Dear Khun May,
Thank you so much for you help. It is very much apreciated!
I looked on the Bangkok Bank website and found this:
http://www.bangkokbank.com/OnlineBanking/PersonalBanking/iBanking/BualuangiBanking/HowtoApply/Pages/Default.aspx
At the time of application I had an O visa.
If I understand the requirements correctly, the teacher that guaranteed me when opening the bank account could also do this for I-Banking? Can you verify this. I am sure she would be willing to provide you with a guarantee for I-Banking as well.
Thank you again and have a pleasant evening :-)
Sincerely,
Robert
PS: I will try to get on LINE if that is more convenient for you.
