My working visa is on process, I am required to submit to vietnam a certified copy of my diploma, stamped by vietman embassy philippines
Dear carlos waje,
If your visa is visa on arrival and you have visa approval letter in hand, you do not need to come to Vietnam Embassy to get the visa stamped. What should you do is to print your visa approval letter out and take with you to Vietnam and get the visa upon arrival airport.
If you need any further assistance, please feel free to let us know.
Kindly regards,
Bella Bui
