On April 4th 2013, The government-run CubaSí website reported the couple (Jay-Z and Beyoncé) is on a tourist visit, although that would be illegal under the half-century old U.S. embargo.
Additionally there is no doubt that they exceeded the per diem allowed by the Treasury Department.
Homeland Security and Customs should be extra vigilant as Jay-Z may try to illegally import Cuban Cigars to unfairly compete with other Cigar bars in NYC.

How they applied for their license, any fraudulent statement or whether they cleared assisted by any Governmental Agency or Executive Order allowing them to illegally visit the embargoed island country of Cuba.
