Hi, ksand24. When you say "through" Ireland does that also include flight connections? For example, if I were to fly from JFK in New York, connect in DUB, and fly immediately onto MAN(chester)... is that acceptable?
It includes ANY flight that lands in Ireland, whether a connection or the final destination.
So, you CANNOT connect in Dublin... because you will go through Irish immigration in Dublin and you will NOT to through UK immigration in Manchester. Therefore your visa will not be stamped and you won't be able to pick up your BRP card.
Basically, DO NOT fly Aer Lingus. It might be cheap, but it will cause all kinds of issues with your visa.
It's been awhile, but I have connected in DUB before to go onto LHR and I don't recall having to go through Irish immigration as I transferred planes.
You definitely go through Irish immigration...there are no immigration controls between Ireland and the UK, so you go through immigration in whichever country you land in first.
I flew Chicago-Dublin-Manchester last year and I went through Irish immigration in Dublin. When I landed in Manchester, I just walked off the plane and to baggage claim - no immigration.
