The conversation revolves around the process of converting a DTV (Digital Nomad Visa) to a Non-B (business) visa and work permit in Thailand, particularly for teachers. It discusses whether it's necessary to leave the country for this process, the typical costs associated with the Non-B visa, and the challenges of conversion without a job offer. Participants highlight that the costs for the Non-B visa are often covered by employers and clarify that a DTV cannot be cancelled but may be converted at a local immigration office.
