I couldn't find info on it... I email the evisa team, but apparently you cant extend an evisa. Hopefully I get approved the day before or day of my flight, because most Aussies say it takes about 5 business days. I'm really hopeful. Have you ever heard of anyone getting called in for an interview in Hanoi? And is there any accounts of people getting asked to show their passport pages to the Hanoi office? The whole reason I picked this location is because it seemed a little more relaxed...
