To be President of the United States, a person must meet the following constitutional requirements:

• Be at least 35 years old.
• Be a natural-born citizen of the United States.
• Have been a resident of the United States for at least 14 years.

These requirements are established by Article II, Section 1, Clause 5 of the U.S. Constitution and have been in place since the Constitution was written in 1787

. The age requirement of 35 was set by the framers of the Constitution to ensure that the president would have sufficient maturity, wisdom, and life experience to handle the responsibilities of the office. This age was considered a balance between youthful energy and seasoned leadership

. There is no upper age limit for the presidency
