What are the legal ramifiications to an American traveling off shore and declaring that he is carrying more than 10K? Does it just open yourself up to IRS questions back home or are there more forms to be filled out at customs? Do you have to show your means for the money or by declaring it over 10K you have fullfilled your legal obligation? With so many casinos throughout the world now is it that uncommon to carry more than 10K to enter those countries?
