Can someone clue me in as to when they let foreign cars into NASCAR ?

It depends on what your definition is of a "foreign" car.
A foreign name, foreign built, or foreign owned?
If you mean toyotas (over 15 million made in USA in the last 20 years), they entered the truck series in 2004
then followed into the busch and cup in 2007.
If you mean the other makes that are assembled in mexico and canada with parts from china and elsewhere, well its hard to say exactly when those cars became foreign
