The uniforms that the Venezuelans wear are US Army uniforms with US Military medals and badges arranged randomly.
The flag on the Venezuelans' uniforms and some of the ones on the wall don't have any stars in it, while the Venezuelan flag has 8.
The shield on Raul's chest is not the real Venezuelan shield. The one on the show has two guns, and Hugo Chavez's head.
The Venezuelans mention the people from Caracas visited their sister city of Miami. Caracas is sister cities with Miami; in fact, none of Miami's sister cities are in Venezuela.
During the last conversation between April and the Venezuelan intern some of his words don't match the translation subtitles at all. When he says "Yo me voy en un avión en 6 horas, y si tú no estás me voy a ahorcar" (which is translated as "I'm leaving in a plane in 6 hours, and if you are not in it I'm going to hang myself"), the subtitles say "I am only an intern so my estate is not as big as those of my superiors".
At around 4:35 When Raul (Fred Armisen) says "it is a gift", he is obviously saying something else (right side of the screen).
