Where does one pass through passport control from the U.S. to Dublin via Heathrow?
Does one pass through passport control from Dublin to Munich? If so, where?
Thanks!
You will pass through immigration in London and Dublin but customs will be on Dublin. (Assuming you are traveling on a U.S. passport.)
Fill in your flight information at this website for step by step instructions at Heathrow:

You will pass through immigration in Munich.
