I've been two times to SCB without any COR from immigration but my wedding certificate. Headquarters handled the approvals both times, took a couple of days. Third time the branch processed immediately.
I don't know if it's a common policy of SCB that headquarters is approving foreigners application requests, but it seems more professional than bullshit refusals from branches.
It's always possible, but it's up to the individual branch how they handle things. I opened mine at SCB within 1 hour but I had previously a savings and fixed deposit account already which both needed approval by HQ (a few days wait).
I wouldn't park much money on a FC account here, interests are laughable.
My local Bangkok bank wouldn't even let me open one on my non-o visa with a certificate of residence from immigration. The employee said : only for long term visas or education visas 🤡🤣
Kasikorn wasted 40min for all paperwork and pictures, but at the end denied because my name on marriage certificate was longer than on my passport (well I have officially 5 first names, but only the two first ones and the first letter of the 3rd one are printed on my passport) , they couldn't make sure I was the one married to my wife 🤣
SCB was the bank that didn't make problems, only had to wait for approval from HQ a few days. Opened after that also my Fixed deposit account and an FCD at their place 👍🏼
That was last year. It's like you read all the times, every office/branch , private or government are just ticking differently by making up their own rules, interpretating them differently or just by pire ignorance/incompetency.
Maybe you should stop arguing and give advice in a Disneyland group instead of here where terminology regarding immigration matters makes the whole difference.
