Update: Me and my wife went to kasikorn in another mall, this time we brought them a swedish government issued letter of house hold registration which according to their website they should accept, with my current thai adress which is only way for them to see my adress anyway. Not on id card swedish nationals NEVER have an adress on a id card, I said I had to move my adress to thailand by law to even get married here. I no longer live in sweden. Its all in the system on a government website site there. They assume other countries work the same as thailand. They even asked me to see my house registraton book then when we convinced them a sweden id didnt have a adress on it... Which sweden dont have lol, neither can u request an ID card with an adress on it from embassy either. I even showed an example how a real issued sweden id looks like, and it looks basically same as my passport but just id format.. So why shouldnt an passport be enough. Even if i brought an id im positive they still wouldn't allow me. After moments of convincing Kasikorn said they would MAYBE accept it if my government letter was stamped by a swedish consulate.. I dont like to hear maybe soo i went to another bank. (But good news when i went to another bank) That i already had a good feeling about was Krungsri, she looked through my all documents and everything looks fine but they needed a letter from immigration for me to open the bank, i had one issued for kasikorn, but they said I needed to update it for krungsri to open it which will be on Monday. I wanted to open kasikorn but i guess Krungsri is good enough :)
