Hello!
First off I am a US citizen.
I am flying from NYC to Dublin with a two hour layover then a connecting flight to London Heathrow. When I land will I be going through passport border control in Dublin? If so, will I then have no passport border control in London? Just trying to simply figure out if I will have to go through passport border control in London. Don't care about customs for I will not have any checked bags.
Thank you!
