With Ho Chi Minh City being the most preferred port of entry, I am posting here:
I have previously posted having a 30-day E-Visa already in hand, and having a 6 weeks trip end of May 2022.
So I have applied for another 30-day E-Visa and successfully got the payment processed and awaiting Electronic Visa sent to me to print out.
Knowing there are currently no other form of VOA out there for tourists such ad myself. I will update if I have another 30-day E-Visa in hand.
