Last week, he was “America’s Favorite Houseguest.”

This week, he’s finally an American citizen.

Comedian Tom Green, fresh off a fan favorite cash prize after participating in the second season of Celebrity Big Brother on CBS, officially became a U.S. citizen during a group swearing-in Wednesday in Los Angeles. Green has lived in the States for two decades since he first broke big on MTV. He shared some footage from his ceremony with TMZ.

Recently, he also showed off his citizenship test homework prep during an episode of Celebrity Big Brother.

And here he was earlier this week on KTLA.

Welcome to America, Tom! Officially.
