Hi, Do I have to pay service and stamp fee in USD or I can pay any currency? And, does it need cash to pay stamp fee at the airport or credit card is accepted for payment

Dear, Danie Ryan, Thanks for your concern! The service fee and stamp fee can be paid in any currencies. However, USD is the most preferred. + Stamp fee must be paid in cash because you have to directly pay to Vietnam Immigration Officer at the arrival airport to get your Vietnam visa stamp. We hope this information is clear and helpful for you. If any unclear, please let us know. Have a nice trip to Vietnam! Vietnam-Evisa.org
