How much money must I show in my bank statement for a 90-day Non-O visa in Thailand if coming from the UK?

To apply for a 90-day Non-O visa for Thailand, it is generally advised to show around £10,000 or approximately 30,000 THB in your bank statement, based on anecdotal evidence from expats. However, specific requirements can vary, with some individuals reporting needing as much as £22,500. It's noted that the scrutiny on financial proof may be increasing at immigration, particularly for different visa categories.
