Have you ever wanted to go on a tour of the White House? You really can. We did. Actually, everyone in my family went on the tour except for me. More on this later. To request a free tour of the White House, you need to make the request through your senator or representative in Congress. According to the White House website, you need to submit your request at least 21 days in advance. Based on my experience, you should apply at least three months in advance. It took about three months before I received the White House tour confirmation.
