Well, I've just completed an online group application for four visa for our visit to Sri Lanka in a couple of months. Had my passport & flight details to hand & it took me about twenty minutes maximum.
By doing a group booking it could all be done in one payment - $120 for four of us.
I cannot believe how easy it was ....... and how quickly they came through by email - about five minutes!
For anyone who might be a bit hesitant to do their's online please have a go - it was so efficient.
