I know that The Professional is the cut US version of the movie. Never seen it. I believe it's around ~15 minutes that was cut?

Léon is the international version, with the ~15 minutes intact.

Léon: The Professional is the title on the DVD box of the US release of Léon, which is identical to the international version.

I'm asking what was cut from Léon (which I've seen and love) to make The Professional (which I haven't seen, and don't really plan to).

Though I guess I could just Google it...
