Vietnam visa inquiry

Hi,

I will be  flying from Bangkok to Hue via Hanoi. Is it still possible for me to get the visa online approval? Will I go through immigration in Hanoi or Hue if my stopover is 2 hours? 

Please let me know before I apply online.

Thank you 

Dear Tee

We are afraid that 2 hours will not be enough since you will need to get your visa stamped at Hanoi airport  before you fly to Hue.

In this case, please be advised that you obtain your visa before you travel to Vietnam.

Best regards,
