Just to contribute, I received a notification and email from Bangkok Bank to update my information (itโs been 4 years since the account was opened with an ED visa and my very first condo address upon arriving). I showed up with my TM30 for my current address, the lady looked at my DTV, and she only asked me how long the visa is valid for. I answered, "5 years in 6-month increments," and I just signed all the documents for the address change, and that was it.
