Do you need to show an onward ticket every 60 days when on a METV in Thailand?

When traveling on a Multiple Entry Tourist Visa (METV) in Thailand, it is generally not required to show an onward ticket every 60 days. Although theoretically, proof of onward travel, accommodation, and sufficient funds (20,000 baht) may be requested upon entry, in practice, immigration officials rarely ask for these documents, particularly for first-time entries. Extensions of stay also do not typically require an onward ticket, but immigration authorities retain discretion to ask for further documentation.
