I recently obtained Irish citizenship (and the passport that goes with with it) by virtue of descent. I have never had occasion to use the passport but I am about to visit first the UK and then Paris.
My question is: Can I present my pristine Irish passport when landing at Heathrow from JFK and then when departing France? (I'm assuming there will be no passport asked for when I take the Eurostar from London to the Gare du Nord.)
I would appreciate the experiences of those in a similar situation. Thanks!
