What should I do about my visa if my passport renewal delays past my stamp expiration in Thailand?

The user inquires about the implications for their immigration status if their passport renewal in Bangkok does not return before their visa stamp expires. The responses indicate that the individual will enter overstay status until their passport is returned, necessitating a visit to immigration to address this.
