the Vietnam option if it’s 48 hours might doing it but if it works out 5 working day to process you might have to pick up the passport after the weekend when you started on a Monday .The financial burden will be huge for most of them and the schools haven’t got a clue until now about these new visa processing requirements.
The convert in-country would be the easiest way and although on immigration web sites this is mentioned the school say it’s a no no when they ask immigration about this option.
I’m wondering how this will work out for teachers who will have to make a Non B visa in Vientiane or Savanaket and waiting there 2-3 weeks to get their visa processed and in many cases schools made mistakes with the documents provided,resulting in another 2-3 week trip to Laos.
