I opened an account with Bangkok bank in Pattaya last week. They looked at my passport, which had a multiple entry non immigrant visa. Told me to get a Certificate of Residence, which I did. That was all that was needed. No hassle.
I remember in 1980 I thought I would give this a go. The guy, who they were just bringing back, crash landed on top of two beach umbrellas. I turned around.
Still have never done it.
