Can I convert my 60-day tourist visa to a NON-B visa in Thailand or do I need to leave the country?

The process of converting a 60-day tourist visa into a NON-B visa as a teacher can be challenging. While it is theoretically possible to do this within Thailand, many find it difficult due to paperwork requirements. A colleague mentioned success in Bangkok with significant effort, but most Bangladeshi expats tend to return to Bangladesh to apply for the NON-B visa at a Thai consulate or embassy. It's essential that your employer assists with the application process, and the decision of whether to convert inside Thailand or to exit the country depends on their arrangements.
