Do I need to leave Thailand on the same day I cancel my work permit and non-B visa?

When you cancel your work permit and non-B visa in Thailand, it is typically required to leave the country by the end of that calendar day. However, it's important to verify the specifics with the Thai immigration office or consult with a legal expert to see if you can leave the following day, especially if your employer wants you to continue working until the end of your contract.
