what kind of amount are you thinking of journeyman?
1) supose the book agrees to give you a check for the amount that you can cash in a CR bank
2) you go to the bank and cash it, they don't have kazillion $ sitting in their offices, obviously they would be the target of thieves if they did such a thing
3) you go to the bank and cash it, hopefully you have a bodyguard because it would not surprise me in the least that someone would say "hey this guy has a check for $$$$$$$$$$$$ lets get him when he is leaving the bank", such a thing can happen either because a book employee OR bank employee is aware of what you are going to do
4) when you cash it, you fill a form for CR goverment bank autorities, this is suposed to prevent money laundering (yeah right), this form is mandatory for transactions of 10k and above
5) if you survive you get to the airport and end up in the states
6) chances are customs will not check anything (in over 30 trips, they haven't even asked me the time of the day and I am most definitively a foreigner so............you would have to be really unlucky)
7) get home with cash
