@Keef *******
you applied PRE-covid shit show and right now if you're gonna use HCMC you make an appointment or you don't get in the gate. Hanoi is walk up service
Also READ the requirements carefully because they are sticklers about it.
Those are not the soft-touch, skate up, apply, get the visa consulates like they were pre-covid. They want you to meet the requirements or they don't give you the visa
