King Charles III is expected to visit Washington, D.C., next month for his first official state visit to the United States, with plans to address a joint meeting of Congress during the week of April 27, according to individuals familiar with the arrangements. The visit would mark a rare appearance by a British monarch before U.S. lawmakers and comes amid broader efforts to highlight the longstanding alliance between the two countries.

If confirmed, the address would be the first by a British monarch to Congress since Queen Elizabeth II spoke to a joint session in 1991. Lawmakers have already adjusted the House schedule to ensure members are in session for the expected remarks.

The visit is tied in part to events commemorating the upcoming 250th anniversary of the United States. It also follows a series of recent high-level exchanges between American and British leaders, including President Donald Trump’s trip to London last September and House Speaker Mike Johnson’s visit earlier this year, where he addressed the British Parliament.

Plans for the trip are still being finalized, but officials are expected to include a formal state dinner at the White House in honor of the king. A formal announcement from the administration is anticipated in the coming days.

The visit comes at a time of heightened international tensions, particularly involving the ongoing conflict between the United States, Israel, and Iran. The situation has prompted diplomatic engagement between Washington and London, with Prime Minister Keir Starmer indicating that the United Kingdom does not intend to become directly involved in the conflict.
