You can no longer obtain a VISA for a single member country as that would be pointless
I believe you can but it seems to be mostly Finland and Eastern European Countries to allow Russians across the border for relatives etc and certain boat cruises. You can also get transit visa's for boat crews which are only meant to be to get them from the dock to the airport and transit home.
If you end up up off route, there is an instant sense of humour failure by immigration.
The whole immigration thing is a bit of a nightmare once you step away from mass transport and into the realms of charters and personal transport. And its always the PIC thats held responsable.
