The procedure for amending the US constitution is precisely described in the constitution itself (which see). First it is passed by Congress, then it must be ratified by the states.
Congress must set its own pay.
They must follow the rules of the constitution .
Amendments to the constitution must be ratified by the states. To become part of the Constitution the Amendment must be approved by three-fourths of the states.
First of all, a two thirds majority of each house of Congress must propose the amendment. Then, a three fourths majority of the states must ratify the amendment.
The Constitution can only be changed when an amendment passed by congress is ratified by 2/3 of all the states in the union. For a state to ratify the change their legislature must pass the change in their state chamber. So the people who change the constitution are the folks you vote for every two to four years.

A constitutional amendment is any change in the US Constitution. Like the constitution, an amendment must be proposed and then adopted by Congress or by state conventions. It must then be ratified by 2/3 of the current states before it becomes part of the Constitution. Amendments can only be superceded by another later amendment, or repealed by one.
