Would puerto rico be considered interstate?

Puerto Rico is not considered a state, so it is not classified as "interstate" in the same way that the 50 U.S. states are. Instead, it is a U.S. territory, which means it has a unique status that allows for some degree of self-governance but is still subject to U.S. Federal Laws. While there are certain legal and economic interactions with the states, the term "interstate" typically refers to activities or relations between U.S. states.
