Managed to get our visa applications processed quite quickly. One for me, British Citizen, the wife who is an EU citizen and the father-in-law who is eu citizen but without the 2 year residence proof. Did the forms on line and visited the Friday before Christmas. Had a piece of paper missing, silly me, so the lady said "come back with the form, don't queue, just see me and I'll do it for you straight away", which was nice. Managed to get home and back again before the 4.30pm shut off and had my Visa done by the 27th of December and both the others by the 1st which was quite impressive seeing it was over the Christmas period. Off on the 21t with the father-in-law who has never been outside Europe and doesn't speak a word of English which should be fun but seeing there's loads of Russians there he should be able to talk to them.
The online process was a bit tedious and apparently they archive online forms which haven't been actioned at the VFS centre after a couple of weeks, so it takes a few minutes for them to retrieve them.
All in all, a fairly OK process and much better than queuing outside the Indian High Commission. Am def going to look at getting a PIO card though.
