Do I need proof of funds and an onward ticket if I have a Non-B visa, work permit, and re-entry stamp when traveling from Thailand?

A teacher in Thailand with a valid Non-B visa, work permit, and a re-entry stamp is advised to check the latest travel requirements regarding proof of funds and onward ticket when traveling to their home country. While some travelers have successfully used lease agreements and their existing documentation to suffice understanding, having around 20,000 THB in cash cannot be ruled out as a standard customs requirement. It is recommended to confirm with the airline or immigration office for specific entry requirements and regulations applicable for the return travel.
