celebs of this stature rarely make their own travel arrangements. I think it's more likely a huge error on the part of an assistant who didn't properly research the rules before arranging the trip details. Once the error was discovered, this person tried to cover their @$$ by falsifying the required document. I honestly don't think Mr. Depp and Ms Heard had no part in "illegally" bringing the dogs, and when they were made aware, they took the dogs home again. No harm, no foul. I'm sure it's not the first time it's happened ... just the first time it's happened to an A-list actor, which makes for great headlines.
