Admission to the Union

The Admission to the Union Clause (also known as the New States Clause) is a part of the United States Constitution. It lets Congress add new states to the United States. There were thirteen states when the Constitution came into effect. 37 new states have since been added to the United States by this clause. Each new state has an equal footing with the ones that already exist.^[1]
