Sammi on 'Jersey Shore' -- Stay Out of Miami

Sammi from "Jersey Shore" is officially in the clear after allegedly popping a girl twice in the face at a Miami club last month -- but it's only because she got the hell out of Dodge in the nick of time.

The Miami-Dade State Attorney's Office tells TMZ, the case of Sammi's fists of fury is closed -- because "as a matter of policy, we do not file charges involving misdemeanor crimes when the accused is beyond [our] jurisdiction."

But here's the rub ... if Sammi ever shows her face in Miami again, she could face battery charges.

According to the State Attorney, "This case could be revisited if and when the accused returns."
