What I did was apply for the 90 day non o visa from the Thai embassy in London. I was able to open a bank account with my visa, passport, rental agreement and TM30. It was all fairly easy. I stayed in an air b n b for the first week while looking for a 3 month rental condo before I could open the bank account. Also needed a thai cell phone contract. Then I reached out to

who sorted the 12 month retirement extension. They also sort out the 90 day report for me. Reasonable price and no where near the 60k Bhat quoted in one post. I know some say just do it yourself but as a retiree I’d rather pay to avoid queues and using my time. It’s up to you but I’m really happy with the haste free service.
