I got an ED visa in Hanoi from the Thai Consulate ( around the corner from the embassy) last month. Very straightforward no queues. Drop off documents before midday pick up visa the next day after 3pm. Providing all documentation is in order in and out both days under 15 minutes
They have sorted all the relevant documentation from the MoE it's just me being overly cautious and my natural worrying instincts that things can go wrong!
. It's my first time getting this type of visa so my head is full of questions as I don't want to get to Hanoi and find out there's a problem. I've lived in thailand for the past 2 years on a non o visa but as I've now started thai classes I thought I'd go this route for a change.
