Tuesday, October 18, marks the 14th and final formal State Arrival Ceremony and State Dinner for a head of state during the Obama administration. These visits serve as an opportunity to celebrate the United States’ relationship with some of our closest allies around the world.

To mark the occasion, I’ve selected some photographs from these visits. In my edit, I focused mostly on the formal and behind-the-scenes situations from the ceremony and dinner rather than on the substantive meetings that also take place. Two of the State Arrivals were moved indoors because of inclement weather and one took place outdoors in the rain. State Dinners have been held on the State Floor, in a tent on the South Lawn, and once in the Rose Garden.

I hope you enjoy my selection of photographs. We will add a couple of photographs from tomorrow’s State Arrival and Dinner for the Prime Minister of Italy.
