I asked for a "Certificate of Residence" in Chiang Mai and Immigration asked me what I needed it for. I told them it was for opening a bank account and getting a motorbike licence. I subsequently received 2 documents - 1 for each and they are specific for each. Cost 40 baht altogether!
For those who may gain some insight from my first 90 day report here in Chiang Mai :-
1) Went to the Immigration Office at Central Festival and NOT the airport,
2) The reception staff only required passport plus 1 copy of the TM47 (No copies of the TM6 departure card required, nor copies of passport bio page, nor copies of "stamped in" date, nor photos),
3) The queue was non-existent,
4) The entire process took less than 5 minutes,
5) Walked away with receipt - report again end of September.
Non O-A visa requires health insurance to match the validity of the visa. For example I was able to get stamped until 31 March 2023 which is when my insurance runs out for the initial 12 month period.
I have just arrived in Thailand on a Non O-A retirement visa from my home country (Australia). This involved months of preparation and organisation (medical, health insurance from a Thai provider, police clearance check, Thai pass etc). The process was time consuming but simple. I am now stamped in for 12 months with no requirement to have large sums of monies transferred to a Thai bank account apart from what I need to financially live here in Chiang Mai.
I provided a camera upload of my vaccination certificate only - no QR code and no passport number on the vaccination certificate. Thai Pass submitted and approved in 3 days. All my uploads were from my phone camera - no screenshots!
