You wont "offend" the US for flying from the states... BUT you can't even fly FROM THE STATES!. If you go, you need to fly from Jamaica or Cancun.. Plus you need to have permission 1st, AND the chances of you going are higher if you are a born American citizen, our pathetic President no longer allows Cuban-Americans to visit their own land legally other than every 3 years!. (I wont be voting Bush next election)
