Do I need to provide proof of onward flight when applying for a SETV visa at the Thai Consulate in Yangon?

The inquiry revolves around whether a US citizen needing to apply for a SETV visa at the Thai Consulate in Yangon must present proof of an onward flight from Thailand. Responses highlight that confirmed airline tickets for departure from Thailand or, if crossing by land, accommodation bookings in the neighboring country are typically required. Ambiguities in the Thai Embassy guidelines are noted, particularly relating to whether the requirement refers to exiting Thailand after the visa expires. Overall, clarity on these documentation requirements is sought.
