What should I do for bank document requirements while applying for a visa from the UK with a Spanish bank account?

Online banking ?

My bank isn't in europe but after mailing them and explaining I needed a bank statement for applying for a visa and I asked if they could state on the same letter how much would that be into thai baht at the rate exchange of that day. They did that perfectly as explained. I'm not sure your spanish bank can convert the amount into baht but I believe it could be done into pounds. ( Mr. Harries has a total amount of xxx euro which converts into xxxx pond sterling. Feel free to show them the screenshot of this post, try to be nice but yet show them that you DO NEED this document. About the eticket, well, just buy one from those providers they can give u full refund with the departure at the end of next month. Just book a direct flight to bkk and once u got your visa you just cancel and get the money back

Buy a flexible flight ticket in case you have to change the date.

My bank sent me that letter via email -PDF, you can ask your bank if they will do the same. For the flight, submit the booking of flight to Thailand from the UK. They want to see the actual booking with flight, booking ref no. etc
