I have just converted to O visa, because the insurance I had came with so many exemptions as to be useless, & expensive. Better to keep the money to pay for emergencies.
I’m going through the same process in Chiang Mai. I just got back on visa exempt, is there a minimum waiting period before I can apply for the non-O? Also, do I need full banking details for the initial application (I already have 800k in the bank for the required period)?
If you’re doing a 90day report online you will need an up to date tm30. I was rejected for one night in a hotel in Chiangmai (I live in Chiangmai) 3 years ago. The local immigration office said the new stricter rules came from Bangkok. Renewing TM 30 was easy though- just showed my old one & passport, no landlord needed.
