Just submitted our application for the SETV at Savannakhet today. We submitted flights out of thailand, bank statement and 3days accomodation booking, 2 passport photos and photocopy of passport and no questions asked. Only issue was that they only accept baht and no USD so had to quickly go and exchange some usd to baht :) (1000baht)
Thats what i want to hear! I have no issue with showing a bank statement, it's just a pain to withdraw money from an ATM in Laos to get the 500euro equivalent (x2 as we are 2 people).
Do you know if they ask for any flights out and accomodation bookings? :)
