It’s not Renato Viola alone who claims his pizza is extraordinary. It’s not just his wife, who came up with the name for his Mister O1 Extraordinary Pizza. And it’s not even the 200 customers a day who make reservations for one of 18 seats inside his South Beach pizzeria, tucked inside a gray office building where there’s not even a sign out front. No, Renato Viola can claim his pizza is extraordinary because the U.S government says so. 

Viola is in the country on what the U.S. government calls an O-1 visa — for “individuals with extraordinary ability or achievement” — hence the pizzeria’s name. It’s a renewable visa for temporary workers similar to the EB-1 visa for immigrants with “extraordinary ability” that First Lady Melania Trump used to permanently move to the United States — a subject of some controversy last week. But Viola’s proof is in his pizza.
