This is pretty cool!!! If you send a wedding invitation to the President, you will receive a congratulatory letter from him and the First Lady. To invite the President, mail your invitation at least six weeks in advance of your wedding day to: The Honorable (President’s Name) and Mrs. (First Lady) The White House Greetings Office Room 39 1600 Pennsylvania Avenue Washington, DC 20500.
