It appears that Jay-Z and Beyoncé’s trip to Cuba was above board after all. That’s at least what Reuters is reporting, citing a source close to the couple.

The two music stars were in Cuba last week, where they toured Old Havana, posed for pictures with local schoolchildren and dined at the renowned restaurant La Guarida.  The trip also sparked the interest of two Republican congressman from Florida who questioned what kind of license – or special permission – allowed them visit to the island.

Traveling to Cuba is technically not illegal, but the U.S. does prohibit its citizens from spending money in Cuba without the proper license. 

While it’s true that visiting Cuba has gotten a whole lot easier due to easing of restrictions for Americans,  travelers must take part in tours to Cuba that encourage “people to people” contact. There are exceptions for students, journalists, Cuban-Americans and others with legal reasons to travel there.

But without the proper permission, getting caught can result in 10 years in prison and $250,000 in individual fines.

While most people’s trips won’t garner the public scrutiny of Jay-Z and Beyoncé, here are some ways you might still catch some heat if you don’t follow the rules.
