UK citizen and passport holder, retired and living full time in Thailand.

O-A Visa and extensions since 2014. I tried to upgrade my health insurance coverage from 1 million to 3 million Baht, but was refused. Therefore I do not meet the health insurance requirements for a Non O-A extension. (I have International health insurance elsewhere).

Therefore when I returned from the UK from a holiday in December, I cancelled my Non O-A extension and insisted on a 45 day visa exempt, which was granted at Suvarnabhumi after considerable discussion. My plan was to apply for a Non O Visa in Thailand.

Today at Phetchaburi Immigration my application for a Non O was refused, because they insisted that I need to show that the 800,000 Baht came from outside Thailand. My 800,000 Baht has been sitting dormant in my Fixed Account since 2014 and I would have extreme difficulty showing the original source of the funds.

Therefore what should I do?

A) Phetchaburi Immigration suggested I leave Thailand and get a Non O in Laos. Is this the best option of nearby countries?

B) Transfer the 800,000 Baht to the UK and immediately transfer it back to my Thai Bank, showing evidence that the funds came from overseas.

C) Provide evidence of historical regular monthly income from the UK to Thailand via Wise. I guess they would require a 12 month statement? Would I require then to continue with monthly statements for a year after the Non O was granted? I want to return to the 800,000 Baht method as soon as possible.

D) Use an agent.

Any suggestions or comments gratefully received. I have a 30 day extension of my visa exempt until mid February.

Many thanks in advance.
