The individual plans to cancel their Non-Immigrant B visa and work permit to leave Thailand but is uncertain about the process. According to responses, you need to cancel the work permit and the visa at the same time. While it is commonly thought that you can receive a 7-day grace period upon cancellation, clarification indicates that this is not a true extension; instead, it results in a stamp giving you 7 days to depart the country. If under a valid visa, you cannot cancel it directly; instead, it becomes invalid upon leaving without a re-entry permit.
