Bahnhof Strasse
Met up with Hannah Courtoy a week next Tuesday
I think I've reached the limit of my knowledge here; maybe some of the better informed folk like Bahnhof Strasse might be able to help with that?
AFAIK the non-Schengen countries all have the same rules as Ireland, i.e Schengen to Cyprus = passport/id needed and a Schengen visa* is not valid.
Schengen visa is for people who need a visa to visit a Schengen country, e.g. a Mongolian national. If that national wishes to visit multiple Schengen nations they must apply for the one they intend to visit first. They can then travel around the Schengen zone without need for additional visas**, or indeed the requirement to show a passport to pass between those states. Should they wish to visit a non-Schengen EU state they will need to show a passport to enter and if applicable, be in possession of a visa for that country. Where Ireland is a special case (and the UK was until it left) is that there is a Common Travel Area between the UK and Ireland and no documentation is required to travel between the two, however should said Mongolian have a visa for Ireland and wishes to visit the UK they would need to obtain a separate visa for the UK, there is no Common Travel Area visa. Of course the need is most commonly the other way around, you have a UK visa and wished to visit Ireland, some people have suggested flying to Belfast and getting on a train to Dublin, there are occasionally checks on the train and on the roads too, and should you be found in Dublin with no valid visa you will be an illegal immigrant and expelled, not to the UK but to your native land.
**The Mongolian travelling band with their Schengen visas will still need separate visas for each country they will perform in, should anyone get over-excited at the discovery of the Schengen visa.
