20 years ago I talked down about a Thai Bargirl in front of hi so wealthy Thai lady who angrily put me in my place by telling me that girl never had the opportunities I grew up with

Bangkok Bank head office in Silom. They asked my budget I said I was looking at around 15 million baht and wanted to be able to pay a deposit immediately if I found what I was looking for. I opened the account with 5000 baht

First off keep every picture and letter or other form of communications you ever had with her. Your chances will increase greatly if she has good reason to come back to Thailand...ie. She owns a house, has a child not going with her, owns land. Has a decent level of education, has a job and a letter from her employer stating she has time off due. Has a bank account.with savings...if on the other hand she worked in a bar and has none of the above...don't waste your time

Go to a bank and tell them you want to open an account "for the purpose of buying a condominium" I did that and walked out with a debit card and bank book 15 minutes later
