. . ..sorry, I have no idea . . It was a letter all in Thai . ... immigration officer verified it was sufficient to present to the bank to open an account . . .
Yes they knew, as I had to produce copies of my passport showing my 30 day extension and biometric page
Yep came in 30 days visa free, and obtained the 30 days extension ( same immigration office )
I opened one on a tourist exempt ( 30 days extension ) after visiting numerous banks
( in pranchinburi) and being declined, went to immigration office, filled in the appropriate form, including details of girlfriends address, copies passport details page and extension page . . the immigration officer gave me a letter ( in Thai ) and told me in very well spoken English that with this I could now open a bank account . . . Went back to Bangkok Bank, and with the said letter and further copies of documents was able to open an account . . without the added insurance,
