I have been doing quite a bit of reading on this and still not 100% decided which way to go.
If I go to the Vietnamese Embassy in London via post each visa is £60 so for 3 of us £180 (not that cheap) however if I use a VOA its $45 each (approx £29) + cost of letter/service approx $15 each (approx £10) so a total cost of £39 each - therefore a saving of £21 each.
The only potential downside is waiting at HCM when we arrive if it is busy!
I have read it is all very easy and have no worries making sure I have the cash is USD when I land, but it is the choice of provider for the letter to obtain the VOA.
I am aware of the advertising regs on here so if anyone has used a particular website and had no issues could you please direct message me via here so we don't look to break any rules as I appreciate it could get flooded with adverts!
Thanks in advance
