Do I need to cancel my visa before leaving Thailand if my work permit will be canceled after I leave?

The user is leaving Thailand with an active work permit but without a re-entry permit, and they are uncertain about visa cancellation processes. Comments clarify that the Extension of Stay related to the work permit must be canceled before departure, while the visa itself may be automatically canceled upon exit if the work permit is also canceled. It's noted that there's a distinction between the work permit and the visa, with different rules applying to each. Additionally, it implies that an overstay could occur if the user does not precisely follow cancellation procedures.
