Asking on behalf of a citizen of Taiwan entering at Suvarnabuhmi: Does the VOA fee of 2000 baht need to be in Thai baht or is NT$ accepted? How about the proof of 10000 THB funds? Does this need to be in baht or NT$ ok?
TLDR : Answer Summary
The Visa on Arrival (VOA) fee of 2000 baht must be paid in Thai baht; no other currencies, including NT$, are accepted. For proof of funds, it can be in any currency, but it must be cash if requested.
