It looks like a mix of Non O and Non OA requirements. OA allows 1 year of stay. The income requirements are for the OA. Also, OA requires a higher limit for Health Insurance(3 Mil Baht).
The OA Visa is great. I have obtained 3 in the past. But keep in mind the mandatory health insurance requirement(now up to 3 million baht in coverage) might make it a deal breaker for some.
Possibly the Embassy wants to the know the source of your monthly income. I have applied for several OA Visa’s from the Los Angeles Thai Consulate and they require an Income Certificate to prove the 65,000 Baht in monthly income. I have never submitted bank statements for my past OA applications and all have been approve.
Clinics that deal in occupational medicine or clinics that assist international travelers could work. I got my first OA Visa Medical Certificate completed at a clinic that conducted occupational rehab and medical services. The clinic actually conducted the blood tests and even did a Chest X-ray. The cost 5 years ago was about $300. The challenge might be in getting the actual form signed by a doctor because it both English and Thai. At first the Doctor did not want to sign it because he did not what the Thai words said. But in the end he signed it and the Thai Embassy accepted this form.
Here is the key line about applying for a new Non OA from a Thai Embassy/Consulate: – an income certificate (an original copy) with a monthly income of not less than 65,000 Baht; or
– a deposit account plus a monthly income totaling not less than 800,000 Baht. In Mr. McManus' case a document from SSA would suffice. I have applied for 3 OAd's in the last 5 years and a letter from my Government Pension board certifying that I make more than the min 65,000 Baht in equivalent US Dollars was always accepted. The 65,000 Bath international transfers applies if one applies to extend the OA at Thai Immigration.
100% True. Got a new OA in Jan at the LA Consulate. Upon arrival at BKK in Mid February immigration stamped my passport until the end date of my health insurance policy. Also, I purchased a policy from a Thai Company that meets the OA and Covid 19 coverage requirements.
