text: i have few dollars saved on my last visit to u.s.now my visa has expired.is it illegal to keep dollars now.? they are traveller cheque bought from american express. please let me know since i will give it back to the bank if it is so. you can exchange them back from the bank. i think that they're insured for loss, and so on. take them to the bank on a day when the dollar is higher in value...you know, a bigger bang for the buck! ;) cheers
