, I've opened my Bangkok Bank account at Sampran, Nakhon Pathom province, on September 2020; they asked a copy of my passport, legalised by my embassy, and a deposit of 10.000 bath.
At time I had the tourist visa, expired, but I was utilising the Covid amnesty.
On beginning of 2021, when I renewed my passport, getting the retirement visa, the Bangkok Bank has registered it, without showing an other legalised copy of the new passport.
