1. be a natural born U.S. citizen. Someone may be born abroad, but only if both parents were citizens of the United States. The only exception to this was for those around at the time the Constitution was adopted. Their requirement was that they had to be a citizen when the Constitution was adopted.
  2. be at least 35 years of age. 
  3. have lived in the United States for at least 14 years to be president. This does not have to be consecutive or even the 14 years leading up to becoming president.

A lot more is needed than this. The candidate must be acceptable to a large number of people across the nation.  These are the minimum constitutional requirements for someone to become president of the United States.
