what is tourist visa approval procedure and visa processing fee for Bangladeshi citizen for single entry?

Dear Mr/Ms

Thank you for your question

Could we ask when you arrive in Vietnam? we would like to inform with you that you can apply online with us but the procedure takes 7working days and you have to send us your flight ticket, hotel booking and passport scan via our email at:    visa@vietnam-evisa.org      then apply online at : Vietnam-evisa.org/apply-visa.html

 We then will send you the approval letter via your email then you can print it out and get Visa at Vietnam airport

Best regards

Hanah
