What should I do if I lose my passport while on a DTV visa in Thailand?

If you lose your passport while on a DTV visa in Thailand, you will need to follow a series of steps. First, obtain a police report about the lost passport. Next, apply for a new passport. With the new passport, visit the immigration office along with details from your old passport and your visa application documents. It's suggested to check with your embassy to update the visa details from the old to the new passport. Just receiving a new passport does not automatically transfer your visa; the immigration authorities will need to be informed.
