Looking ahead to applying for a NON-IMM O-A visa, I note that, regarding financial requirements, the UK embassy now states:
'Financial evidence showing monthly income of not less than 65,000 THB (approx. £1,625) or having the current balance of 800,000 THB (approx. £20,000), e.g. bank statements, proof of earnings, for at least 1 month
Copy of evidence stating that applicants have insurance as per stipulated by the Office of Insurance Commission and health insurance of Thailand which covers COVID-19 related medical expenses, both inpatient and outpatient, no less than 100,000 USD for the whole period of your stay in Thailand.'
Specifically, the insurance requirement now seems to say that a single policy is acceptable provided that it covers the whole of the stay (one year). Does this mean that, for example, the free Emirates all-risk policy, with stated cover for 365 days, would be now be acceptable?
TLDR : Answer Summary
The financial requirements for the NON-IMM O-A visa in Thailand include a monthly income of 65,000 THB or a bank balance of 800,000 THB, alongside health insurance covering COVID-19 with a minimum of 100,000 USD for the entire stay. There's uncertainty regarding the Emirates all-risk insurance policy's acceptability due to its terms and the insurer AIG's unwillingness to provide a Foreign Insurance Certificate. Further verification of the Emirates policy's compliance with specific inpatient and outpatient coverage is necessary.
