Thought I’d share my experience of opening a bank account today for a marriage visa on a 90 day non o for anyone who may be in the same situation in the future as I’ve never came across this what happened to me today on this forum in the past
9:30 went to the Kasikorn bank in Prasat with my wife blue book her ID her passport my passport non o visa printed off certificate of residency from Surin immigration marriage certificate and was told by the assistant manager to come back after I get my extension
I explained that I needed the bank account for the extension but she was not interested just adamant I came back on my next visa so we just walked 
So we went to the Kasikorn bank in Surin were they seemed to accept everything I had and was looking promising until the guy said the residency letter said to open bank account in Prasat so couldn’t accept it so had to go back to immigration who done another letter of residency
Went back to the bank in Surin and started the process again and again was looking promising until a member of staff noticed my passport number didn’t match the number on my wedding certificate
Explained we’ve been married 20 years and this was back in 2006 and I’ve had 2 passports since that one but they insisted I needed my old passport to match the wedding certificate
So they then told us to go to the local registration office and get them to change it and stamp it which I knew they wouldn’t do but my wife said we’l just go and see

Just like we thought no chance they were going to do that for us so got sent back to the bank with the number for the woman we dealt with at the registry office so she could tell them herself that this wasn’t possible
The bank then apologised and said I couldn’t open an account with them unless I could prove who I was by my old passport from 20 years ago which I will still have back home in England
So driving back home to Prasat and thought I might have an old email I with it on so I eventually found an email from back in 2011 with my passport so we went back and they accepted that and eventually after 6 hours trying opened a bank account for me 😀
So even though I had everything needed to open an account only a 20 year out of date passport made it happen
Glad we got there in the end although very frustrating at the time the staff were very helpful and apologetic and just following rules from whoever was directing them from head office
