I am sorry, but this is written into the Constitution of the United States of America:

Article IV, Section 1:

Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof.

It is not even an amendment. It was there from the start.

Tons of laws from the different states affect each other.
