What are the requirements for 'proof of funds' when applying for a 60-day tourist visa to Thailand?

When applying for a 60-day tourist visa to Thailand, 'proof of funds' usually includes a bank statement proving you have sufficient sufficient financial resources to support your stay. This does not necessarily require an official document; an online bank statement is typically accepted, but it is advisable to have it printed and presented neatly. It is not specifically required to have a Thai bank account, as funds can be shown from accounts in other countries. As for currency exchange in Chiang Mai, many locations can provide crisp U.S. dollars, which might be necessary for visa applications in Vietnam.
