I need to know what if any documents are mandatory when your layovers are in Italy and Ireland as a US citizen, but you won't be leaving the airport.
My husband has a flight from Morocco to the US, but has layovers in both Pisa Italy and Dublin Ireland, I booked it through kiwi.com, they are giving me lists of documents that have to be filed, but the documents want info on where he will be staying in that country but he won't so I'm confused as to whether he needs to fill them out and how since he has no destination address.
