Is a proof of reservation sufficient for a Thailand visa application or is a proof of payment required?

The requirement for proof of reservation versus proof of payment can vary based on the type of visa you are applying for. Generally, most visas do not require proof of payment, but the Special Tourist Visa (STV) does necessitate it. For tourist visas, some applicants report being asked for full payment receipts and details, while others have had success using reservation confirmations from platforms like booking.com, which allow payment upon arrival. Ultimately, providing proof of payment may be beneficial to ensure compliance with visa requirements.
