President Biden leaves for the United Kingdom on Wednesday, kicking off his first foreign trip as president.

By the numbers: Presidents have made more stops in foreign nations in most recent administrations, though they dropped way off when Donald Trump was in office.

• Theodore Roosevelt became the first U.S. president to take an official diplomatic trip (to Panama); France and Canada have since become the two most-visited nations by U.S. presidents.

Biden is scheduled to meet with the British Prime Minister Boris Johnson, attend the G7 summit and call on Queen Elizabeth while in the U.K., per Reuters.

• He plans to travel to Belgium for EU and NATO meetings, and then to Switzerland to meet with Russian President Vladimir Putin.
