This question already has an answer here:
I know there is a popular question already answered - Do I need a visa to transit (or layover) in the Schengen area? - but I am still unclear on some of the rules applying to my specific case, due to the fact that the UK is a 'sort of in the Schengen area but not so' and also some other exceptions arising from the US visa.
I am a Thai passport holder with a Work Permit (Tier 2) in the UK and a B1/B2 visa to the US. I'm flying to the US via Dublin outgoing, then via Zurich and Dublin return. The aforementioned question implies that I'll need a visa for the intra-Schengen transfer on my return, but could I cut the ZUR-DUB leg of the journey and book a ZUR-LHR flight in the Zurich transfer area, or would this be outside the passport check area?
Would I need to carry on all luggage due to the baggage carousel being outside the border control stations?
