What documents are required for an Indian traveler to obtain a Thailand tourist visa and what is the approval ratio?

An Indian traveler seeking a Thailand tourist visa needs to prepare several documents including a filled application form, a recent photograph, a bank statement, a round trip flight ticket, and a hotel voucher. Additionally, cash or travelers cheques amounting to at least 20,000 baht (or equivalent) may be required upon arrival. The approval ratio for tourist visas is reportedly very high, virtually 100%, as long as all requirements are met.
